seroprevalence of selected disease agents from free-ranging black bears in florida.	sera obtained from 66 free-ranging florida black bears (ursus americanus floridanus) from three geographic areas of florida (usa) between november 1993 and august 1995 were tested for antibodies to 13 disease agents. antibody prevalences were 3 positive of 37 tested (8%) coxiella burnetti, 37 of 66 (56%) toxoplasma gondii, 3 of 61 (5%) bluetongue virus/epizootic hemorrhagic disease virus (btv/ehdv), 4 of 66 (6%) canine adenovirus-type 1, 5 of 66 (8%) canine distemper virus (cdv), 10 of 62 (16%) ...	1998	9706572
serological survey of selected canine viral pathogens and zoonoses in grizzly bears (ursus arctos horribilis) and black bears (ursus americanus) from alaska.	between 1988 and 1991, 644 serum samples were collected from 480 grizzly bears (ursus arctos horribilis) and 40 black bears (ursus americanus) from alaska, united states of america, and were tested for selected canine viral infections and zoonoses. antibody prevalence in grizzly bears was 0% for parvovirus, 8.3% (40/480) for distemper, 14% (68/480) for infectious hepatitis, 16.5% (79/480) for brucellosis, 19% (93/480) for tularaemia and 47% (225/478) for trichinellosis. in black bears, prevalenc ...	1998	9850547
antibodies to selected pathogens in free-ranging terrestrial carnivores and marine mammals in canada.	antibody titres to selected pathogens (canine adenovirus [cav-2], feline herpesvirus [fhv], phocine herpesvirus [phv-1], canine distemper virus, dolphin morbillivirus [dmv], phocine distemper virus [pdv], parainfluenza virus type 3 [pi3], rabies virus, dolphin rhabdovirus [drv], canine coronavirus, feline coronavirus, feline leukaemia virus, borrelia burgdorferi and toxoplasma gondii) were determined in whole blood or serum samples from selected free-ranging terrestrial carnivores and marine mam ...	2004	15338705
serosurvey for selected pathogens in free-ranging american black bears (ursus americanus) in maryland, usa.	american black bears (ursus americanus) in maryland, usa, live in forested areas in close proximity to humans and their domestic pets. from 1999 to 2011, we collected 84 serum samples from 63 black bears (18 males; 45 females) in five maryland counties and tested them for exposure to infectious, including zoonotic, pathogens. a large portion of the bears had antibody to canine distemper virus and toxoplasma gondii, many at high titers. prevalences of antibodies to zoonotic agents such as rabies ...	2014	25075540
demographic characteristics and infectious diseases of a population of american black bears in humboldt county, california.	american black bears (ursus americanus) are common, widely distributed, and broad-ranging omnivorous mammals in northern california forests. bears may be susceptible to pathogens infecting both domestic animals and humans. monitoring bear populations, particularly in changing ecosystems, is important to understanding ecological features that could affect bear population health and influence the likelihood that bears may cause adverse impacts on humans. in all, 321 bears were captured between may ...	2015	25700042
blindness in a wild american black bear cub (ursus americanus).	an approximately six-month-old wild american black bear (ursus americanus) was found wandering in saskatchewan and was presented to the veterinary medical centre of the western college of veterinary medicine for apparent blindness. clinical examination confirmed an inability to navigate a photopic maze, bilateral tapetal hyper-reflectivity, fundi devoid of retinal vessels, and small pale optic nerve papillae. single-flash electroretinography revealed a and b-wave amplitudes of approximately 40 a ...	2016	26302466
global mammal parasite database version 2.0.	illuminating the ecological and evolutionary dynamics of parasites is one of the most pressing issues facing modern science, and is critical for basic science, the global economy, and human health. extremely important to this effort are data on the disease-causing organisms of wild animal hosts (including viruses, bacteria, protozoa, helminths, arthropods, and fungi). here we present an updated version of the global mammal parasite database, a database of the parasites of wild ungulates (artioda ...	2017	28273333
