Induction of ermsv by 16-membered-ring macrolide antibiotics.... Four types of responses which were correlated with the macrolide ring size were seen, as follows: group 1, both ermSV and ermC were induced by the 14-membered-ring macrolides erythromycin, lankamycin, and matromycin, as well as by the lincosamide celesticetin; group 2, neither ermSV nor ermC was induced by the 12-membered-ring macrolide methymycin or by the lincosamide lincomycin or the streptogramin type B antibiotic ostreogrycin B; group 3, ermSV was selectively induced over ermC by the 16-membered-ring macrolides carbomycin, chalcomycin, cirramycin, kitasamycin, maridomycin, and tylosin; and group 4, ermC was selectively induced over ermSV by the 14-membered-ring macrolide megalomicin....
A family of r-determinants in streptomyces spp. that specifies inducible resistance to macrolide, lincosamide, and streptogramin type b antibiotics.... hygroscopicus IFO 12995, which synthesize the macrolides tylosin and maridomycin, respectively, as well as in the lincosamide producer Streptomyces lincolnensis NRRL 2936 and the streptogramin type B producer Streptomyces diastaticus NRRL 2560....
