Environmental Change and Zoonotic Disease Risk at Human-Macaque Interfaces in Bangladesh
This study revealed that local environmental changes, deforestation, urban expansion, construction, and water bodies' disappearance are linked to increasing human-macaque interactions. Understanding these interactions is critical to develop successful mitigation interventions at interfaces with a high risk for viral disease spillover. (Source: EcoHealth)

First Evidence of Akodon-Borne Orthohantavirus in Northeastern Argentina
AbstractOrthohantaviruses (genusOrthohantavirus, familyHantaviridae) are the etiologic agents of Hantavirus Pulmonary Syndrome in the Americas. In South America, orthohantaviruses are highly diverse and are hosted by sigmodontine rodents (subfamiliy Sigmodontinae, family Cricetidae), an also diverse group of rodents. The aims of this work were to (1) identify orthohantavirus hosts and (2) to study the spatial and temporal variations in the prevalence of infection and their associations with community, environmental and individual characteristics, in different environments of Misiones province, northeastern Argentina. Live-...

One Health Implications of Antimicrobial Resistance in Bacteria from Amazon River Dolphins
This study aimed to evaluate the antimicrobial susceptibility of Gram-negative bacteria recovered from two populations of free-ranging Amazon river dolphins (Inia geoffrensis). Twenty-one animals were captured and released, 13 from Negro River and 8 from Tapaj ós River, Brazil. Swab samples were obtained from the oral cavity, blowhole, genital opening and rectum and were cultured on MacConkey agar. Isolates were biochemically identified, and antimicrobial susceptibility was assessed by disk diffusion method. Overall, 132 isolates were recovered, of which 71 were recovered from animals from Negro River and 61 from Tapajós...

Two Novel Adenoviruses in Free-Living British lizards
In this study, we describe two novel adenoviruses isolated from (i) a common lizard (Zootoca vivipara) found dead and examined post-mortem and (ii) pooled samples from free-living sand lizards (Lacerta agilis agilis). Sequencing indicated the two were closely related atadenovirus strains which were distinct from previously recorded adenoviruses in lizards. Adenoviruses are not always associated with disease in squamates, but morbidity and mortality have been reported. These are the first known cases of adenovirus infection in free-living native British lizards, and further monitoring will be necessary to elucidate the impl...

Temporal Trends in Antimicrobial Resistance of Fecal Escherichia coli from Deer
In this study, we characterize the phenotypic resistance of commensalEscherichia coli from fecal samples of 879 individual white-tailed (Odocoileus virginianus; WTD) over a ten-year period and analyze resistance patterns. Our results show commensalE. coli from WTD had significant linear increases in reduced susceptibility to 5 of 12 antimicrobials, including broad-spectrum cephalosporins and fluoroquinolones, from 2006 to 2016. In addition, the relative frequency distribution of minimal inhibitory concentrations of two additional antimicrobials shifted towards higher values from across the study period. The prevalence of m...

Invasive Plants as Foci of Mosquito-Borne Pathogens: Red Cedar in the Southern Great Plains of the USA
This study tested the hypotheses that mosquito communities and their likelihood of WNV infection differ between ERC and other habitats in the southern Great Plains of the United States. We found support for our first hypothesis, with significantly moreCulex tarsalis andCulex erraticus in ERC than deciduous and grass habitats. Mosquito communities in Central Oklahoma were more diverse (21 species) than western Oklahoma (11 species) but this difference was not associated with vegetation. Our second hypothesis was also supported, with significantly more WNV-infectedCulex from ERC in both regions, as was our third hypothesis, ...

Seasonality of Date Palm Sap Feeding Behavior by Bats in Bangladesh
We described the frequency of bat visits, duration of bat visits, and duration of bat-sap contact by month and by year. We captured 42,873 bat visits during 256 camera-nights of observation, of which 3% werePteropus and 94% were non-Pteropus bats. Though the frequency ofPteropus bat visits to each tree/night was much lower than non-Pteropus bat visits,Pteropus bats stayed in contact with sap longer than non-Pteropus bats. Frequency of bat visits was higher during winter compared to other seasons, which may arise as a consequence of limited availability of food sources during this period or may be related to seasonal charac...
