Abstract
The relevance of the ecological problem of the mass death of the Baikal seal (Pusa sibirica Gm.) forces researchers to establish causes of this phenomenon. The article presents the results of microbiological studies of swabs isolated from the nasal, oral cavities and rectum. The taxonomic characteristics of microorganisms and their virulence were studied. 14 Baikal seals found in the nerpinaria of Listvyanka were tudied. It was established that in the seal there are the following microorganisms: Clostridium perfringens, Escherichia coli, Enterococcus faecalis, Staphylococcus warneri, Pseudomona aeruginosa, Staphylococcus epidermidis, Staphylococcus aureus, Proteus hauseri, Proteus vulgaris bellisella, Proteus migarisella, rabitemorganii, Psychrobactersanguinis, Enterobacter cloacae. When studying the virulence of microorganisms, it was found that 58% of the strains do not cause the death of laboratory animals, they are mainly the representatives of opportunistic microflora. 42% of the strain were pathogenic, of which two strains of Plesi omonas shigelloides and 42 strains of Clostridium perfringens were identified.
