Inducible macrolides-lincosamides-streptogramin B resistance in Bacteroides species.
The first evidence is presented for the presence of inducible macrolides-lincosamides-streptogramin B resistance in Bacteroides species. Different macrolides induced clindamycin resistance in Bacteroides vulgatus RYC18F6, an erythromycin-resistant and clindamycin-susceptible strain. A study of 144 Bacteroides isolates indicated that erythromycin resistance was linked to diminished clindamycin s...
متن کاملPneumococcal resistance to macrolides, lincosamides, ketolides, and streptogramin B agents: molecular mechanisms and resistance phenotypes.
The macrolides, lincosamides, ketolides, and streptogramin B agents (the MLKS(B) antimicrobial agents) have related chemical structures and share similar molecular targets on the 50S ribosomal subunit of Streptococcus pneumoniae. Mutations in rRNA or ribosomal proteins generate a variety of resistance phenotypes. The M phenotype of S. pneumoniae, which predominates in North America, affords low...
متن کاملEpidemiology of drug resistance: the case of Staphylococcus aureus and coagulase-negative staphylococci infections.
OBJECTIVE To study the activity of several antibiotics against Staphylococcus spp. MATERIAL AND METHODS The study included 1209 strains of Staphylococcus spp. from two institutions; Instituto Nacional de Pediatría (National Institute of Pediatrics) and Hospital Infantil de México Federico Gómez (Mexico City Children's Hospital). Minimum Inhibitory Concentrations of all antibiotics were determ...
متن کاملComparison of culture media for detecting methicillin resistance in Staphylococcus aureus and coagulase negative staphylococci.
The detection of methicillin resistance was examined in 51 strains of Staphylococcus aureus and 135 strains of coagulase negative staphylococci using Isosensitest, Diagnostic Sensitivity Test (DST), Mueller-Hinton (MH), Columbia, and Sensitest agars. MH agar with 5% added sodium chloride incubated at 35 degrees C was the most effective in detecting resistance in S aureus, and Columbia agar with...
متن کاملMacrolide-lincosamide-streptogramin resistance phenotypes and genotypes of coagulase-positive Staphylococcus aureus and coagulase-negative staphylococcal isolates from bovine mastitis
BACKGROUND There are limited data available on macrolide-lincosamide-streptogramin (MLS) resistance of Staphylococcus aureus (S. aureus) and coagulase-negative staphylococci (CoNS) from bovine milk in China. To address this knowledge gap, MLS resistance was determined in 121 S. aureus and 97 CoNS isolates. Minimum inhibitory concentrations (MICs) of MLS antibiotics were determined by an agar di...
