Popis: The study of the circulating strains of enteropathogenic Escherichia coli (EPEC), shigellae and salmonellae for the presence of F-factor (the conjunction factor) was carried out. The study revealed that 85% of Shigella flexneri strains 2a had conjugative (F)-factor. The proportion of such strains was 63% among EPEC of different serovars and 15% among Salmonella enteritidis. As 63% EPEC strains had hemolytic activity and were found to carry F-conjugative plasmid it should be taken into consideration in the identification of microorganisms. The presence of conjugation plasmids is an important epidemiological marker.
