The streptococcal plasmid pAM beta 1 (erythromycin resistance) was transferred via conjugation from Streptococcus faecalis to Lactobacillus plantarum and was transferred among L. plantarum strains. Streptococcus sanguis Challis was transformed with pAM beta 1 isolated from these transconjugants, and transformants harboring intact pAM beta 1 could conjugate the plasmid back to L. plantarum.
链球菌质粒pAMβ1(红霉素抗性)通过接合作用从粪链球菌转移至植物乳杆菌,并在植物乳杆菌菌株间转移。用从这些接合子中分离得到的pAMβ1转化血链球菌Challis,携带完整pAMβ1的转化子可将该质粒再接合回植物乳杆菌。
