Isolation and Identification of Fungal Strains from Fresh and Smoked Fish from the Sassandra River in Côte d’Ivoire

Introduction: Fresh and smoked fish are widely consumed in Côte d'Ivoire as everywhere in West Africa. However, these foodstuffs, due to certain processing conditions, are likely to be contaminated by molds that produce dangerous mycotoxins. Objective: This study aimed to isolate and identify fungal strains contaminating fresh and smoked fish from the Sassandra River in Côte d'Ivoire. Place and Date of the Study: Sampling was carried out in various processing sites around the Sassandra River, particularly in the towns of Soubré and Guessabo. The microbiological analysis was carried out at Jean Lorougnon Guédé University in Daloa (Ivory Coast). Methods: A total of 108 samples of fresh and smoked fish were collected. Isolation and purification of fungal strains were carried out on Sabouraud medium with chloramphenicol. The identification of isolated strains was made on the basis of morphological and cultural criteria. Results: A total of 126 fungal strains were isolated, including 87 from the Guessabo samples and 39 from the Soubré samples from 54 fresh fish and 54 smoked fish. The predominant species were Aspergillus of the Glaucus group (39%), Aspergillus niger (36%) and Penicillium sp. (25%). Conclusion: This study shows that fresh and smoked fish from the Sassandra River in Côte d'Ivoire are contaminated by several strains of molds, some of which produce mycotoxins that can cause illness in consumers depending on their concentrations. It would therefore be appropriate to improve processing techniques.

IDENTIFYING THE ECOTOURISM SUITABILITY SCORE FOR MARINA BEACH AND ELLIOT'S BEACH OF CHENNAI COAST, TAMIL NADU, INDIA.

At the Chennai Coast in Tamil Nadu, India, research is done. Finding out whether Marina Beach and Elliott's Beach are suitable for ecotourism is the study's main goal. For the research using the ecotourism suitability index methodology, land use, land cover, erosion, accretion, beach type, beach width, proximity to bus stop, proximity to train station, and suspended sediment load have all been taken into account. The suitability index of eco tourism is assigned into 4 (four) classes, which are: Class S1 (Highly suitable), Class S2 (Quite Suitable), Class S3 (Suitable with condition) and Class N (Not Suitable). Result of analysis indicates that coast area of Marina Beach and Elliots beach area comes in the class of Highly suitable (S1) by score total of 129 or 95.5 % and 116 or 85.9 % respectively. According to the research, Marina Beach has a sand feature as a land use land cover, 213 metres of beach width, good clarity (500 mg/L), is located 361 metres from a bus stop and 681 metres from a train station, has moderate erosion, and has not experienced any accretion. The beach type is white sand. Likewise, Elliots Beach has a sand feature as a land use land cover, with 222 metres of beach width, good clarity (600 mg/L), 642 metres from the bus stop, and 2351 metres from the railway station, which is high. There is moderate erosion and no accretion, and the sand is of the beach type, which is white. Marina beach has high tourism suitability index as compared to Elliot's beach. By considering marina beach, all the eight parameters are considered to be ne whereas Elliot's beach has far away accessibility this is the main reason for lowering the tourism suitability.

Dépistage de la stéatose hépatique par le Fibroscan/CAP chez les sujets noirs africains porteurs d'une Hépatite Virale B chronique en Côte d'Ivoire / Fibroscan/CAP screening for hepatic steatosis in black African subjects with chronic Viral Hepatitis B in Ivory Coast

Context and objectives As the global epidemic of obesity and metabolic syndrome progresses, the coexistence of fatty liver disease in patients with chronic viral hepatitis B (VHB) becomes significant. The objective of this work was to determine the frequency of hepatic steatosis assessed by Fibroscan/CAP (Controlled Attenuation Parameter) in patients with chronic VHB in Côte d'Ivoire. Methods. The study included 83 patients with chronic VHB. These were black patients who had performed a Fibroscan/CAP during the recruitment period and were willing to participate in the study. Patients with significant alcohol consumption, a secondary cause of hepatic steatosis, another liver disease regardless of the etiology associated with VHB were not included. Results. The frequency of hepatic steatosis in chronic HBV carriers assessed by CAP in our study population was 48.19 %, including 24.10 % of severe steatosis. Obesity was statistically correlated with the presence of steatosis in our patients. Patients who had steatosis on ultrasound were 5 times more likely to have steatosis on CAP. Significant fibrosis was insignificantly associated with steatosis. Conclusion. The frequency of fatty liver disease detected by fibroscan/CAP is high in patients with chronic VHB.

Contexte et objectifs Avec la progression de l'épidémie mondiale d'obésité et du syndrome métabolique, la coexistence d'une stéatose hépatique chez les patients porteurs d'une hépatite virale B chronique devient non négligeable. L'objectif de ce travail était de déterminer la fréquence de la stéatose hépatique chez les patients porteurs d'une hépatite virale B (HVB) chronique. Méthodes. Il s'agissait d'une série des cas de HVB de race noire, ayant réalisé un Fibroscan/CAP pendant la période du recrutement et consentants à participer à l'étude. Les patients ayant une consommation d'alcool significative, une cause secondaire de stéatose hépatique, une autre hépatopathie quelle que soit l'étiologie associée à l'hépatite B n'ont pas été inclus. Résultats. Quatre-vingt-trois patients porteurs d'une HVB ont été inclus. La fréquence de la stéatose hépatique chez les porteurs du VHB chronique était de 48,19 % dont 24,10 % de stéatose sévère. L'obésité était statistiquement corrélée à la présence d'une stéatose chez nos patients. Les patients qui avaient une stéatose à l'échographie étaient 5 fois plus à risque d'avoir une stéatose au CAP. La fibrose significative était associée de façon non significative à la stéatose. Conclusion : Près de la moitié des patients porteurs d'une hépatite virale B chronique présente une stéatose hépatique.

Biodiversity of commercially important finfish species caught by mid-water and bottom trawls from two different coasts of Arabian Sea: Threats and conservation strategies / Biodiversidade de espécies de peixes comercialmente importantes capturadas por redes de arrasto de médio e fundo do Baluchistão e costas de Sindh do mar da Arábia no Paquistão: Ameaças e estratégias de conservação

Abstract This study was conducted to estimate the diversity and the occurrence of commercially important finfish species collected by twenty fish sampling site of Sindh and Baluchistan coasts of the Arabian Sea in Pakistan from January to December 2019. Additionally, physicochemical characteristics of seawater were analyzed from these selected sites and found to be within suitable ranges required for fish growth and survive. A total of 81287 fish individuals were collected and identified as 49 species belonging to 26 families in our study. The most diversified family was Sparidae (13 species) followed by Carangidae and Lutjanidae (4 species), Mullidae, Serranidae, Ariidae (3 species), and Sciaenidae (2 species). The remaining 20 families were represented by only one species. The values of Shannon diversity index calculated for the four selected habitats revealed that high fish diversity was reported at Sonmiani Coast (H'=1.81), while less at Ormara Coast (H'=0.23). Likewise, Evenness index (E) was high at Sonmiani Coast (E=0.50) and less fish diversity was reported at Ormara Coast (E=0.06). Reducing risks to threatened marine species in coastal habitats also requires conservation actions at multiple scales. Thus, it was concluded that our study could be valuable in providing the more information's regarding to the diversity of finfish species and their occurrence along the Pakistan Coast. Further, to better understand the effects, regular monitoring and conservation measures should be taken to mitigate the influence of anthropogenic activities and protect finfish diversity from further decline

Resumo Este estudo foi conduzido para estimar a diversidade e a ocorrência de espécies de peixes comercialmente importantes coletadas por vinte locais de amostragem de peixes nas costas de Sindh e Baluchistão do mar da Arábia, no Paquistão, de janeiro a dezembro de 2019. Além disso, as características físico-químicas da água do mar foram analisadas a partir desses peixes locais selecionados e considerados dentro dos intervalos adequados necessários para o crescimento e sobrevivência dos peixes. Um total de 8.1287 indivíduos de peixes foi coletado e identificado como 49 espécies pertencentes a 26 famílias em nosso estudo. A família mais diversificada foi Sparidae (13 espécies), seguida por Carangidae e Lutjanidae (4 espécies), Mullidae, Serranidae, Ariidae (3 espécies) e Sciaenidae (2 espécies). As 20 famílias restantes foram representadas por apenas uma espécie. Os valores do índice de diversidade de Shannon calculados para os quatro habitats selecionados revelaram que uma alta diversidade de peixes foi relatada na costa Sonmiani (H' = 1,81), enquanto menos na costa Ormara (H' = 0,23). Da mesma forma, o índice de regularidade (E) foi alto na costa de Sonmiani (E = 0,50) e menos diversidade de peixes foi relatada na costa de Ormara (E = 0,06). A redução dos riscos para as espécies marinhas ameaçadas em habitats costeiros também requer ações de conservação em várias escalas. Assim, concluiu-se que nosso estudo pode ser valioso para fornecer mais informações sobre a diversidade de espécies de peixes finos e sua ocorrência ao longo da costa do Paquistão. Além disso, para compreender melhor os efeitos, medidas regulares de monitoramento e conservação devem ser tomadas para mitigar a influência das atividades antropogênicas e proteger a diversidade de peixes finos de um declínio maior.

Morphological Diversity of Fungal Strains Responsible for Dessert Banana Rot, Musa Sapientum (Musaceae) Produced in the South Comoe Region on Ivory Coast

Aims: The banana dessert grown in different regions of the world, encounters important difficulties that cause it to lose its marketability especially because of the diseases related to conservation. The objective here is to identify the strains responsible for fungal diseases of bananas when it is stored. Study Design: This study was undertaken in order to ensure the competitiveness of the dessert banana from Ivory Coast on the international market which is threatened by the recurrent problem of post-harvest rot. Place and Duration of Study: Agrovalorisation Laboratory, Agroforestry Training and Research Unit, Université Jean Lorougnon GUEDE Daloa Côte d'Ivoire, between February 2021 and March 2022. Methodology: The study involved 120 bananas divided into two batches of 10 hands each, one with signs of necrosis and the other with no signs. Banana fragments (crown, epicarp and explant) were deposited on the growing media at several distinct points and slightly embedded in the agar. The resulting colonies were transplanted successively until a pure strain was obtained from a single mushroom colony per petri dish. Results: A total of 11 different genera were identified from 105 isolates. 57 are from necrotic bananas and 36 from bananas with no signs of necrosis. Fungal strains isolated there are: Trichoderma sp. (15%), Fusarium sp. (1%), Scytalidium sp. (39%), Mucor sp. (1%), Scopulariopsis sp. (1%), Alternaria sp. (4%), Aureobasidium sp. (1%), Aspergillus of the Glaucus group (10%), Cladosporium sp. (2%), Pseudallescheria sp. (6%) and Chrysosporium sp. (20%). No strains of the genus Colletotrichum musea responsible for anthracnose that can develop on both green and ripe fruit have been isolated. However, morphological characterization has not among to identify several other species (12) especially those not sporulating. Conclusion: This diversity of isolated strains in this work is identical to that most frequently isolated and cited in the literature.

Efecto de los incendios en la cobertura vegetal, almacenamiento de carbono y biomasa vegetal de un humedal costero / Effect of fires on vegetation cover, carbon storage and plant biomass in a coastal wetland

Resumen Introducción: Los humedales se encuentran entre los ecosistemas más productivos, pero actualmente están siendo degradados o eliminados a un ritmo acelerado por múltiples actividades antrópicas. En la costa central de Perú, los humedales sufren incendios recurrentes, y los efectos poco estudiados incluyen el nivel de emisiones y el secuestro de carbono por quema. Objetivo: Estimar el carbono en la biomasa aérea afectada por el fuego y el carbono recuperado por la vegetación al cabo de un año. Métodos: Trabajamos en el humedal costero Los Pantanos de Villa (Lima, Perú) y comparamos áreas quemadas (32 cuadrantes, 1 m2) y no afectadas (33 cuadrantes). Resultados: La vegetación afectada fue predominantemente herbácea y dominada por Phragmites australis, Schoenoplectus americanus, Typha dominguensis y Cladium jamaicense. El incendio afectó 1 147.0 t de biomasa vegetal que almacenó 381.8 t de carbono, generando la emisión de 1 397.1 t de CO2 a la atmósfera. Al cabo de un año se había recuperado el 79 % de la cobertura vegetal, pero solo el 26 % de la biomasa vegetal viva y el 12.8 % del carbono contenido en la vegetación. Conclusiones: Los indicadores apropiados de la resiliencia de los humedales al fuego deben considerar que los humedales afectados por el fuego recuperan rápidamente la cobertura vegetal, pero no el almacenamiento de carbono y la biomasa vegetal.

Abstract Introduction: Wetlands are among the most productive ecosystems, but currently are being degraded or eliminated at accelerated rates by multiple anthropic activities. In the central coast of Peru, wetlands suffer recurring fires, and the little-studied effects include the level of emissions and carbon sequestration by burning. Objective: To estimate carbon in aerial biomass affected by fire, and carbon recovered by the vegetation after one year. Methods: We worked in Los Pantanos de Villa (Lima, Peru) coastal wetland and compared burnt (32 quadrants, 1 m2) and unaffected areas (33 quadrants). Results: The vegetation affected was predominantly herbaceous and dominated by Phragmites australis, Schoenoplectus americanus, Typha dominguensis and Cladium jamaicense. Fire affected 1 147.0 t of plant biomass that stored 381.8 t of carbon, generating the emission of 1 397.1 t of CO2 into the atmosphere. After one year, 79 % of the vegetation cover had recovered, but only 26 % of the plant biomass and 12.8 % of vegetation carbon. Conclusions: Appropriate indicators of wetland fire resilience should consider that fire-impacted wetland rapidly recovers plant cover, but not carbon storage and plant biomass.

First report of fibropapillomatosis (FP) and Chelonid alphaherpesvirus 5 (ChHV5) in a green sea turtle (Chelonia mydas) from the historically fibropapillomatosis-free Fernando de Noronha Archipelago, Northeastern Brazil / Primeiro caso de fibropapilomatose (FP) e de Chelonid alphaherpesvirus 5 (ChHV5) em tartaruga-verde (Chelonia mydas) no Arquipélago de Fernando de Noronha, Nordeste do Brasil

Fibropapillomatosis (FP) is an infectious disease caused by Chelonid alphaherpesvirus 5 (ChHV5). Nevertheless, its clinical manifestations are considered multifactorial. Due to its relevance, FP is currently monitored in sea turtle populations in the United States, Australia, Caribbean, and Brazil. Between 2000 and 2020, the TAMAR Project/ TAMAR Project Foundation analyzed the prevalence of FP in nine states and oceanic islands along the Brazilian coast, including Fernando de Noronha Archipelago (FNA), a historically FP-free area. A total of 4,435 green sea turtles (Chelonia mydas) were monitored from 2010 to 2016. Additionally, in 2012 and 2014, 43 FP-free skin samples were analyzed for ChHV5 using a qualitative PCR for the UL30 polymerase (pol) sequence. In 2015, a bilateral ocular nodule characterized as an FP tumor was reported in one of the monitored individuals undergoing rehabilitation. Tissue samples were collected following surgical removal of the tumor. Characterization of a 454 bp UL30 polymerase gene revealed a ChHV5 sequence previously reported in other areas of the Atlantic Brazilian coast. In the years following this finding from January 2017 to March 2020, a total of 360 C. mydas were monitored in the same area and no FP tumors were detected. This is the first report of FP and the first detection of ChHV5 in FNA, a finding of great concern considering this site's historical absence of FP occurrence. This study highlights the importance of monitoring this disease in historically FP-free areas of the Brazilian Atlantic coast.(AU)

A fibropapilomatose (FP) é uma doença infecciosa causada pelo Chelonid alphaherpesvirus 5 (ChHV5). No entanto, as manifestações clínicas da doença são consideradas multifatoriais. Esta doença é monitorada atualmente em populações de tartarugas marinhas nos EUA, Austrália, Caribe e Brasil. Desde 2000, o Projeto TAMAR/Fundação Projeto TAMAR analisa a presença de FP em nove estados da costa brasileira e ilhas oceânicas, incluindo o arquipélago de Fernando de Noronha, uma área historicamente livre de FP. Um total de 4.435 indivíduos de Chelonia mydas foram monitorados de 2010 a 2016 e 43 amostras de pele foram analisadas para detectar ChHV5 em 2012 e 2014 com o objetivo de avaliar a presença do vírus em tecidos sem FP, usando uma PCR qualitativa para detecção de sequências do gene da UL30 polimerase. Em 2015, uma tartaruga verde (C. mydas) foi relatada com um nódulo ocular bilateral caracterizado como FP. Amostras de tecido foram coletadas durante sua reabilitação e procedimento cirúrgico para remover o tumor. A caracterização parcial de uma sequência de 454 bp do gene UL30 polimerase detectou ChHV5 anteriormente relatado em outras áreas da costa atlântica brasileira. Após estes achados, de janeiro de 2017 a março de 2020, um total de 360 indivíduos de C. mydas foram monitorados e nenhum caso de FP foi registrado. Este é o primeiro relato de FP e a primeira caracterização de ChHV5 no arquipélago de Fernando de Noronha, uma questão preocupante e que ressalta a importância do monitoramento desta doença em áreas historicamente livres de FP na costa atlântica brasileira.(AU)

Estrategias de afrontamiento ante la crisis sanitaria: un estudio comparativo en enfermeros de costa y sierra ecuatoriana / Coping strategies in the face of the health crisis: A comparative study in nurses from the Ecuadorian coast and highlands

Se realizó una encuesta transversal de dos muestras separadas por conveniencia de enero a marzo de 2021 a fin de comparar la prevalencia de percepción de riesgo e identificar diferentes estrategias de afrontamiento en enfermeros de la costa y la sierra ecuatoriana. Las muestras incluyeron dos grupos de profesionales de enfermería para un total de 518. El 49,0% (n= 254) de los participantes laboraban en la sierra ecuatoriana y el 50,8% (n= 263) prestaban sus servicios en la costa ecuatoriana. Muestreados provenientes de varias clínicas, tanto en la costa como en la sierra ecuatoriana, fueron abordados aleatoriamente por el entrevistador para participar en el estudio. Se examinaron y compararon los resultados de las pruebas de las tres muestras. Los grupos se eligieron en función de la conveniencia del muestreo y la supuesta conciencia de los factores de riesgo de COVID-19. En cuanto a la percepción de riesgo, su prevalencia es significativamente mayor para las enfermeras de la costa que las de la sierra. Las enfermeras que prefieren trabajar en equipo durante la crisis sanitaria tenían probabilidades alrededor de 0,30 más bajas, lo que puede interpretarse como un factor protector. Respecto al miedo al contagio no se hallaron diferencias entre enfermeras de la costa o la sierra(AU)

A cross-sectional survey of two samples separated by convenience was carried out from January to March 2021 to compare the prevalence of risk perception and identify different coping strategies in nurses from the Ecuadorian coast and highlands. The samples included two groups of nursing professionals for a total of 518. 49.0% (n= 254) of the participants worked in the Ecuadorian highlands and 50.8% (n= 263) provided their services on the ecuadorian coast. Samples from various clinics, both on the coast and in the Ecuadorian highlands, were randomly approached by the interviewer to participate in the study. The test results of the three samples were examined and compared. Groups were chosen based on sampling convenience and presumed awareness of COVID-19 risk factors. Regarding the perception of risk, its prevalence is significantly higher for nurses from the coast than those from the mountains. Nurses who prefer to work in a team during the health crisis had probabilities around 0.30 lower, which can be interpreted as a protective factor. Regarding the fear of contagion, no differences were found between nurses from the coast or the mountains(AU)

Factors affecting family medicine programmes in Sub-Saharan Africa: a narrative review of recent literature

Objectives: This study sought to assess the level of anti-glycaemic medication-taking and its predictors among adults living with diabetes receiving treatment at Cape Coast Teaching Hospital (CCTH). Design: This was a cross-sectional study carried out among adults living with diabetes and receiving care at CCTH. Data on socio-demographic characteristics and anti-glycaemic medication-taking were gathered using a structured questionnaire. A scale consisting of 4 domains (filling prescribed medication; taking medications appropriately ac-cording to the instructions of healthcare professionals; practising behavioural modifications, and showing up for fol-low-up appointments) and eight items was used to measure the level of anti-glycaemic medication-taking. Descriptive statistics, chi-square test (and Fisher's exact test where appropriate), bivariate and multivariate logistic regression models were used in analysing the data. Setting: The study was carried out in the diabetes clinic in Cape Coast Teaching Hospital. Participants: The total enumerative sampling technique was used to select 250 adults living with diabetes and receiv-ing care at CCTH.Main outcome measures: Anti-glycaemic medication-taking Results: Out of 250 participants studied, 42% had high anti-glycaemic medication-taking. Predictors of anti-glycae-mic medication-taking included; forgetfulness (aOR=0.02, 95% CI: 0.00-0.64, p<0.001), patient's involvement in treatment plan (aOR=0.12, 95% CI: 0.02-0.64, p=0.014) and having good knowledge about one's medication (aOR=2.34, 95% CI: 1.10-4.98, p=0.028). Conclusion: Less than half of the sample population (42%) had high anti-glycaemic medication-taking, with forget-fulness, involvement in the treatment plan and good knowledge about anti-glycaemic medications, predicting medi-cation-taking

Distribution and abundance of dinoflagellates from the coastal waters of Karachi, Pakistan, northern part of the Arabian Sea / Distribuição e abundância de dinoflagelados nas águas costeiras de Karachi, Paquistão, parte norte do Mar da Arábia

The present study reports on seasonal and spatial variations in diversity, distribution and abundance of dinoflegellates and indicates the presence of HAB species in Pakistan waters. A total of 179 taxa, recorded in this study from offshore and near-shore waters, belong to 41 genera in 26 families and 10 orders. The high species count (149 species) was recorded from Manora Island offshore station (MI-1) and 105 spp, 109 spp and 115 spp were encountered from the Mubarak village offshore station (MV-1), Manora near shore station (MI-2) and Mubarak Village near-shore station (MV-2) respectively. Tripos furca was the dominant and frequently occurring species (> 1 x103 to > 25 x103 cells L-1 from coastal and >1x 105 cells L-l from near-shore stations) in addition to less abundant Alexandrium catenella, Alexandrium sp., Alexandrium minutum, and Prorocentrum micans (>103 to 25x 103cells/L). Another 44 species occurred in relatively low numbers (<103 cell L-l). Seventy species were found throughout the study period at all four stations. High number of species in three genera (Tripos (38), Protoperidinium (34) and Prorocentrum (20) was recorded. Potently toxic (16 genera 43 species) and HAB related (19 genera and 30 species) dinoflagellate taxa were also recorded. The percent contribution of dinoflagellates in total phytoplankton population generally remained below 20% except for a few instances. Manora Island stations had comparatively higher Shannon index and equitability and slightly lower dominance index. The PCA plot showed strong positive correlation among chlorophyll-a concentration, dissolved oxygen, total number of phytoplankton and dinoflagellates.

Perfil epidemiológico das parasitoses intestinais em moradores de uma comunidade da Ilha de Boipeba, Bahia, Brasil / Epidemiological profile of intestinal parasites in residents of a community on the island of Boipeba, Bahia, Brazil

Introdução: as parasitoses intestinais constituem-se um importante problema de saúde pública mundial. Estas infecções são mais prevalentes em regiões tropicais impactando na morbimortalidade e aumento nos custos para o sistema de saúde. Objetivo: avaliar a prevalência das enteroparasitoses e sua associação com as condições socioeconômicas, sanitárias, ambientais e hábitos de vida em uma comunidade costeira do Nordeste brasileiro. Metodologia: estudo epidemiológico, descritivo e transversal, realizado de modo não probabilístico entre março a junho de 2017, com 105 moradores da Ilha de Boipeba, localizada no Sul da Bahia. O exame parasitológico de fezes foi realizado pelos métodos de sedimentação espontânea, Baermann-Moraes e FAUST. Um questionário foi aplicado para avaliar o perfil sociodemográfico da população. Resultados: do total de indivíduos avaliados, 52,4% eram do sexo feminino e 57,1% tinham entre 15 a 59 anos. Todos os indivíduos possuíam água encanada, porém não tratada, enquanto 91,4% referiu ingerir vegetais crus e 45,7% não higienizavam as mãos antes as refeições. Sintomas gastrointestinais foram relatados em 82,8% dos indivíduos e infecções enteroparasitárias foram diagnosticadas em 69,6%. Os parasitos mais frequentemente encontrados foram Ancilostomídeo (18,1%) e Entamoeba coli (43,8%). O principal fator de risco potencial para contrair a infecção por ancilostomídeos foi a não existência de poço artesiano na residência (RP=4,35), enquanto para Trichuris trichiura foi não dispor de pia no banheiro (RP=3,82). Conclusão: a comunidade analisada apresentou elevada prevalência de enteroparasitoses. Os hábitos precários de higiene e de acesso à água tratada, associados às condições ambientais e climáticas do local, podem ter contribuído para a elevada transmissão de geohelmintos observada.

Introduction: Intestinal parasitic infections are an important public health problem worldwide. They are more prevalent in tropical regions impacting in morbidity and mortality and costs for the health system. Objective: To evaluate the prevalence of enteroparasitosis and its association with socioeconomic, sanitary and environmental conditions and lifestyle habits in a coastal community in the Northeast Brazil. Methodology: This is an epidemiological, descriptive and cross-sectional study, carried out in a non-probabilistic manner between March and June 2017, with 105 residents of Boipeba Island in the Southern Bahia. The parasitological examination of feces was carried out by the methods of spontaneous sedimentation, Baermann-Moraes and FAUST. A questionnaire was applied to assess the sociodemographic profile of the population. Results: Of the total of individuals evaluated, 52.4% were female and 57.1% were between 15 and 59 years old. All individuals had piped, but untreated water, while 91.4% reported eating raw vegetables and 45.7% did not wash their hands before meals. Gastrointestinal symptoms were observed in 82.8% individuals and 69.6% were diagnosed with enteroparasitic infections. The most frequent parasites were the hookworm (18.1%) and Entamoeba coli (43.8%). The main potential risk factor for hookworm infection was the non-existence of an artesian well in the residence (PR=4.35) and Trichuris trichiura it was not having a sink in the toilet (PR=3.82). Conclusion: The analyzed community has a high prevalence of enteroparasitosis, in addition to environmental and climatic conditions that contribute to the transmission of these infections.

First assessment about the phlebotomine fauna (Psychodidae: Phlebotominae) of Atlántico department from Colombia / Primera aproximación a la fauna flebotomínea (psychodidae: phlebotominae) del departamento de atlántico

RESUMEN Dentro del género Lutzomyia algunas especies son vectores de la enfermedad llamada leishmaniasis, la cual tiene implicaciones en la salud pública, desarrollando diferentes manifestaciones clínicas como leishmaniasis cutánea, visceral y mucocutánea que afectan altamente al ser humano. El objetivo de este estudio fue realizar un inventario de las especies del género Lutzomyia presentes en seis zonas del departamento del Atlántico. Se implementaron tres técnicas de capturas tradicionales: trampas CDC entre 18:00-06:00, trampa Shannon entre 19:00-22:00 y búsqueda activa de flebotomíneos con aspiradores bucales en troncos, bases de árboles y otros sitios entre 09:00-11:00 y 16:00-17:30, en seis municipios del departamento del Atlántico, Colombia. Se capturaron diez especies flebotomíneas y se reporta por vez primera para el departamento del Atlántico el hallazgo de Lutzomyia longipalpis y Lutzomyia atroclavata. De las diez especies capturadas, Lutzomyia longipalpis tiene antecedentes como vector de Leishmania infantum en Colombia y en otras regiones de Latinoamérica, además es considerada el principal vector de leishmaniasis visceral en las Américas. La especie más abundante y con mayor distribución espacial fue Lu. evansi, principal vector de leishmaniasis visceral en la región Caribe. En conclusión, la riqueza de la fauna flebotomínea del departamento de Atlántico se actualiza a doce especies, con el primer registro de Lu. longipalpis y Lu. atroclavata. También se reporta la fauna flebotomínea por primera vez en localidades del departamento de Atlántico como Campeche, Puerto Colombia, Luruaco, Ponedera y Campo de la Cruz.

ABSTRACT The genus Lutzomyia has a variety of species, where some are vectors of the disease called leishmaniasis which has implications for public health developing different clinical manifestations that highly affect humans such as cutaneous, visceral and mucocutaneous leishmaniasis. The aim of the study was to update the registry of the Lutzomyia species that are present in six areas of the Atlántico department. Three traditional capture techniques were implemented, with CDC traps implemented from 18:00 to 6:00 o'clock, Shannon traps from 19:00 to 10:00 and active search with mouth aspirators on trunks, tree bases and other rest sites from 09:00 to 11:00 and 16:00 to 17:30, in six municipalities of the Atlántico department, Colombia. Ten phlebotomine species were captured during the present work, from which the finding of Lutzomyia longipalpis and Lutzomyia atroclavata are reported for the first time at the Atlántico department. From the ten species captured, Lutzomyia longipalpis has antecedents as a vector of Leishmania infantum in Colombia and other regions of Latin America. The most abundant species with the greatest spatial distribution was Lu. evansi, which is the main vector of visceral leishmaniasis in the Caribbean region. In conclusion, the richness of phlebotomineal fauna of the department of Atlántico is updated to twelve species, with the first record of Lu. longipalpis and Lu. atroclavata. Phlebotomy fauna is also reported for the first time in localities of the department of Atlántico such as Campeche, Puerto Colombia, Luruaco, Ponedera and Campo de la Cruz.

Trabajos originales Mamíferos pequeños de humedales de la costa central del Perú / Small mammals from central Peruvian coast wetlands

Resumen Los humedales son ecosistemas frágiles e importantes que, a pesar de su gran biodiversidad, se conoce poco sobre la diversidad de mamíferos. Por ello, en este estudio se documenta la diversidad y abundancia de los mamíferos pequeños de cuatro humedales de la costa central peruana: Albufera de Medio Mundo, Refugio de vida silvestre Pantanos de Villa, Ensenada San Antonio y Caucato. Se realizó una evaluación convencional con trampas y redes, complementada con el método acústico. El esfuerzo de muestreo fue de 4651 trampas/noche, 145 redes/noche y 48 horas/detector. Registramos 5 especies nativas de roedores, 3 roedores introducidos, 12 murciélagos y un marsupial. El roedor Akodon mollis y los murciélagos Nyctinomops laticaudatus y N. macrotis son primeros registros para el departamento de Lima. El cuy silvestre se distribuye en el centro y sur de la costa y confirmamos la presencia del marsupial Didelphis pernigra a nivel del mar. La mayoría de los humedales están fuertemente impactados por la alta abundancia relativa de roedores introducidos, especialmente de Mus musculus y Rattus rattus. La diversidad β fue moderada a pesar de la relativa cercanía entre los humedales. Resaltamos la alta diversidad de mamíferos pequeños nativos en los humedales y alertamos sobre el impacto que los roedores introducidos pueden producir sobre la sobrevivencia de las demás especies. Además, hipotetizamos que la fauna nativa aquí reportada estuvo presente en la región de Lima al menos todo el periodo republicano. Estos humedales requieren protección continua, monitoreo e implementación de medidas de restauración para asegurar la conservación de su biota.

Abstract Wetlands are fragile, unique and important ecosystems that harbour great biodiversity. However, mammalian diversity in wetlands along the Peruvian coast is poorly known. We present data on the diversity and abundance of small mammals from four wetlands located on the central Peruvian coast: Albufera de Medio Mundo, Pantanos de Villa Wildlife Refuge, Ensenada San Antonio, and Caucato. We used conventional traps to survey rodents and mist nets combined with acoustic recording methods to survey bats. Our sampling effort totalled 4651 traps/night, 145 nets/night, and 48 hours/detector. We recorded 5 native species of rodents, 3 non-native rodents, 12 species of bats, and one marsupial. The rodent Akodon mollis and the bats Nyctinomops laticaudatus and N. macrotis are the first records for the department of Lima. The wild guinea pig is distributed along the central and southern Peruvian coast, and the presence of the Andean White-eared Opossum, Didelphis pernigra, at sea level is confirmed. The majority of wetlands we surveyed are highly impacted by non-native species, notably Mus musculus and Rattus rattus which have a high relative abundance in Pantanos de Villa and Caucato. β diversity among the four wetlands is moderate despite the relatively short distance between them. We highlight the high diversity of small native mammals in coastal wetlands and warn about the harmful impact the high relative abundance of introduced rodents can produce on the survival of native species. Furthermore, we hypothesized that native fauna reported here was present in Lima region at least throughout the Republican period. These wetlands require continuous protection, monitoring and implementation of restoration measures to ensure the conservation of their biota.

Fish community structure as an indicator of the ecological significance: A study from Ulhas River Estuary, Western coast of India

Aim: The present study was aimed to analyze the ecological significance of Ulhas River estuary of the western coast of India using the taxonomic, functional and conservation aspects, and also to record an updated data base on the estuarine community structure.Methodology: Ichthyo faunal diversity was assessed by experimental fishing conducted at 3 selected stations using single day dolnets of code end mesh size of 10mm, from September 2017 to August 2018. The diversity of fish species was recorded considering the most relevant taxonomic classification data and further supplemented by the information pertaining to ecological roles played by the individual species (using guild approach) and the IUCN- conservation status. Results: There were 105 species, belonging to 4 classes, 19 orders, 44 families and 75 genera, recorded from Ulhas River Estuary. The class: Actinopterygii was the most diverse taxa, (including 12 orders, 32 families and 55 genera) among the total ichthyofauna reported. Order Perciformes was the most representative order of the class (40 species, 31 genera and 17 families), followed by Decapoda (21species, 8 genera and 6 families). Based on the estuarine usefunctional guild categorization, 51.42 % of the species were marine migrants, followed by amphidromous species (21.9%). Zoobenthivores (29.41%) was found to be the most dominant feeding guild followed by omnivores (19.6%). Based on the IUCN Red List, 53.33% of the fish species observed from Ulhas River Estuary were categorized as “Not Evaluated”, and 7% were “Data Deficient”, signifying the lack of information on biological aspects of the species along Indian waters. Tenualosa toli marked its presence under threatened category (Vulnerable) from Ulhas River Estuary. Interpretation: The abundance of marine migrants as well as the amphidromous species in the estuary signifies the use of this ecosystem for the nursery function of commercially important marine fisheries resources. Increased proportion of “Not Evaluated” and “Data Deficient” categories in the context of high level of anthropogenic stress demands for more updated documentation of the biodiversity and periodic changes in its ecological structure for formulating and implementing effective ecosystem-based management programs for such sensitive estuarine ecosystems.
