Fig. 2From: Horizontal transfer of vanA between probiotic Enterococcus faecium and Enterococcus faecalis in fermented soybean meal and in digestive tract of growing pigsViable count of Efm4, Efs2 and transconjugants in feceal samples of growing pigs. (a): The growth kinetics of donor strain Efm4 in Efm4 group, Efm4+ Efs2 group and FSBM group; (b): The growth kinetics of receiver strain Efs2 in Efs2 group, Efm4+ Efs2 group and FSBM group; (c): The growth kinetics of transconjugants in Efm4+ Efs2 group and FSBM group. In both Efm4+ Efs2 group and FSBM group, the transconjugants were only detected in one pig out of six. Results from fecal samples obtained at 24 h before the experiment are plotted as day zero. FSBM, fermented soybean meal; Efm4, vanA positive strain Enterococcus faecium Efm4; Efs2, chloramphenicol-resistant strain Enterococcus faecalis Efs2Back to article page
