| Popis: | The article is devoted to the study of biological activity, including pathogenicity factors, of marine bacteria isolated from water in areas with different anthropogenic load, both coastal zones with high levels of different pollutants and pure zones with no human impact. To maintain the experimental integrity, we excluded Enterobacteriaceae from the obtained collection of marine microorganisms. Then we worked with the rest of the isolates for detection of their hydrolytic activity toward organic substrates, antibiotic resistance and such pathogenicity factors as: cytotoxicity, hemolytic activity, plasma coagulase and hyaluronidase activities. Comparative studies of hydrolytic activity in microorganisms isolated from sea water with different anthropogenic load have not revealed any differences in these indicators. However, the strains isolated from water areas with great impact of industrial, domestic and river drains, were highly antibiotic-resistant, highly adhesive and cytotoxic compared to the strains isolated from pure sea water. It is assumed that pollution of marine environment results in manifestation of aggressive properties of microorganisms, as a response to impact of stress factors that is both of general biological, ecological and epidemiological significance. |
