Conjugal Transfer of Broad-Host-Range Plasmid pAMbeta1 into Enteric Species of Lactic Acid Bacteria.
The broad-host-range plasmid pAMbeta1, which codes for erythromycin and lincomycin resistance, was transferred by conjugation into Lactobacillus acidophilus, Lactobacillus reuteri, and Lactobacillus salivarius. A novel 17-megadalton plasmid molecule was detected in the transconjugants, confirming the introduction of pAMbeta1 into each species.
