Abstract
Bats are important hosts of zoonotic viruses with pandemic potential, including filoviruses, MERS-Coronavirus (CoV), SARS-CoV -1, and likely SARS-CoV-2. Viral infection and transmission among wildlife are dependent on a combination of factors that include host ecology and immunology, life history traits, roosting habitats, biogeography, and external stressors. Between 2016 and 2018, four species of insectivorous bats from a readily accessed roadside cave and buildings in Ethiopia were sampled and tested for viruses using consensus PCR assays for five viral families/genera. Previously identified and novel coronaviruses and paramyxoviruses were identified in 99 of the 589 sampled bats. Bats sampled from the cave site were more likely to test positive for a CoV than bats sampled from buildings; viral shedding was more common in the wet season; and rectal swabs were the most common sample type to test positive. A previously undescribed alphacoronavirus was detected in two bat species from different taxonomic families, sampling interfaces, geographic locations, and years. These findings expand knowledge of the range and diversity of coronaviruses and paramyxoviruses in insectivorous bats in Ethiopia and reinforce that an improved understanding of viral diversity and species-specific shedding dynamics is important for designing informed zoonotic disease surveillance and spillover risk reduction efforts.
期刊介绍:
EcoHealth aims to advance research, practice, and knowledge integration at the interface of ecology and health by publishing high quality research and review articles that address and profile new ideas, developments, and programs. The journal’s scope encompasses research that integrates concepts and theory from many fields of scholarship (including ecological, social and health sciences, and the humanities) and draws upon multiple types of knowledge, including those of relevance to practice and policy. Papers address integrated ecology and health challenges arising in public health, human and veterinary medicine, conservation and ecosystem management, rural and urban development and planning, and other fields that address the social-ecological context of health. The journal is a central platform for fulfilling the mission of the EcoHealth Alliance to strive for sustainable health of people, domestic animals, wildlife, and ecosystems by promoting discovery, understanding, and transdisciplinarity.
The journal invites substantial contributions in the following areas:
One Health and Conservation Medicine
o Integrated research on health of humans, wildlife, livestock and ecosystems
o Research and policy in ecology, public health, and agricultural sustainability
o Emerging infectious diseases affecting people, wildlife, domestic animals, and plants
o Research and practice linking human and animal health and/or social-ecological systems
o Anthropogenic environmental change and drivers of disease emergence in humans, wildlife, livestock and ecosystems
o Health of humans and animals in relation to terrestrial, freshwater, and marine ecosystems
Ecosystem Approaches to Health
o Systems thinking and social-ecological systems in relation to health
o Transdiiplinary approaches to health, ecosystems and society.
