Evaluation of Macrolide-Lincosamide-Streptogramin B Antimicrobial Resistance at Swine Farms
… concern, the levels of macrolide-lincosamide-streptogramin B (MLSB) antimicrobial resistance at swine farms were quantified. A variation of fluorescence in situ hybridization (FISH) was developed to detect the methylation of a specific adenine residue (A2058 in Escherichia coli) in the 23S …

Molecular analysis of the extrachromosomal elements of Lactobacillus acidophilus strain 100-33
… resistance to macrolide, lincosamide, and streptogramin B-type antibiotics (MLS$\sp{\rm R}$) and tetracycline. Transformants with altered plasmid profiles had also become sensitive to the MLS antibiotics (McCarthy et al, 1988).

Antibiotics that Inhibit 30S or 50S Ribosomal Subunit Formation: Hygromycin B, Quinupristin-Dalfopristin and XRP 2868.
… translation and ribosomal subunit assembly. The streptogramin antibiotics quinupristin-dalfopristin and XRP 2868 (NXL 103) were examined for similar effects on these 2 cellular functions in antibiotic-resistant strains of <em>Haemophilus influenzae</em>, <em>Staphylococcus aureus</em>, and …

Mecanismos de resistencia a antibióticos macrólidos, lincosamidas y estreptograminas en streptococcus y enterococcus
… Characterization of macrolide, lincosamide and streptogramin (MLS) resistance mechanisms in Streptococcus and Enterococcus in La Rioja, from 1996 to 2001. Distribution of erythromcyin resistance phenotypes and involved mechanisms were studied for both genera, as well as temporary evolution and …

Molecular investigation of the influence of environmental factors and subinhibitory antibiotic concentrations on the biofilm formation in Staphylococcus epidermidis
… concentrations of tetracyline, the semisynthetic streptogramin quinupristin/dalfopristin and the streptogramin growth promoter virginiamycin were found to enhance the ica expression 8 to 11-fold, respectively, whereas penicillin, oxacillin, gentamicin, clindamycin, vancomycin, teicoplanin, …

Synthesis, Screening and Cocrystallization of Adenosine Based Inhibitors with Methyltransferases, ErmC' and KsgA
… to MLSB antibiotics (macrolides, lincosamides, streptogramin B). KsgA aids in ribosome assembly, binding inactive 30S until dimethylating A1518/A1519 of 16S rRNA. Like most methyltransferases, ErmC’ and KsgA use cofactor S-adenosylmethionine (SAM) as their methyl source, which binds adjacent to …

Studies on a 50S Ribosomal Precursor Particle as a Substrate for <em>erm </em>E Methyltransferase Enzyme in <em>Staphylococcus aureus </em>.
… curves showed that macrolide, lincosamide, and streptogramin B (MLS<sub>B</sub>) drugs bound to the precursor particle with similar affinity and inhibited the <em>erm</em>E methyltransferase activity. Competition experiments suggested that the enzyme can displace erythromycin from the 50S …

Nasopharyngeal colonization dynamics with Streptococcus pneumoniae and associated antimicrobial resistance in a South African birth cohort
… (52%, 172/329), macrolide-lincosamide-streptogramin (17%, 56/329), and tetracycline (12%, 38/329). The msrD, ermB, and mefA genes were only detected from pneumococcal reads. The predominant resistance genes detected from nonpneumococcal reads included blaOXA-60, blaOXA-22, and blaBRO-1. …

Impact of virginiamycin on the development of intestinal structure and functional capacity in growing pigs
Antibiotics have been used in animal feed to promote weight gain, improve feed efficiency, and control disease since the 1950s. Concerns about antibiotic resistance have increased since the widespread use of in-feed antibiotics began, but a clear connection between antibiotic use in animals and …
