In fall 1991, a radio-collared black bear (Ursus americanus) in northern La
brador (Canada) died from valvular endocarditis caused by coagulase-positiv
e Staphylococcus aureus, with widespread dissemination of the infection to
other organs shortly before death. Apparently, this is the first reported c
ase of bacterial valvular endocarditis in a wild black bear.
