hazards of disease transfer from marine mammals to land mammals: review and recent a 5-year study (1972-1977) of microbial agents isolated from both clinically normal and diseased marine mammals, it was shown that certain disease agents are widespread in a diversity of ocean populations and that some are also transmissible to a number of terrestrial mammal species. leptospira interrogans serovar pomona has been isolated repeatedly from 2 species of pinnipeds (zalophus californianus califonianus and callorhinus ursinus). some of the more important bacterial pathogens for lan ...1978738931
pleuritis and suppurative pneumonia associated with a hypermucoviscosity phenotype of klebsiella pneumoniae in california sea lions (zalophus californianus).the aim of this study is to document the isolation of a hypermucoviscosity (hmv) phenotype of klebsiella pneumoniae from 25 cases of suppurative pneumonia and pleuritis and two cases of abscesses in california sea lions (zalophus californianus) from the central california coast, representing the first report of this zoonotic pathogen from the marine environment and only the second report in non-humans. animals died 2h to 4 days after first being observed sick on beaches. clinical signs varied fr ...201019709820
hypervirulent klebsiella pneumoniae in california sea lions ( zalophus californianus): pathologic findings in natural infections.tissues of stranded california sea lions ( zalophus californianus) naturally infected with a hyperviruluent strain of klebsiella pneumoniae were examined by histopathology and immunohistochemistry against the k. pneumoniae k2 capsular antigen. in 7 of 8 animals, there was severe purulent bronchopneumonia, sometimes complicated by fibrinonecrotizing pleuritis with pyothorax. in affected areas of lung, large numbers of degenerate neutrophils and macrophages were admixed with rare large extracellul ...201728494709
