Novel Bartonella infection in northern and southern sea otters (Enhydra lutris kenyoni and Enhydra lutris nereis).
Since 2002, vegetative valvular endocarditis (VVE), septicemia and meningoencephalitis have contributed to an Unusual Mortality Event (UME) of northern sea otters in southcentral Alaska. Streptococcal organisms were commonly isolated from vegetative lesions and organs from these sea otters. Bartonella infection has also been associated with bacteremia and VVE in terrestrial mammals, but little ...
متن کاملPatterns of mortality in southern sea otters (Enhydra lutris nereis) from 1998-2001.
Detailed postmortem examination of southern sea otters (Enhydra lutris nereis) found along the California (USA) coast has provided an exceptional opportunity to understand factors influencing survival in this threatened marine mammal species. In order to evaluate recent trends in causes of mortality, the demographic and geographic distribution of causes of death in freshly deceased beachcast se...
متن کاملCharacterization of the Temporomandibular Joint of Southern Sea Otters (Enhydra lutris nereis)
The structure-function relationship of the temporomandibular joint (TMJ) of southern sea otter has largely not been described. This study aims to describe the histological, biochemical, and biomechanical features of the TMJ disk in the southern sea otter. The TMJ disks from fresh cadaver heads of southern sea otter adult males (n = 8) and females (n = 8) acquired from strandings were examined. ...
متن کاملBiological and molecular characterizations of Toxoplasma gondii strains obtained from southern sea otters (Enhydra lutris nereis).
Toxoplasma gondii was isolated from brain or heart tissue from 15 southern sea otters (Enhydra lutris nereis) in cell cultures. These strains were used to infect mice that developed antibodies to T. gondii as detected in the modified direct agglutination test and had T. gondii tissue cysts in their brains at necropsy. Mouse brains containing tissue cysts from 4 of the strains were fed to 4 cats...
متن کاملCharacterization of beta-hemolytic streptococci isolated from southern sea otters (Enhydra lutris nereis) stranded along the California coast.
The goal of this study was to characterize the beta-hemolytic streptococci cultured from southern sea otters (Enhydra lutris nereis) stranded off the coast of California (USA) and to verify identifications made using the Lancefield system. Lancefield serotyping and biochemical analysis alone was inadequate for isolate characterization. Final identification was based on sequence analysis of a po...
