Molecular typing and characterization of macrolide, lincosamide and streptogramin resistance in Staphylococcus epidermidis strains isolated in a Mexican hospital

Nomenclature for macrolide and macrolide-lincosamide-streptogramin B resistance determinants.

Characterisation and molecular cloning of the novel macrolide-streptogramin B resistance determinant from Staphylococcus epidermidis.

A total of 110 staphylococcal isolates from human skin were found to express a novel type of erythromycin resistance. The bacteria were resistant to 14-membered ring macrolides (MIC 32-128 mg/l) but were sensitive to 16-membered ring macrolides and lincosamides. Resistance to type B streptogramins was inducible by erythromycin. A similar phenotype, designated MS resistance, was previously descr...

Macrolide-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...

Prevalence of Macrolide-Lincosamide-Streptogramin B (MLSB) Resistance in S. aureus Isolated from Patients in Tehran, Iran

Background and Objectives: Staphylococcus aureus is an important cause of nosocomial and community-acquired infections in every region of the world. Clindamycin is one of the alternative agents used to treat S. aureus infections and accurate identification of clindamycin resistance is important to prevent therapeutic failure. Unfortunately, inducible clindamycin resistance is ...

Heterogeneity 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...
