We report a case of a surgical site infection caused by clindamycin-susceptible, erythromycin-resistant methicillin-resistant Staphylococcus aureus (MRSA) that did not respond to treatment with clindamycin. The MRSA isolate obtained after treatment was resistant to clindamycin but was found to be identical by pulsed-field gel electrophoresis to the clindamycin-susceptible isolate obtained befor...

Resistance to lincomycin and clindamycin in the clinical isolate Enterococcus faecium HM1025 is due to a ribosomal methylase encoded by an ermAM-like gene and the plasmid-mediated inactivation of these antibiotics. We have cloned and determined the nucleotide sequence of the gene responsible for the inactivation of lincosamides, linB. This gene encodes a 267-amino-acid lincosamide nucleotidyltr...

The effects of seven antibiotics (streptomycin, amikacin, polymyxin B, lincomycin, clindamycin, tetracycline and oxytetracycline) were compared with those of magnesium, tubocurarine and lignocaine in the frog sciatic nerve--sartorius muscle preparation, using intracellular recording techniques. All compounds except tubocurarine decreased end-plate potential quantal content. The prejunctional ef...

Sir, Spectinomycin resistance in staphylococci is mostly mediated by spectinomycin 9-O-adenyltransferase encoded by the spc gene. This gene is located together with the macrolide– lincosamide–streptogramin B resistance gene erm(A) on transposon Tn554. The analysis of methicillin-resistant Staphylococcus aureus (MRSA) CC398 from cases of bovine mastitis showed that all spectinomycin-resistant is...

The aim of this study was to determine the presence methicillin resistant staphylococci (MRS) in retail raw chicken meat samples sold Hatay. antimicrobial susceptibility isolates tested for 13 different antimicrobials by disc diffusion method and investigated resistance genes encoding (mecA), tetracycline (tetM, tetK), penicillin (blaZ), macrolide (ermA, ermC), lincosamide (lnuA) aminoglycoside...

OBJECTIVE Our objective was to assess the ability of real-time PCR to predict in vitro resistance in isolates of group B streptococcus (GBS). METHODS The first real-time PCR assays for the genes known to confer resistance to erythromycin and clindamycin in GBS were developed. Three hundred and forty clinical GBS isolates were assessed with these assays and compared with conventional disk diff...
