[Parasitocenotic relationships in the marita micropopulations of Opisthorchis and opportunistic microorganisms (an in vitro model)].

The purpose of this investigation was to determine the relation of exometabolites of Opisthorchis maritas and the bacteria Klebsiella pneumoniae and Staphylococcus aureus, by studying some physiological functions of mature Opisthorchis and the properties of bacteria in the artificial media during co-cultivation. Its modified procedure was used to examine tile hature of relationships in the micro- population of the parasite and opportunistic bacteria. The Opistorchis felineus maritas obtained from the liver of an infested animal were the object of helminthological examinations. Co-cultivation of the bacteria Klebsiella pneumoniae and Staphylococcus aureus with Opistorchis felineus maritas showed that the latter exerted some inhibitory effects on the growth and reproduction of bacteria; moreover, there were no changes in their biochemical processes, virulence factors; and antibiotic susceptibility.
