Phylogenetic relationship between rabies virus (Lyssavirus rabies) variants from two different species / Relações filogenéticas do vírus da raiva (Lyssavirus rabies) em duas diferentes espécies / Relaciones filogenéticas del virus de la rabia (Lyssavirus rabies) en dos especies diferentes

Rabies is a fatal zoonotic disease that affects several mammals. Hematophagous bats are recognized hosts of the rabies virus, and their main food source is the blood of other mammals, particularly cattle. During feeding, bats transmit the virus to cattle, which are victims of the disease, contributing to economic losses and increasing the risk of infection for humans. Based on this affinity in the rabies cycle between bats and cattle, the objective of this study was to analyze the phylogenetic relationships of rabies virus samples in cattle and bats. The G gene of the rabies virus was chosen for this study because it is directly related to the infection process. Nucleotide sequences of the viral G gene were selected from GenBank for samples obtained from infected cattle and bats. Maximum parsimony analyses were conducted using the Molecular Evolutionary Genetics Analysis software. The Maxima Parsimony tree indicated a phylogenetic relationship between the G genes of both hosts, indicating that the virus evolved from bats to cattle. Analysis of parsimoniously informative sites revealed that the viral G gene carried specific mutations in each host. Knowledge of the evolutionary relationships between the rabies virus and its hosts is critical for identifying potential new hosts and the possible routes of infection for humans.

A Raiva é uma zoonose fatal que infecta várias espécies de mamíferos. Os morcegos hematófagos são reconhecidos como hospedeiros do vírus da Raiva e sua principal fonte de alimento é o sangue de outros mamíferos, especialmente os bovinos. Quando se alimentam, os morcegos transmitem o vírus para o bovino os quais são vítimas da doença, contribuindo para perdas econômicas e riscos de infecção para humanos. Baseado nesta afinidade do ciclo da Raiva entre morcegos e bovinos, o objetivo deste estudo foi analisar as relações filogenéticas de amostras do vírus da Raiva em ambos os hospedeiros, bovinos e morcegos. O gene G do vírus da Raiva foi escolhido para esta pesquisa porque ele está diretamente relacionado ao processo de infecção. Sequências de nucleotídeos do gene G viral foram selecionadas no GenBank a partir de amostras obtidas de bovinos e morcegos infectados. Análises de Máxima Parcimônia foram conduzidas utilizando o software Molecular Evolutionary Genetics Analysis. A árvore de Máxima Parcimônia indicou uma relação filogenética entre o gene G de ambos os hospedeiros, indicando que o vírus evoluiu dos morcegos para os bovinos. A análise dos sítios parcimoniosamente informativos revelou que o gene G viral apresentou mutações específicas em cada hospedeiro. O conhecimento sobre as relações evolutivas do vírus da Raiva e seus hospedeiros é crucial para identificar nos hospedeiros potenciais e novas rotas possíveis de infecção para humanos.

El árbol de Máxima Parsimônia indicó una relación filogenética entre el gen G de ambos huéspedes, indicando que el virus evolucionó de murciélagos a bovinos. El análisis de los sitios parsimoniosamente informativos reveló que el gen G viral presentaba mutaciones específicas en cada huésped. El conocimiento sobre las relaciones evolutivas del virus de la rabia y sus huéspedes es crucial para identificar huéspedes potenciales y nuevas posibles rutas de infección para humanos.

Availability of Raw Material for Wood Based Cricket Bat Industry in Kashmir Valley, India

Kashmir Himalayas is known for its abundant supply of high quality wood suitable for cricket bat industry. The present study aimed to gather comprehensive data on the availability of raw material for the cricket bat industry in Anantnag and Pulwama districts of Kashmir during the specified time period (2017-2018). The main objective of this study was to evaluate the major problems faced by the industry and to assess quality parameters of cleft and the wood used for making these clefts. Shortage of quality raw material, absence of proper marketing channels and irregular electricity supply were the major factors responsible for production shortfall. The units used wood of Salix alba var. caerulea as main raw material while Populus deltoides wood was also used for low quality bats. For the study, latest available official records of Government of Jammu and Kashmir as well as questionnaire based sample survey data were used. The industry produced 15.10 crore clefts that consumed 17,28,532 ft 3 of wood. Sample survey revealed that in 2016, the selected 62 units procured 5,84,557 ft3 of wood with an average of 9,428.33 ft3 per unit.

A neglected normal anatomical structure in mammal: a study in bats and tree shrews / Una estructura anatómica normal desatendida en mamíferos: un estudio en murciélagos y musarañas arborícolas

SUMMARY: The myodural bridge is a dense connective tissue connecting muscles and ligaments to the spinal dura mater in the atlanto-occipital interspace. Some researchers believe that the myodural bridge may play a vital physiological role. It is possible, for instance, that the prevention of spinal dura mater infoldings might be involved in regulated cerebrospinal fluid circulation. For instance, it is possible to prevent spinal dura mater infoldings, regulating cerebrospinal circulation. Bats are nocturnal and the only mammals that can perform a genuine and sustained flight, whereas tree shrews are arboreal mammals that often climb to a high altitude of about 10,000 feet. Both animals have lifestyles that are different from other previously studied mammals. The study of these two animals will shed further light on the existence of the myodural bridge in mammals. Gross anatomical dissection was used to observe the connections between the deep muscles of the neck and the dura mater at the level of the atlanto-occipital interspace. The existing structures were analyzed using conventional and special histological staining techniques. The suboccipital regions in bats and tree shrews contained the rectus capitis dorsal major (RCDma), rectus capitis dorsal minor (RCDmi), oblique capitis anterior (OCA), and oblique capitis posterior (OCP). Dense connective tissue connects the RCDmi to the posterior atlanto-occipital membrane (PAOM) and the latter to the spinal dura mater. The myodural bridge in these mammals shares a similar structure to the myodural bridge in humans. Histological analyses confirmed that the connective fibers of the myodural bridge were primarily type I collagen fibers. In this study, it is supplemented by the existence of the myodural bridge in mammals. This further demonstrates that myodural bridge widely exists in the normal anatomy of mammals. This provides morphological support for a comparative anatomical study of the physiological function of the myodural bridge.

El puente miodural es un tejido conjuntivo denso que conecta los músculos y los ligamentos a la duramadre espinal en el espacio atlanto-occipital. Algunos investigadores creen que el puente miodural puede desempeñar un papel fisiológico vital. Es posible, por ejemplo, que la prevención de los pliegues de la duramadre espinal pueda estar involucrada en la circulación regulada del líquido cefalorraquídeo. En esta instancia, es posible prevenir los pliegues de la duramadre espinal, regulando la circulación cerebro espinal. Los murciélagos son animales nocturnos y los únicos mamíferos que pueden realizar un vuelo real y sostenido, mientras que las musarañas arborícolas son mamíferos arbóreos que a menudo ascienden a una gran altura de unos 10 000 pies. Ambos animales tienen estilos de vida diferentes a los de otros mamíferos previamente estudiados. El estudio de estos dos animales ofrecerá más información sobre la existencia del puente miodural en los mamíferos. Se realizó una disección anatómica macroscópica para observar las conexiones entre los músculos profundos del cuello y la duramadre a nivel del espacio atlanto-occipital. Las estructuras existentes se analizaron mediante técnicas de tinción histológica convencionales y especiales. Las regiones suboccipitales en murciélagos y musarañas arbóreas presentaban el músculo recto dorsal mayor de la cabeza (RCDma), el recto dorsal menor de la cabeza (RCDmi), el oblicuo anterior de la cabeza (OCA) y el oblicuo posterior de la cabeza (OCP). El tejido conjuntivo denso conecta el RCDmi con la membrana atlanto- occipital posterior (PAOM) y esta última con la duramadre espinal. El puente miodural en estos mamíferos comparte una estructura similar al puente miodural en humanos. Los análisis histológicos confirmaron que las fibras conectivas del puente miodural son principalmente fibras de colágeno tipo I. Esto demuestra además que el puente miodural existe ampliamente en la anatomía normal de los mamíferos. Esta investigación proporciona apoyo morfológico para un estudio anatómico comparativo de la función fisiológica del puente miodural.

Value of unenhanced CT-based 5-point predictive score combined with blood glucose detection for predicting short-term prognosis in patients with spontaneous intracerebral hemorrhage / 中国基层医药

Objective:To investigate the value of a 5-point predictive score based on unenhanced CT combined with blood glucose detection for predicting short-term prognosis in patients with spontaneous cerebral hemorrhage.Methods:A total of 102 patients with spontaneous intracerebral hemorrhage who received treatment in Zhejiang Provincial People's Hospital from March 2020 to March 2022 were included in this study and analyzed retrospectively. Blood glucose level was measured and BAT score was used to evaluate hematoma enlargement. After 30 days, Glasgow Outcome Scale was used to evaluate the prognosis of patients. The relationships between blood glucose and BAT score, and between blood glucose and BAT score and prognosis were analyzed. The value of blood glucose and BAT score for predicting short-term prognosis was analyzed.Results:The Glasgow Outcome Scale results showed that among the 102 patients, 24 patients (23.53%) had poor prognosis. The BAT score and blood glucose level in patients with poor prognosis were (3.13 ± 0.68) points and (11.58 ± 2.30) mmol/L, respectively, which were significantly higher than (2.40 ± 0.59) points and (8.88 ± 1.71) mmol/L in patients with good prognosis ( t = 5.10, 5.30, both P < 0.05). Pearson correlation analysis showed that in patients with spontaneous intracerebral hemorrhage, blood glucose level was positively correlated with BAT score ( r = 0.43, P < 0.05). Spearman correlation analysis showed that in patients with spontaneous intracerebral hemorrhage, blood glucose level and BAT level were positively correlated with prognosis ( r = 0.42, 0.47, both P < 0.05). The receiver operating characteristic curve showed that the area under the curve plotted for BAT score combined with blood glucose level for predicting short-term prognosis was 0.874, which was significantly greater than the area under the curve plotted for BAT score alone for predicting short-term prognosis ( Z = 2.54, P < 0.05). Conclusion:A large proportion of patients with spontaneous intracerebral hemorrhage have a poor prognosis. The patients with a poor prognosis have higher blood glucose levels and BAT scores than those with good prognosis. Blood glucose and BAT score have a high value for predicting the prognosis of patients with spontaneous intracerebral hemorrhage.

Bat coronavirus was detected positive from insectivorous bats in Krau Wildlife Reserve Forest

@#Bats are flying mammals with unique immune systems that allow them to hold many pathogens. Hence, they are recognised as the reservoir of many zoonotic pathogens. In this study, we performed molecular detection to detect coronaviruses, paramyxoviruses, pteropine orthoreoviruses and dengue viruses from samples collected from insectivorous bats in Krau Reserve Forest. One faecal sample from Rhinolophus spp. was detected positive for coronavirus. Based on BLASTN, phylogenetic analysis and pairwise alignment-based sequence identity calculation, the detected bat coronavirus is most likely to be a bat betacoronavirus lineage slightly different from coronavirus from China, Philippines, Thailand and Luxembourg. In summary, continuous surveillance of bat virome should be encouraged, as Krau Reserve Forest reported a wide spectrum of biodiversity of insectivorous and fruit bats. Moreover, the usage of primers for the broad detection of viruses should be reconsidered because geographical variations might possibly affect the sensitivity of primers in a molecular approach.

Current understanding of an Emerging Coronavirus using in silico approach: Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) / Compreensão atual de um coronavírus emergente usando abordagem in silico: síndrome respiratória aguda grave - coronavírus-2 (SARS-CoV-2)

Abstract Novel coronavirus (nCoV) namely "SARS-CoV-2" is being found responsible for current PANDEMIC commenced from Wuhan (China) since December 2019 and has been described with epidemiological linkage to China in about 221 countries and territories until now. In this study we have characterized the genetic lineage of SARS-CoV-2 and report the recombination within the genus and subgenus of coronaviruses. Phylogenetic relationship of thirty nine coronaviruses belonging to its four genera and five subgenera was analyzed by using the Neighbor-joining method using MEGA 6.0. Phylogenetic trees of full length genome, various proteins (spike, envelope, membrane and nucleocapsid) nucleotide sequences were constructed separately. Putative recombination was probed via RDP4. Our analysis describes that the "SARS-CoV-2" although shows great similarity to Bat-SARS-CoVs sequences through whole genome (giving sequence similarity 89%), exhibits conflicting grouping with the Bat-SARS-like coronavirus sequences (MG772933 and MG772934). Furthermore, seven recombination events were observed in SARS-CoV-2 (NC_045512) by RDP4. But not a single recombination event fulfills the high level of certainty. Recombination mostly housed in spike protein genes than rest of the genome indicating breakpoint cluster arises beyond the 95% and 99% breakpoint density intervals. Genetic similarity levels observed among "SARS-CoV-2" and Bat-SARS-CoVs advocated that the latter did not exhibit the specific variant that cause outbreak in humans, proposing a suggestion that "SARS-CoV-2" has originated possibly from bats. These genomic features and their probable association with virus characteristics along with virulence in humans require further consideration.

Resumo O novo coronavírus (nCoV), nomeadamente "SARS-CoV-2", foi considerado responsável pela pandemia atual iniciada em Wuhan (China) desde dezembro de 2019 e foi descrito com ligação epidemiológica à China em cerca de 221 países e territórios até agora. Neste estudo, caracterizamos a linhagem genética do SARS-CoV-2 e relatamos a recombinação dentro do gênero e subgênero dos coronavírus. A relação filogenética de 39 coronavírus pertencentes a seus quatro gêneros e cinco subgêneros foi analisada usando o método de Neighbour-joining usando MEGA 6.0. Árvores filogenéticas do genoma de comprimento total, várias proteínas (espícula, envelope, membrana e nucleocapsídeo), sequências de nucleotídeos foram construídas separadamente. A recombinação putativa foi testada via RDP4. Nossa análise descreve que o "SARS-CoV-2", embora mostre grande semelhança com as sequências de Bat-SARS-CoVs em todo o genoma (dando semelhança de sequência de 89%), exibe agrupamento conflitante com as sequências de coronavírus do tipo Bat-SARS (MG772933 e MG772934) Além disso, sete eventos de recombinação foram observados em SARS-CoV-2 (NC045512) por RDP4. Mas nem um único evento de recombinação preenche o alto nível de certeza. A recombinação está alojada mais em genes de proteína de pico, principalmente, do que no resto do genoma, indicando que o cluster de ponto de interrupção surge além dos intervalos de densidade de ponto de interrupção de 95% e 99%. Os níveis de similaridade genética observados entre "SARS-CoV-2" e Bat-SARS-CoVs defendem que o último não exibe a variante específica que causa surto em humanos, sugerindo que "SARS-CoV-2" tenha se originado possivelmente de morcegos. Essas características genômicas e sua provável associação com as características do vírus, juntamente com a virulência em humanos, requerem uma consideração mais aprofundada.

First report on the detection of Japanese encephalitis virus in fruit bats from India

Japanese encephalitis (JE) is a mosquito borne viral zoonotic disease and JE virus (JEV) is responsible for causing several children deaths every year in India. Since 1978, cases of JE have been reported from Gorakhpur district of Uttar Pradesh state annually. The knowledge on the role played by wildlife reservoirs in the sylvatic transmission and maintenance of JE virus remains limited. Bats are reservoir hosts for several emerging and re-emerging viral pathogens but their role in zoonotic cycle of JEV has not been elucidated yet. In Gorakhpur district of Uttar Pradesh, 52 fruit bats were found dead on 26 May 2020. The post-mortem report of the bat samples conducted at the Indian Veterinary Research Institute stated that the bats died due to brain hemorrhage, caused by excessive heat. The brain tissue samples of the bats were subjected to investigation using molecular techniques to determine the presence of JEV. The present work reports for the first time the detection of JEV in brain samples of bats from India. The viral load ranging from 8 to 18 copies/reaction was detected in brain samples by TaqMan real Time RT-PCR. The low viral load might be the reason for the absence of apparent clinical signs in bats and suggests the probable role of fruit bats in maintaining the JEV in nature.

Predictive value of BAT score in the prognosis of patients with spontaneous intracerebral hemorrhage / 中华急诊医学杂志

Objective:To study the predictive value of BAT score for the prognosis of patients with spontaneous intracerebral hemorrhage (sICH).Methods:A retrospective analysis of 93 sICH patients in the Emergency Department of the Second Affiliated Hospital of Wannan Medical College from January 2018 to December 2020 was conducted, and the patients were classified into the good prognosis group ( n=34) and the poor prognosis group ( n=59) according to the Glasgow Outcome Score (GOS) 3 months after the discharge. Clinical data such as basic data of patients, admission vital signs, laboratory indicators, National Institute of Health stroke scale (NIHSS) score and BAT score and other clinical data of the two groups were compared. Multivariate logistic regression was used to analyze the risk factors affecting poor prognosis of sICH patients. The receiver operating characteristic (ROC) curve was drawn to analyze predictive value of BAT score for poor prognosis of sICH patients. Results:The admission systolic blood pressure, white blood cell count, hypertension complications, emergency BAT score and NIHSS score of patients in the poor prognosis group were significantly higher than those in the good prognosis group ( P<0.05). Multivariate logistic regression analysis indicated that the admission systolic blood pressure ( OR=1.024, 95% CI: 1.002~1.046, P=0.035) and emergency BAT score ( OR=2.640, 95% CI: 1.445-4.825, P=0.002) could accurately predict the poor prognosis of sICH patients. ROC curve analysis showed that the area under ROC curve (AUC) of BAT score was 0.792, the sensitivity was 79.3%, and the specificity was 76.5%. The AUC of systolic blood pressure for predicting poor prognosis of sICH patients was 0.701, and the sensitivity was 55.2%, and the specificity was 88.2%. The AUC of BAT score combined with systolic blood pressure for predicting poor prognosis of sICH patients was 0.835. Conclusions:BAT score and admission systolic blood pressure could more accurately predict poor prognosis of sICH patients. The combination of them had a higher efficacy in predicting poor prognosis of sICH patients after 3 months.

Filamentous fungi occurrence on Molossus molossus (Pallas, 1766) (Chiroptera: Molossidae) present in an Atlantic Forest remnant in Southern Brazil / Ocorrência de fungos filamentosos em Molossus molossus (Pallas, 1766) (Chiroptera: Molossidae) presentes em um remanescente da Mata Atlântica no Sul do Brasil

Abstract The bats usually inhabit shelters with favorable conditions for fungal proliferation, including pathogenic and opportunistic species. The fungal diversity present on bats is little known and the studies are scarce in Brazil, which only a work has been performed in Cerrado and Pantanal biomes. Therefore, the objective of this study was evaluating the occurrence of filamentous fungi on the rostral region of Molossus molossus in an Atlantic Forest remnant of Brazil. The bats were captured with mist nets installed outside a shelter located in the municipality of Treviso, (28°29'23"S and 49°31'23"W), south region of state Santa Catarina. With a swab sterile moistened in saline solution, samples from the rostral region were obtained from all captured M. molossus individuals. The samples were taken to the laboratory for analysis and isolation in different culture media, followed of identification of fungal through the microculture technique. In total, 15 individuals were captured, which five fungal genus and 19 taxa were identified. Among the taxa registered, Aspergillioides sp.2, (47%), Penicillium sp.1 (33%), Chrysonilia sp. (33%), Cladosporium sp. (27%) were classified as little constant. In terms of abundance, Penicillium sp.1 (34%), Aspergillioides sp.2 (21%) and Aspergillus sp.2 (11%) were the most abundant in the samples. The results showed the occurrence of high diversity fungal in the rostral region of M. molossus in the Atlantic Forest, which is higher than observed in others Brazilian biomes. Some fungal genera found may harbor pathogenic and opportunistic species that need to be identified for preventing potential disease well as for bat conservation projects.

Resumo Os morcegos comumente abrigam-se em locais com condições favoráveis para proliferação fúngica, incluindo espécies patogênicas e oportunistas. A diversidade fúngica presente nos morcegos é pouco conhecida e os estudos são escassos no Brasil, no qual apenas um trabalho tem sido realizado nos biomas do Cerrado e Pantanal. Portanto, o objetivo deste estudo foi avaliar a ocorrência de fungos filamentosos na região rostral de Molossus molossus em um remanescente da Mata Atlântica no sul do Brasil. Os morcegos foram capturados com redes-de-neblina instaladas na saída de um abrigo localizado no município de Treviso (28°29'23"S e 49°31'23"W), região sul do estado de Santa Catarina. Com um swab esterilizado e umedecido em solução salina, amostras da região rostral foram obtidas de todos os indivíduos de M. molossus capturados. As amostras foram levadas ao laboratório para análise e isolamento em diferentes meios de cultura, seguido de identificação taxonômica fúngica pela técnica de microcultivo. No total, 15 indivíduos foram capturados, nos quais 5 gêneros fúngicos e 19 taxa foram identificados. Dentre os taxa registrados foram classificados como pouco constante Aspergillioides sp.2, (47%), Penicillium sp.1 (33%), Chrysonilia sp. (33%), Cladosporium sp. (27%). Em termos de abundância, Penicillium sp.1 (34%), Aspergillioides sp.2 (21%) e Aspergillus sp.2 (11%) foram os mais abundantes nas amostras. Os resultados mostraram ocorrência de elevada riqueza de fungos na região rostral de M. molossus na Mata Atlântica, riqueza essa que é superior àquela observada para outros biomas brasileiros. Alguns gêneros fúngicos encontrados podem abrigar espécies patogênicas e oportunistas que precisam ser identificadas tanto para prevenir potenciais doenças, assim como, para os projetos de conservação dos morcegos.

A growing body of evidence has indicated that G-protein coupled bile acid (BA) receptor TGR5 (also known as Gpbar-1) is a potential drug target to treat obesity and associated metabolic disorders. We have identified notoginsenoside Ft1 (Ft1) from

Refugios diurnos del murciélago Rhynchonycteris naso (Chiroptera: Emballonuridae) en Laguna de Términos, Campeche, México / Diurnal roosts of the bat Rhynchonycteris naso (Chiroptera: Emballonuridae) in Laguna de Términos, Campeche, Mexico

Introducción: La selección de refugios diurnos es un proceso crucial para los murciélagos debido a su influencia en la ecología, organización social y supervivencia de sus poblaciones. El murciélago narigón (Rhynchonycteris naso) es una especie protegida por leyes de México, cuyos refugios y zonas de forrajeo, están estrictamente asociados a cuerpos de agua, principalmente ríos. Por lo tanto, cambios en la calidad del agua suponen un riesgo para sus poblaciones. Sin embargo, el conocimiento sobre el estado actual de sus poblaciones y refugios diurnos en México, es escaso. Objetivo: Ubicar y describir los refugios diurnos de R. naso y evaluar la relación del tamaño del grupo de murciélagos con las características de los refugios, la salinidad y el pH del agua donde habitan. Métodos: De marzo a octubre 2015, se realizaron búsquedas de refugios diurnos mediante recorridos en lancha a lo largo de ríos, arroyos y lagunas, en once sitios del Área de Protección de Flora y Fauna Laguna de Términos, Campeche México. Por cada refugio localizado se registró el tamaño del grupo y su acomodo en el refugio, el tipo de refugio, el tipo de vegetación, la cobertura, la distancia entre refugios, el diámetro del tronco, la salinidad y el pH. Para investigar el efecto de las variables registradas en los refugios sobre el tamaño de cada grupo, se ajustaron Modelos Lineales Generalizados. Resultados: Encontramos 48 refugios en troncos secos, cortezas de árboles y puentes, asociados a cuerpos de agua dulce y oligohalina, principalmente en vegetación de manglar. El promedio (± EE) del tamaño del grupo fue de 5.3 ± 0.48 para los refugios naturales y de 22.6 ± 9.54 para los artificiales. Encontramos una relación significativa con el tipo de refugio, el tipo de vegetación y el diámetro del tronco. Los refugios con tamaño de grupo mayores presentaron un acomodo agregado. Se localizaron 40 refugios sobre cuerpos de agua dulce y ocho en oligohalina con alto nivel de agrupamiento. Conclusiones: La mayor incidencia de refugios en sitios de agua dulce y ligeramente ácida, es explicada bajo la teoría del óptimo forrajeo. Debido a que el área de estudio se encuentra en el límite de su distribución, el manglar representa el tipo de vegetación más importante para garantizar la permanencia de las poblaciones de R. naso. Adicionalmente, debido a que en algunas porciones de la zona de estudio no fue posible encontrar refugios, es crucial llevar a cabo estudios sobre la calidad del agua y los niveles de contaminación en la región. Este estudio proporciona información relevante sobre las poblaciones del murciélago Rhynchonycteris naso con implicaciones directas sobre su conservación en zonas ribereñas y humedales costeros.

Introduction: The selection of day-roost is a crucial process for bats because it influences the ecology, social organization, and survivorship aspects of their populations. Proboscis bat (Rhynchonycteris naso) is a protected species by Mexican law, whose foraging and roosting areas are strongly associated with bodies of water, primarily rivers. Therefore, alterations in the water quality pose a risk to their populations. However, knowledge of the current state of their populations and roosting ecology is very poor in Mexico. Objectives: To locate and to describe R. naso's diurnal roosts, and to evaluate the relationship of the group size per roost with the characteristics of the diurnal roost, the salinity and pH of the water where they inhabit. Methods: From March to October 2015, we searched diurnal roost through boat tours along rivers, streams, and lagoons, in eleven sites in the Laguna de Términos Flora and Fauna Protection Area, Campeche, Mexico. For each localized roost, we recorded the group size, and their spatial distribution, the type of roost and vegetation, the distance between roosts, the diameter of trunk, the salinity, and pH. In order to investigate the effect of the variables recorded in diurnal roost on size group, generalized linear models were adjusted. Results: We found 48 diurnal roost in dead tree-trunks, tree bark and bridges, associated with freshwater, and oligohaline bodies, mainly in mangrove vegetation. The average size of the groups was 5.3 ± 0.48 and 22.6 ± 9.54 in natural and artificial roosts, respectively. We found a significant relationship with the type of roost, type of vegetation and diameter of trunk. Roosts with larger groups of bats presented an aggregated distribution. We located 40 diurnal roosts on freshwater bodies and eight in oligohaline with a high grouping level. Conclusions: Greater incidence of roost in fresh and lightly acid water is explained under optimal foraging theory. Because the study area is found in the limit of their distribution, mangrove is a very important vegetation type to guarantee the establishment of R. naso populations. Also, due no roosts were found in some portions of the study zone, quality of water, and contaminant level studies are crucial. This study provides relevant information on their populations with direct implications for the conservation in coastal areas.

Frugivorous bat (Chiroptera: Phyllostomidae) community structure and trophic relations in Atlantic Forest fragments

We evaluated the structure of a community of frugivorous bats using composition and abundance patterns, niche amplitude and food overlap of these animals in four Atlantic Forest fragments, each one exposed to different conservation realities. For twelve months, we captured six bat species and found the seeds of 13 species of pioneering plants in 158 fecal samples. The most abundant bat species were Artibeus planirostris (25.4%), Artibeus lituratus (24.1%) and Carollia perspicillata(23.9%). Only one fragment (Fazenda Unida), the most conserved area, exhibited a significantly different composition and abundance of species. We found low trophic niche amplitude values (<0.60), associated to high food overlaps. Our results suggest that bats can adjust their foraging strategy to deal with food availability variations. By favoring pioneering plant species, the fragmentation process noted of the studied areas creates an attractive environment for bats more tolerant to this type of disturbance. The sampled areas represent important secondary forest remnants in southern Brazil that require attention to avoid an even greater loss of bat diversity.

Predictive risk model of livestock rabies occurrence in Peru / Modelo de risco preditivo para a ocorrência da raiva bovina no Peru

Livestock rabies is endemic in Peru. Hence, its persistence and annual dissemination represent an important economic impact, especially for impoverished farming communities. The disease is mostly transmitted by the hematophagous bat Desmodus rotundus. The present study aimed to adapt an existing predictive model of the occurrence of livestock rabies to Peru, in which the risk of rabies transmission from bats to livestock was estimated using decision-tree models of receptivity and vulnerability. Official rabies surveillance data between 2010 and 2015 were used along with possible risk factors, such as livestock biomass, environmental changes, and geomorphological characteristics. Several scenarios were established to evaluate the prediction of the occurrence of livestock rabies cases by determining more than one cut-off point of the receptivity variables. During the study period, the precision of the model was estimated through the sensitivity (39.46%) and specificity (98.64%) by using confusion matrices. Targeting control efforts, especially in districts with a high estimated risk, could represent the prevention of a significant proportion of livestock rabies cases, which would optimize the human and economic resources of the Peruvian surveillance service. However, the quality of data produced by the surveillance should be improved not only to obtain higher model precision but also to allow the adequate planning of control actions.(AU)

Raiva de herbívoros é endêmica no Peru. Consequentemente, sua disseminação persistente e anual representa um importante impacto econômico, especialmente às comunidades rurais empobrecidas. A doença é principalmente transmitida pelo morcego hematófago Desmodus rotundus. Este estudo tem por objetivo adaptar um modelo preditivo pré-existente às ocorrências de raiva de herbívoros no Peru, no qual o risco de transmissão de morcegos para os herbívoros foi estimado por meio de árvores de cenários de receptividade e vulnerabilidade. Foram usados os dados oficiais de vigilância da raiva entre 2010 e 2015, assim como os possíveis fatores de risco, tais quais a biomassa de animais, alterações ambientais e características geomorfológicas. Diversos cenários foram criados para avaliar a predição da ocorrência da raiva por meio da determinação de diversos pontos de corte das variáveis de receptividade. Durante o período de estudo, a precisão do modelo foi estimada por meio da sensibilidade (39,46%) e especificidade (98,64%), utilizando matrizes de confusão. Focando em esforços de controle, especialmente em distritos com elevado risco estimado, seria possível prevenir uma proporção significativa dos focos, o que poderia otimizar os recursos humanos e econômicos do serviço oficial peruano. Entretanto, a qualidade dos dados produzidos pelo sistema de vigilância deveria ser melhorada não somente para obter maior precisão do modelo, mas também para possibilitar o melhor planejamento das ações de controle desta doença.(AU)

Abstract The introduction of new technologies in baseball has optimized the systems for recording and analyzing information, both in training and in the game, contributing to a more accurate control of a player's performance. In this work, it is applied the Blast Motion Baseball sensor which objective is to identify the variables significantly influencing the performance of batters in Cuban baseball. There were chosen batters (N=24) belonging to the National Baseball Series LIX because it constitutes the national event of higher level in Cuban baseball. The information was recorded during batting practice, while the batter was performing the task of connecting balls thrown by the coach from the front toss, over the arm at a distance of 30 feet and at a speed of less than 50 mph. The results of Blast Motion Baseball were then compared with the official statistics of the LIX National Baseball Series. It was shown that batters with higher bat speed, higher top hand speed and more power achieved greater offensive performance. Therefore, knowing these characteristics of the swing in real time helps to perfect the training process and predict the sports performance of a batter.

Un registro de hipertrofia del trago del murciélago frugívoro de gran tamaño Artibeus lituratus (Chiroptera: Phyllostomidae) / A record of hypertrophy of the tragus of great fruit-eating bat Artibeus lituratus (Chiroptera: Phyllostomidae)

Resumen En este trabajo, reportamos y describimos evidencia de una anomalía en el trago de un individuo de Artibeus lituratus, capturado en los Andes Centrales de Colombia. En junio de 2019, durante un trabajo de campo en el Departamento de Caldas, municipio de Aranzazu, quedó atrapado un individuo de A. lituratus con inusual forma de trago. Este individuo tenía un trago de forma cilíndrica y asimetría. El individuo fue recogido y depositado en el Museo de Historia Natural de la Universidad de Caldas (MHN-UCa). Se realizó una revisión de la literatura para encontrar casos similares utilizando motores de búsqueda, pero no se encontraron informes previos de la anomalía. Además, revisamos el trago de los especímenes en el MHNUCa y ninguno de ellos presentaba malformaciones similares. Concluimos que esta anomalía no se había registrado previamente en Chiroptera.

Abstract In this work, we report and describe evidence of an anomaly in the tragus of an individual of Artibeus lituratus, captured in the Central Andes of Colombia. During field work in the Department of Caldas, municipality of Aranzazu, one individual of A. lituratus with unusual tragus form was trapped. This individual had a tragus with cylindrical shape and asymmetry. The individual was collected and deposited at the Museum of Natural History of the University of Caldas (MHN-UCa). A literature review was conducted to find similar cases using searching engines, but no previous reports of the anomaly were find. Furthermore, we reviewed the tragus of vouchers at the MHN-UCa and none of these had similar malformations. We concluded that this anomaly has not previously registered in Chiroptera.

The Role Of Morphological Traits On The Batting Performance Of Cricket Batsmen – A Review Study

Background: The batting performance is assessed by considering the batting average and strike rate of a batsman. With the induction of T-20 cricket matches, the strike rate of a batsman has gained much attention from coaches and team management. To increase the strike rate a batsman required to hit powerful shots for boundaries, which assist in making maximum scores at the minimum ball. Therefore, this investigation was planned to determine the effect of body size on the batting performance of cricket batsman. Methods: the literature for this study was selected for cricket coaching manual, cricket books, cricket batting videos, a biography of cricket batsmen, research articles. The academic documents were downloaded and shortlisted from Google Scholar, Research Gate, EBSCO, and ProQuest from 1990 to 2019. Results: The synthesized literature review concludes, stature, longer legs, longer arms, and lean body mass of a batsman show positive effects on the execution of powerful shots in cricket. Furthermore, the maximum strength of muscles assists a batsman to boost up the initial velocity of bat swing to accomplish the ball speed for a successful and powerful shot. Conclusions: Although stature and longer limbs of batsmen are associated with batting performance. On the other hand, the specific training would also enhance the capacity of cricket batsman for powerful shots in cricket. A future study was proposed to investigate the effect of training on the batting performance.

Review of the distribution of Lophostoma carrikeri (Chiroptera: Phyllostomidae), with range extension to transitional vegetation zones in the southwestern Amazon

Lophostoma carrikeri has been mostly recorded within the Amazon biome. There are scarce records in the northern Brazilian Amazon, but also records outside this biome, which were neglected in literature. The aim of this study was to update and extend the distribution of L. carrikeri. Seven new localities in Brazil were provided, including the first records for the states of Rondônia and Mato Grosso, filling a large gap in the species distribution, and three additional records for the state of Pará. Our results reinforce the notion that L. carrikeri is widely distributed in the Amazon, but is also present in other biomes in Brazil, such as Caatinga, Cerrado, and transitional areas. (AU)
