OCCURRENCE OF ENTEROCIN GENES AMONG ENTEROCOCCI STRAINS ISOLATED FROM HUMAN GASTROINTESTINAL TRACT
Journal Title: Мікробіологія і біотехнологія - Year 2016, Vol 0, Issue 2
Abstract
presence of enterocin genes among enterococci strains, isolated from gastrointestinal tract of elderly people. Methods. Polymerase chain reaction with primers specific to genes of enterocin А, В and Р and statistical data processing using cluster analysis. Results. Genes of enterocin А, В and Р were found in 21 from 58 (64%) enterococci strains, and in 13 strains were found two enterocin genes, and in 3 strains – genes of enterocin А, В and Р. The strains with narrow antagonistic spectrum harbored gene combinations А/В/Р, А/В, or one of the enterocin genes. The strains with wide antagonistic specrtum also harbored from 1 to 3 enterocin genes. No relation of antagonistic spectra from Enterococcus species was found. The presence of gene enterocin A, gene combinations А/В and А/В/Р was found only in E. faecium strains. Conclusions. Gene of enterocin P and gene combination А/Р were the most frequent among enterococci strains used. The spectrum of antagonistic activity does not depend on Enterococcus species and presence of enterocin genes А, В and Р.
