对食品中48株屎肠球菌和47株粪肠球菌的毒力因子发生率及药敏情况进行了调查。没有菌株对所有抗生素具有耐药性，并且对于某些菌株，观察到多重耐药性。在粪肠球菌菌株中，10.4% 的一种或多种毒力决定子呈阳性，而粪肠球菌菌株的这一比例为 78.7%。表现出毒力特征的菌株并不一定对所有特征都呈阳性；因此，毒力因子的发生率可被认为是菌株特异性的。
The incidence of virulence factors among 48 Enterococcus faecium and 47 Enterococcus faecalis strains from foods and their antibiotic susceptibility were investigated. No strain was resistant to all antibiotics, and for some strains, multiple resistances were observed. Of E. faecium strains, 10.4% were positive for one or more virulence determinants, compared to 78.7% of E. faecalis strains. Strains exhibiting virulence traits were not necessarily positive for all traits; thus, the incidence of virulence factors may be considered to be strain specific.
