Comparative study of 97 cultures of enterococci, including reference highly virulent strain Enterococcus faecalis ATCC 259212, 35 clinical isolates of E. faecium, 58 isolates of E. faecalis, and 3 probiotic strains of E. faecium: Linex (Lek company, Slovenia), SF68 (Bifiform, Denmark), and L3 (Avena, Russia). Thirteen of 93 cultures were isolated from patients treated with probiotic Linex, containing E. faecium (Linex) bacterium. Comparative analysis of cultures on the presence of 8 genes determining virulence (esp, asa1, efaA, cylA, cylM, gelE, sprE, and fsrB) was performed using polymerase chain reaction and testing with antibiotics. It was established that in some cases clinical cultures of enterococci used for analysis carried genes of pathogenicity and were not related to E. faecium (Linex) strain included in composition of the probiotic drug.

Aim: To evaluate the efficacy of the symbiotic Linex used in the combination therapy of liver cirrhosis (LC).
Subjects And Methods: Seventy-four patients with LC, including 44 who received additionally the symbiotic Linex and 30 who had conventional therapy, were examined. All the patients underwent clinical and biochemical blood tests, abdominal ultrasonography, fecal test for bacteria, gas chromatography-mass spectrometry of the blood composition of microbial markers, number connecting test, and quality-of-life assessment (SF-36).
