ABSTRACT
The data on the cytopathogenic activity of campylobacteria isolated from different sources are presented. 84.7 % of the isolated campylobacteria have been shown to possess cytopathogenicity with respect to Hep-2 cell cultures. The greatest number of highly cytopathogenic strains (52.6 %) has been registered among clinical isolates of campylobacteria. At the same time 44.1 % of highly cytopathogenic strains have been isolated from chickens, which is indicative of the potential danger of poultry as the source of Campylobacter infection. In the course of the epidemiological surveillance of campylobacteriosis the determination of cytopathogenically active Campylobacter strains is necessary.

Composition of fatty acids of total lipids in home strains of campylobacteria has been studied. Lipids of all the strains of C. jejuni and C. coli mainly consist of saturated fatty acids (from 75.7 to 78.7%) with predominance of tetradecanoic and hexadecanoic fatty acids. The level of unsaturated fatty acids is considerably lower (from 21.0 to 22.5%); These acids are mainly presented by hexadecene acid. Qualitative composition of fatty acids of total lipids in C. jejuni and C. coli does not permit using it for differentiation within these species.

Clinical course and epidemiological features of campylobacteriosis in Ukraine are described. The disease accounts for 11.2% of the total number of acute enteric infectious cases. Ratio of bacterial contamination of hens and their role in spread of campylobacteriosis have been established. Possible ways of transfer of the infection are discussed.

Various types of echinococcosis foci were detected in the Ukrainian Soviet Socialist Republic: steppe zone foci with sheep pattern circulation dominating, where invasion is transmitted according to scheme: sheep--dogs attached to flocks; forest lowland and forest-steppe zones with pig pattern of echinococcosis circulating, where invasion is transmitted according to scheme: pigs--dogs. In steppe zone foci cases of echinococcosis in humans are regularly recorded and a large stratum of seropositive subjects was revealed by the indirect hemagglutination and latex agglutination tests. In second type foci only single cases of human echinococcosis were observed and low seropositive stratum was detected. Complex of antiechinococcosis measures conforming to different foci types was developed.
