Title: Serologic Survey of Selected Viral Pathogens in Free-Ranging Brown Bears (Ursus arctos) from Slovakia
Biography: Eva Bártová
The aim of study was to test sera of bears from Slovakia for antibodies to 10 viral pathogens. Similar study, in free-ranging European brown bears (Ursus arctos), has been performed only in Croatia and Italy. The sera were collected from 24 free-ranging brown bears killed for public safety reasons in six various regions of Slovakia between years 2011 and 2015. We tested sera by Indirect fluorescence antibody test for antibodies to canine distemper virus (CDV), canine coronavirus (CCV), canine parvovirus type 2 (CPV-2), canine adenovirus (CAV), canine parainfluenza virus type 2 (CPIV-2) and canine herpesvirus type 1 (CHV-1). We used Enzyme-linked immunosorbent assay for detection of antibodies to hepatitis E virus (HEV), bluetongue virus (BTV), West-Nile virus (WNV) and Aujeszky’s disease virus (ADV). We detected antibodies to CDV in seven animals (29 %), antibodies to CHV in three animals (13 %), antibodies to CPV-2 and CPIV-2 in two animals (8 %), while antibodies to CCV, WNV and ADV in one animal (4 %). To our knowledge, this is the first report of CCV and ADV exposure in free-ranging brown bears.
