Abstract

Plasmid pIP501 was transferred by conjugation from Lactococcus lactis to Lactobacillus delbrückii subsp. bulgaricus and Lactobacillus helveticus. Only Lb. delbrückii subsp. bulgaricus transconjugants could act as a donor in crosses with Lc. lactis. No Lactobacillus transconjugants were detected after inter- or intra-species Lactobacillus crosses. Plasmid pIP501 has undergone no detectable deletion or rearrangement during transfer from Lc. lactis to Lactobacillus strains.
