Expanding the knowledge of the bat fauna of the Brazilian Caatinga: new geographical records of molossid bats (Chiroptera, Molossidae) for the Chapada Diamantina region, with taxonomic notes.

The Caatinga, an exclusive biome in Brazil, is the largest tropical dry forest area in the Americas. It is characterized by a semi-arid climate and various soils that harbor a great diversity of flora and fauna. Novel records of aerial insectivorous bat species in the family Molossidae in the Chapada Diamantina, northeastern Brazil are presented. The study is based on field sampling of 115 molossid bat specimens from six genera and 12 taxonomically confirmed species, along with four taxa requiring further evaluation for definitive species identification. All specimens were obtained using mist nets around a small freshwater lagoon surrounded by semideciduous dry forest. The verified genera were Cynomops, Eumops, Molossops, Molossus, Neoplatymops, and Nyctinomops. Our findings enhance the understanding of bat diversity in the Brazilian Caatinga, with the first records of Eumopsdelticus, E.bonariensis, and Molossuscurrentium. The most abundant species were Molossusrufus, Eumopsglaucinus, Cynomopsplanirostris, Nyctinomopslaticaudatus, and Molossusmolossus. Previously unreported morphological and morphometric variations for these Caatinga taxa were examined. Additionally, information on sexual dimorphism in craniodental characteristics of Molossopstemminckii and variations in the presence of the sagittal crest in Neoplatymopsmattogrossensis are provided. Based on the voucher specimens from this study, the recognized number of species of Molossidae known from the Caatinga has increased to 21. Our results offer new insights into the taxonomy and biogeography of Neotropical molossids, highlighting their importance as members of bat communities in dry forest ecosystems from northeastern South America.

Forensic Geochemistry Reveals International Ship Dumping as a Source of New Oil Spill in Brazil's Coastline (Bahia) in Late 2023.

In the present study, we applied forensic geochemistry to investigate the origin and fate of spilled oils like tarballs stranded at the beaches of Bahia, in northeastern Brazil, in September 2023, based on their fingerprints. Saturated and aromatic compounds were assessed by gas chromatography, and the oceanic surface circulation patterns were deciphered to determine the geographic origin of the spill. Contamination by petroleum represents an enormous threat to the unique, species-rich ecosystems of the study area. The geochemical fingerprint of the oil spilled in 2023 did not correlate with those of previous events, including the one in 2019, the one in early 2022 in Ceará, and an extensive spill across the Brazilian Northeast in late 2022. However, the fingerprint did correlate with crude oils produced by Middle Eastern countries, most likely Kuwait. The oil of the 2023 spill had a carbonate marine origin from early mature source rocks. These findings, together with the moderate weathering of the 2023 tarballs and the ocean circulation patterns at the time of the event, indicate that the oil was discharged close to the shore of Brazil, to the east or southeast of Salvador, by a tanker on an international route in the South Atlantic.

Triatominae (Hemiptera: Reduviidae) fauna in bird nests: the case of Morrinhos, Ceará, Brazil.

Triatominae are associated with various Brazilian habitats, including bird nests, animal burrows, and peridomestic structures. Despite extensive studies on triatomines in domiciliary environments in Ceará, Brazil, there has been limited research on their presence in the wild. This study focuses on the municipality of Morrinhos in Ceará, which is characterized by a Caatinga biome and riparian forests along the Acaraú River. During the study, a total of 185 nests of Pseudoseisura cristata were analyzed in rural locations and triatomines were collected in 26 nests from 12 different locations. A total of 117 triatomines was collected, belonging to three species: Psammolestes tertius, Rhodnius nasutus, and Triatoma pseudomaculata. Rhodnius nasutus was the only species found in a nest inhabited by Didelphis albiventris. Nests of P. cristata serve as shelters for various animals, providing an ideal environment for triatomines to establish colonies due to their proximity to food sources and their generalist feeding habits. The incorporation of anthropogenic materials by birds in nest construction can indirectly affect the presence of other animals that may serve as food sources for triatomines. Understanding the interactions between triatomines, birds, and their habitats is essential for assessing the risks associated with triatomine infestation in wild ecosystems.

Consumption of a multi-deficient diet causes dynamic changes in the intestinal morphofunctional barrier, body composition and impaired physical development in post-weaning mice.

Few studies have focused on nutrient-deficient diets and associated pathobiological dynamics of body composition and intestinal barrier function. This study evaluated the impact of a nutrient-deficient diet on physical development and intestinal morphofunctional barrier in mice. C57BL/6 (21 days of age) mice were fed a Northeastern Brazil regional basic diet (RBD) or a control diet for 21 d. The animals were subjected to bioimpedance analysis, lactulose test, morphometric analysis and quantitative reverse transcription-PCR to evaluate tight junctions and intestinal transporters. RBD feeding significantly reduced weight (P < 0·05) from day 5, weight gain from day 3 and tail length from day 14. The intake of RBD reduced total body water, extracellular fluid, fat mass and fat-free mass from day 7 (P < 0·05). RBD induced changes in the jejunum, with an increase in the villus:crypt ratio on day 7, followed by reduction on days 14 and 21 (P < 0·05). Lactulose:mannitol ratio increased on day 14 (P < 0·05). Changes in intestinal barrier function on day 14 were associated with reductions in claudin-1 and occludin, and on day 21, there was a reduction in the levels of claudin-2 and occludin. SGLT-1 levels decreased on day 21. RBD compromises body composition and physical development with dynamic changes in intestinal barrier morphofunctional. RBD is associated with damage to intestinal permeability, reduced levels of claudin-1 and occludin transcripts and return of bowel function in a chronic period.

Contribution to the knowledge of Brazilian troglobitic Pseudoscorpiones (Arachnida): description of Pseudochthonius lubueno sp. nov. (Chthoniidae) from Serra do Ramalho karst area, state of Bahia, Brazil

ABSTRACT Pseudochthonius lubueno sp. nov., a new obligatory cave-dwelling pseudoscorpion species is described from Gruna da Altina cave, the fifth species of the genus in the region of Serra do Ramalho karst area, southwestern Bahia, Brazil. This genus occurs in South and Central America, sub-Saharan central Africa, and in the Arabian Peninsula. The new species can be identified by the following combination of characters: eyes or eyespots absent, coxa I with two and coxa II with 4-5 coxal spines, without microdenticles on the fixed pedipalpal finger, rallum with five blades, ratio ist-est/ist-esb = 1.9. With this new description, the genus now includes 15 species from Brazil: P. biseriatus Mahnert, 2001, P. brasiliensis Beier, 1970, P. diamachi Prado & Ferreira, 2023, P. gracilimanus Mahnert, 2001, P. heterodentatus Hoff, 1946, P. homodentatus Chamberlin, 1929, P. koinopoliteia Prado & Ferreira, 2023, P. lubueno sp. nov., P. orthodactylus Muchmore, 1970, P. olegario Schimons ky, 2022, P. pali Prado & Ferreira, 2023, P. ramalho Assis, Schimonsky & Bichuette, 2021, P. ricardoi Mahnert, 2001, P. strinatii Beier, 1969 and P. tuxeni Mahnert, 1979. The new species shows troglomorphic characteristics such as the depigmentation of the carapace and the absence of eyes. In addition, illustrations, diagnoses, an identification key for cave-dwelling species of the genus, and distribution maps for all Brazilian species of Pseudochthonius are provided.

Sponges as libraries: Increase in microplastics in Cinachyrella alloclada after 36 years.

Many studies investigated the presence and effects of microplastics in marine species, but data about sponges are still incipient. We quantified these pollutants in a population of the tropical sponge Cinachyrella alloclada, comparing museum specimens sampled in 1981 with specimens sampled in 2017. The mean number of microplastics in specimens collected decades ago was one order of magnitude lower (0.13 ± 0.40/g of sponge tissue) than those sampled more recently (1.37 ± 0.94/g). We observed microplastics in only 10 % of the specimens collected in 1981 but in 80 % of those from 2017. According to Raman spectroscopy, fibers in C. alloclada consisted of polypropylene. Our results reinforce the importance of natural history collections to reduce the gap of knowledge on the interaction between marine sponges and microplastics.

Reproductive and ecological similarity between Caretta caretta (Linnaeus, 1758) and Eretmochelys imbricata (Linnaeus, 1766) in southern Bahia (Brazil) / Semelhança reprodutiva e ecológica entre Caretta caretta (Linnaeus, 1758) e Eretmochelys imbricata (Linnaeus, 1766) no sul da Bahia (Brasil)

This study evaluates the reproductive and ecological similarity between loggerhead sea turtle (Caretta caretta) and Hawksbill sea turtle (Eretmochelys imbricata) two species of sea turtles on the southern coast of Bahia (Brazil) during two breeding seasons (October to April 2013 to 2015). The study covers a 10-km area composed of three beaches, Pompilho, Itacarezinho and Patizeiro beach, which are 5, 3, and 2 km long, respectively. Daily field surveys were performed for 102 days to assess patterns between the studied species, using the non-metric multidimensional scaling order and the Spearman correlation analysis to obtain the oviposition pattern of the two species. Moreover, Kruskall-Wallys tests were performed to review the differences in the number of hatchlings on the three beaches. The NMDS proved the species are very similar from an ecological perspective since as there were three clear groupings in terms of the number of hatchlings on the three beaches. With reference to the number of nests, a negative correlation was observed in the two species. Regarding the hatching activity of both species on the three beaches studied, a larger amount of C. caretta and E. imbricata hatchlings was found on Pompilho beach, followed by Patizeiro and Itacarézinho. These findings influence management strategies to reduce anthropogenic impact and contribute to the conservation of these two endangered sea turtle species.

Este estudo avalia a semelhança reprodutiva e ecológica entre a tartaruga cabeçuda (Caretta caretta) e a tartaruga-de-pente (Eretmochelys imbricata) duas espécies de tartarugas marinhas no litoral sul da Bahia (Brasil) durante duas estações reprodutivas (outubro a abril de 2013 a 2015) . O estudo abrange uma área de 10 km composta por três praias, Pompilho, Itacarezinho e praia do Patizeiro, com 5, 3 e 2 km de extensão, respectivamente. Foram realizados levantamentos diários de campo durante 102 dias para avaliar padrões entre as espécies estudadas, utilizando a ordem de escala multidimensional não métrica e a análise de correlação de Spearman para obter o padrão de oviposição das duas espécies. Além disso, testes de Kruskall-Wallys foram realizados para revisar as diferenças no número de filhotes nas três praias. O NMDS provou que as espécies são muito semelhantes do ponto de vista ecológico, pois havia três agrupamentos claros em termos do número de filhotes nas três praias. Com relação ao número de ninhos, foi observada correlação negativa nas duas espécies. Em relação à atividade de eclosão de ambas as espécies nas três praias estudadas, uma maior quantidade de filhotes de C. caretta e E. imbricata foi encontrada na praia do Pompilho, seguida de Patizeiro e Itacarézinho. Esses achados influenciam as estratégias de manejo para reduzir o impacto antropogênico e contribuir para a conservação dessas duas espécies de tartarugas marinhas ameaçadas de extinção.

Triatomine fauna in the state of Bahia, Brazil: What changed after 40 years of the vector-control program?

ABSTRACT Background: Neglected tropical diseases are a growing threat to global health, and endemic Chagas disease has emerged as one of the most important health problems in America. The main strategy to prevent Trypanosoma cruzi transmission is chemical control of vectors. This study presents a descriptive analysis of synanthropic triatomines before and after the implementation of a vector-control program in Bahia, Brazil. Methods: Descriptive analysis and geospatial statistics were performed on triatomine data, (1) the relative abundance and (2) proportional spatial distribution, from Bahia during two periods: (A) 1957 to 1971 and (B) 2006 to 2019. Results: We observed a decrease in the relative abundance of Panstrongylus megistus (A: n=22.032, 61.9%; B: n=1.842, 1.0%) and Triatoma infestans (A: n=1.310, 3.7%; B: n=763, 0.43%), as well as an increase in the relative abundance of T. sordida (A: n=8.314, 23.4%, B: n=146.901, 81.6%) and T. pseudomaculata (A: n=894, 2.5%, B: n=16.717, 9.3%). Conclusions: Our results indicate a clear reduction in the occurrence of P. megistus and T. infestans (last record in 2015) and an increase in the relative abundance and geographical distribution of T. sordida and T. pseudomaculata after 40 years of the vector-control program. The high frequency of other triatomine species in the municipalities of the state of Bahia and their abundance in recent years highlight the need to reinforce permanent entomological surveillance actions to prevent Chagas disease.

Coccidioidomycosis in Brazil: Historical Challenges of a Neglected Disease.

Coccidioidomycosis is a deep-seated fungal infection that occurs exclusively in semiarid areas in the Americas. In Brazil, coccidioidomycosis occurs exclusively in rural areas in the northeast region and affects counties that are hit by recurrent droughts, poverty and economic stagnation. Since 1978, approximately 136 cases of the disease have been reported in Brazil, according to scientific publications. However, a lack of governmental epidemiological data as well as a similarity to tuberculosis have led scientists and experts to assume that a greater number of cases occur in the country, which are not diagnosed and/or reported. In this review, general characteristics of coccidioidomycosis are presented, followed by a description of the main clinical and epidemiological data of cases in Brazil. The purpose of this article is to discuss the inclusion of coccidioidomycosis in the list of neglected tropical diseases. We believe that the adoption of coccidioidomycosis as a neglected tropical disease will enable the creation of an effective epidemiological surveillance system and the development of feasible public health solutions for its control in vulnerable populations.

Bats in a restinga area in Sergipe, Northeastern Brazil

There is little known about the bats of the Brazilian restinga as most studies have concentrated on the countrys south and southeast regions. In Sergipe, Northeastern Brazil, the only study previously carried out registered 17 species in different restinga habitats. Thus, this study aimed to characterize the bat community in a restinga area in Sergipe and update the list of species that occur in the area. The study was carried out in the Caju Private Natural Heritage Reserve, on the south coast of the state of Sergipe. Monthly campaigns were carried out from October 2016 to September 2017 over two consecutive nights and alternating between two sites to capture the bats. We captured Bats using 10 mist nets that remained open between 6:00 p.m. and 12:00 p.m. We determined the abundance and trophic guilds of the captured species. In addition, we obtained the occurrence frequency degree through the Constancy Index. We captured 457 individuals distributed over 13 species and two families, where three species represented a new record for the locality. The family Phyllostomidae was the richest and most abundant. Most species were frugivorous (61.5%). According to the Constancy Index, only four species were considered common. Using Jackknife 1 estimator, we estimated 14.83 species for the area, indicating that the richness obtained in this study corresponds to 87.6% of this estimate. This study resulted in an 17.6% increase in bat richness known for the area. The high representativeness of the Phyllostomidae family may be related to the capture method used. The predominance of frugivores bats in this study may be associated with the presence of many fruit trees in the area. The low occurrence of species considered common is often reported and can be explained by the species trophic specializations and by the sampling methods. Considering the scarcity of studies in restinga areas in Northeastern Brazil, this work becomes important for the knowledge of the bats in this environment, especially for Sergipe.(AU)

Record of the non-indigenous species Sternaspis aff. nana Zhadan, Tzetlin & Salazar-Vallejo, 2017 (Annelida: Sternaspidae) in the Southwest Atlantic Ocean

The introduction of non-indigenous marine species in new habitats is generally associated with ships arriving at ports, driven by species transported in ballast water and sediment and biofouling communities on ship hulls, drifting object and underwater surfaces in dock areas. The present paper reports the record of the specie Sternaspis aff. nana in the Atlantic Ocean, discussing its possible conservation status and method of arrival to Brazil. Sediments samples were collected in the external area (11 m depth) of the Suape Harbor (Brazil) in February 2018. Two individuals of Sternaspis aff. nana were recorded, representing the first record of this species in the Southwest Atlantic Ocean. The way S. aff. nana arrived in Brazilian waters cannot be easily determined, the short-lived lecithotrophic larvae of sternaspids suggest that the specimens found in Suape have arrived in ballast sediment. An increase in trade between Brazil and Asian countries since the 2000s has led to that more ships coming from China having arrived in Brazilian harbors. The arrival of S. aff. nana, originally described in the South China Sea, in the Suape harbor area may have resulted from this intense movement of ships between China and Brazil.(AU)

The leaf-miner Nemorimyza Frey, 1946 in the Neotropical region: key to species and first record of Nemorimyza posticata (Meigen, 1830) from Brazil (Diptera, Agromyzidae)

ABSTRACT Nemorimyza Frey, 1946 (Diptera, Agromyzidae) is a genus of leaf-miner flies, with only five known species, some potentially polyphagous. Nemorimyza posticata (Meigen, 1830) is recorded from Brazil here for the first time. We provide a diagnosis of this species, including images of the male terminalia. We also provide a key for the five Neotropical species of the genus Nemorimyza, with host and distribution information for each species.

Factors associated with the seroprevalence of caseous lymphadenitis in sheep from Northeastern Brazil.

Caseous lymphadenitis (CL) is one of the main infectious diseases in sheep, responsible for great economic losses, mainly in Northeast region of Brazil, which has the largest sheep flock in the country. Thus, the aim of this survey was to determine the factors associated with the seroprevalence of this disease in sheep from Northeastern Brazil using a planned sample of flocks and animals. Samples were collected from 2312 adult and young sheep of both sex from 196 farms, located in 51 municipalities in five Northeastern Brazilian states (Ceará, Paraíba, Piauí, Rio Grande do Norte, and Sergipe). Serological diagnosis was performed using the indirect ELISA technique. Factors associated with seropositivity were identified by variables extracted from epidemiological questionnaires administered to breeders, using univariable and multivariable analyses. Factors associated with prevalence were purebred sheep (Prevalence ratio - PR = 1.189; P = 0.017), ram acquisition from animal expositions (PR = 1.192; P = 0.020), offspring is separated from ewes (PR = 1.132; P = 0.048), water supplied to sheep from ponds (PR = 1.365; P = 0.002), and delayed disposal of infected animals (PR = 1.263; P = 0.027). Flock-level and animal-level prevalences were 93.88 % (95 % CI = 89.60-96.46%) and 37.46 % (95 % CI = 35.51-39.45%), respectively. In view of the high prevalence found here and based on the associated factors, the implementation of an efficient CL control programme in Northeastern Brazil is recommended.

Retrospective cross-sectional observational study on the epidemiological profile of dengue cases in Pernambuco state, Brazil, between 2015 and 2017.

BACKGROUND: The spread of Dengue virus (DENV) infections, as well as their signs and symptoms, are the result of a complex interaction between several factors. In Brazil, especially in the Northeastern, dengue is an important public health problem. Here, we report an epidemiological analysis of dengue cases in Pernambuco state, Northeastern Brazil, during 2015-2017. METHODS: This work is a retrospective cross-sectional observational study on the epidemiological profile of all dengue cases confirmed and reported to the Health Secretary of Pernambuco between 2015 and 2017. These data cover all municipalities of Pernambuco, except Fernando de Noronha. DENV-positive individuals were classified according to the dengue type (without and with warning signs, or severe dengue), age, gender, ethnicity and intermediate geographic region of residence (Recife, Caruaru, Serra Talhada or Petrolina). The distribution of cases over the years was assessed by χ2 test. Temperature and rainfall data were evaluated by Unpaired t-test. p-value < 0.05 and CI 95% were considered in all analyses. RESULTS: Most dengue cases was without warning signs. The most observed characteristics in the less severe dengue phenotypes were: female, mulatto ethnicity and age between 20 and 39 years old; this profile was more clearly observed in 2015. In 2016 and 2017, however, the numbers of dengue without and with warning signs were more evenly distributed and the difference in cases within groups decreased significantly. Regarding severe dengue, mulattoes were the most affected, but it is possible to note a trend towards a more uniform distribution between the genders and ages. Recife was the region with the highest numbers of both total cases and incidence rates and the highest rainfall levels. Overall, over the years, there has been a decrease in dengue cases in all regions of Pernambuco. CONCLUSIONS: We identified the epidemiological profile of dengue in Pernambuco, Brazil, reporting the gender, age, ethnicity and regions most affected by different dengue types. In addition, we observed that these cases were probably more influenced by rainfall than by temperature. Finally, we believe that this epidemiological knowledge is important to direct public health policies to the reality of each population.
