The analysis of cases of detection of bacteria of the genus Aeromonas in clinical material from various
loci of patients of medical organizations was carried out. Their species diversity, isolation in
monoculture and associations, resistance to antibiotics and spring-autumn rises indicate the etiological
significance of these microorganisms in the infectious process. To improve the biological safety of aquatic
biotopes, it is important to study their microbiocenosis, in particular, the circulation of bacteria of the
genus Aeromonas, in order to obtain information on pathogenic properties, antibiotic resistance, and
seasonal fluctuations. To prevent the spread of Aeromonas infections, it is necessary to carry out
sanitary and bacteriological studies of water bodies, environmental objects and food products.
