Nucleotide sequence of the constitutive macrolide-lincosamide-streptogramin B resistance plasmid pNE131 from Staphylococcus epidermidis and homologies with Staphylococcus aureus plasmids pE194 and pSN2.
The complete nucleotide sequence of the Staphylococcus epidermidis plasmid pNE131 is presented. The plasmid is 2,355 base pairs long and contains two major open reading frames. A comparison of the pNE131 DNA sequence with the published DNA sequences of five Staphylococcus aureus plasmids revealed strong regional homologies with two of them, pE194 and pSN2. The region of pNE131 containing the re...
متن کاملMacrolide-lincosamide-streptogramin resistance patterns in Clostridium perfringens from animals.
Different patterns of resistance against commonly used macrolide, lincosamide, and streptogramin antibiotics were found in Clostridium perfringens of animal origin. The patterns were designated as (i) macrolide-lincosamide-streptogramin group B generalized resistance, (ii) macrolide-lincosamide generalized resistance, (iii) macrolide-lincosamide inducible resistance, and (iv) macrolide-lincosam...
متن کاملHeterogeneity of macrolide-lincosamide-streptogramin B resistance phenotypes in enterococci.
We determined the macrolide resistance phenotypes of 241 clinical isolates of erythromycin-resistant enterococci (MICs, > or = 1 microg/ml), including 147 Enterococcus faecalis strains and 94 Enterococcus faecium strains, collected from a hospital in Seoul, Korea, between 1999 and 2000. By the erythromycin (40 micro g)-josamycin (100 microg) double-disk test, 93 strains were assigned to the con...
متن کاملNovel locus required for expression of high-level macrolide-lincosamide-streptogramin B resistance in Staphylococcus aureus.
The yycF1(Ts) mutation in Staphylococcus aureus conferred hypersensitivity to macrolide-lincosamide-streptogramin B (MLS(B)) antibiotics on strains either containing or lacking ermB. The overexpression of the S. aureus Ssa protein restored the yycF1 mutant to wild-type levels of susceptibility. Inactivation of ssa in an unmutagenized strain dramatically reduced ermB-based resistance. Conditiona...
