Antibiotic-resistant opportunistic bacteria in the coastal zone of Lake Baikal

Аннотация

This work presents the diversity and antibiotic sensitivity of opportunistic bacteria isolated from plankton and biofilms in the coastal zone of Lake Baikal. Using modern identification methods (molecular genetic and mass spectrometry analyses), we determined that bacteria identified in biotopes belong to the genera Escherichia, Citrobacter, Hafnia, Enterobacter, Shigella, Yersinia, Serratia, Pseudomonas, Acinetobacter, Bacillus, Enterococcus, Staphylococcus, which are mostly the cause of community-acquired and nosocomial infections. The bulk of isolates showed polyresistance to wide-spectrum antibiotics (-lactams and sulphanilamides).
