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.

Discharge of sewage into the ocean is still a common method of disposal worldwide. Both treated and untreated sewage may contain significant concentrations of waterborne pathogens, such as Giardia, Cryptosporidium, poliovirus and Salmonella. Limited studies exist on the survival of poliovirus and Salmonella in marine waters; however, almost no information exists on the survival of protozoan parasites in marine waters. This study examined the survival of Giardia muris cysts, Cryptosporidium parvum oocysts, poliovirus-1 and Salmonella typhimurium in marine waters. The survival of the microorganisms varied according to the presence of light, salinity and water quality (as determined by quantity of enterococci). All microorganisms survived longer in the dark than in sunlight, the order of survival in sunlight being: Cryptosporidium > poliovirus > Giardia > Salmonella.
