A. pleuropneumoniae. We tested this by electrotransformation of A. pleuropneumoniae 4074 with pHN61 as described above. In this transformant, the MICs of lincomycin and clindamycin increased from 16 to 128 mg/L and 4 to 64 mg/L respectively, whereas the MIC of erythromycin was unchanged (1 mg/L). The presence of pHN61 was verified by plasmid extraction and Southern blot hybridization. These res...

Background: Antibiotics called macrolide, lincosamide and streptogramin B (MLSB) are being used to treat staphylococci infections. Multiple pathways that impart resistance to MLSB antibiotics have been confirmed to cause clinical failure. The present work aimed to determine the frequency of constitutive and inducible clindamycin resistant among coagulase-negative staphylococci (CoNS) isolates o...

cin resistance and molecular epidemiologic trends of pediatric community-acquired methicillin-resistant Staphylococcus aureus in Dallas, Texas. Antimicrob Agents Chemother 2005; 49: 2283–8. 5. Hesenbein ME, Warner JE, Lambert KG et al. Detection of multiple macrolideand lincosamide-resistant strains of Streptococcus pyogenes from patients in the Boston area.

The transposon MTnSag1 from Streptococcus agalactiae carried an IS1-like transposase gene and the lnu(C) gene, which encoded a lincosamide nucleotidyltransferase. MTnSag1 could be mobilized by the conjugative transposon Tn916. An intermediate circular form of MTnSag1 and a putative origin of transfer at the 3' end of the lnu(C) gene were characterized.

The ErmB macrolide-lincosamide-streptogramin B (MLS) resistance determinant from Clostridium difficile 630 contains two copies of an erm(B) gene, separated by a 1.34-kb direct repeat also found in an Erm(B) determinant from Clostridium perfringens. In addition, both erm(B) genes are flanked by variants of the direct repeat sequence. This genetic arrangement is novel for an ErmB MLS resistance d...

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections increased from 2000 to 2003 in hospitalized pediatric patients in Houston. CA-MRSA was associated with greater illness than was infection with methicillin-susceptible strains. Children with CA-MRSA were younger and mostly African American. Of MRSA isolates, 4.5% had the inducible macrolide-lincosamide-streptog...

Methicillin-resistant Staphylococcus aureus clonal lineage ST398 and methicillin-susceptible lineage ST9 strains have their main reservoir in swine but can colonize and cause infections in humans. The phenicol/lincosamide/oxazolidinone/pleuromutilin/streptogramin A multidrug resistance gene cfr was detected in isolates of both clonal lineages, rendering a spread to humans with exposure to swine...

Sir, Recently in Australia, prescribing patterns for lincosamides have changed. Parenteral lincomycin use now exceeds parenteral clindamycin use in hospitals, including intensive care units. The reasons pertain to availability, cost and the recommendations of the national antibiotic guidelines. The Australian therapeutic guidelines present lincomycin and clindamycin as equivalent treatments for...

We assessed the in vitro activity of mirincamycin, a lincosamide antibiotic, against Plasmodium falciparum clinical isolates from Gabon. Growth was determined by HRP2 enzyme-linked immunosorbent assay using an adapted protocol with a prolonged incubation time (6 days) to account for antibiotic-induced delayed death. Mirincamycin's cis and trans isomers are more active (median 50% inhibitory con...

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 not detected by st...
