Serosurvey for selected viral pathogens among sympatric species of the African large predator guild in northern Botswana


Chaber, Anne-Lise; Cozzi, Gabriele; Broekhuis, Femke; Hartley, Robyn; McNutt, John W (2017). Serosurvey for selected viral pathogens among sympatric species of the African large predator guild in northern Botswana. Journal of Wildlife Diseases, 53(1):170-175.

Abstract

The recent increase in the creation of trans-boundary protected areas and wildlife corridors between them lend importance to information on pathogen prevalence and transmission among wildlife species that will become connected. One such initiative is the Kavango Zambezi Transfrontier Conservation Area (KAZA/TFCA) of which Botswana’s Okavango Delta constitute a major contribution in terms of wildlife and ecosystems. Between 2008 and 2011, we collected serum samples from 14 lions (Panthera leo), four leopards (P. pardus), 19 spotted hyenas (Crocuta crocuta), and six cheetahs (Acinonyx jubatus) in the Okavango. Samples were tested for antibodies against: canine distemper virus (CDV), feline panleukopenia virus, enteric coronavirus, feline calicivirus, feline herpesvirus (FHV-1), and feline immunodeficiency virus (FIV). Evidence of exposure to all of these pathogens was found to varying degrees in at least one of the species sampled. High seroprevalence (> 90%) was only found for FHV-1 and FIV in lions. Only hyenas (26%, 5/19) were seropositive against CDV. Apart from one case, all individuals displayed physical conditions consistent with normal health for a minimum of 12 months following sampling. Our results emphasize the need for a comprehensive multi-species approach to disease monitoring and the development of coordinated management strategies for sub-populations likely to be connected in trans-boundary initiatives.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
