| sequence analyses of a broad host-range plasmid containing ermt from a tylosin-resistant lactobacillus sp. isolated from swine feces. | anaerobic bacteria resistant to the macrolide antibiotics tylosin and erythromycin were isolated from the feces of swine. one of the strains, 121b, was initially identified by 16s rdna sequence analysis as an unknown lactobacillus sp. the strain was found to contain at least two plasmids, one of which was capable of replicating and providing erythromycin and tylosin resistance to bacillus subtilis, streptococcus gordonii, and escherichia coli. dna sequence analyses of the 4,232-bp plasmid, p121b ... | 2001 | 11375658 |
| molecular characterization of a plasmid-borne (pgt633) erythromycin resistance determinant (ermgt) from lactobacillus reuteri 100-63. | lactobacillus reuteri 100-63 contains a 9.8 kb plasmid (pgt633) encoding resistance to the macrolide-lincosamide-streptogramin (mls) type b antibiotics. the restriction endonucleases acci, bamhi, bcli, ecori, ecorv, hhai, hindii, hpai, kpni, sali, and sspi were employed to establish a physical map of pgt633. next, genetic transfer experiments were conducted to establish the host range of pgt633. the results revealed that pgt633 replicated autonomously and encoded constitutive resistance to eryth ... | 1994 | 8171126 |
