Mechanism Description The cfr gene encodes the Cfr methyltransferase that methylates a single adenine in the peptidyl transferase region of bacterial ribosomes.Expression of the genes was induced in Escherichia coli, and MICs for selected antibiotics indicate that the cfr-like genes confer resistance to PhLOPSa (phenicol, lincosamide, oxazolidinone, pleuromutilin, and streptogramin A) antibiotics in the same way as the cfr gene.The Cfr-like proteins ClbA, ClbC, and ClbB confer a resistance pattern similar to that of the Cfr methyltransferase.

Mechanism Description Abundant amplificationproducts of slightly less than 400 bp were generated from DNAisolated from the 17 MLSb-resistant strains, whereas no am-plification products were generated with the DNA isolatedfrom the three susceptible strains. The DNA sequences of the amplification products showed 95% identity to the erm(X) gene isolated from a C. xerosis strain,erm(X)cx or ermCX. Thus, MLSb resistance in C. jeikeiumis associated with the presence of an allele, erm(X)cj, of the class Xermgenes. The first 215 amino acids of the predicted polypeptides for strains CJ12 and CJ21 are 93.5 and 98.6% identical to Erm(X)cx, the Erm protein from C. xerosi. The major difference between the two Erm(X)cj polypeptides and the Erm(X)cx polypeptide is a frame shift within codon 216. This results in the Erm(X)cj polypeptides being 31 amino acids longer than Erm(X)cx.

Mechanism Description Using the Ery- strain AR1807 as a recipient for plasmid-directed integrative recombination, the chromosomal ermR gene (encoding 23S rRNA methyltransferase) was disrupted, ermR-disrupted strains AR1848 and AR1849 were highly sensitive to erythromycin and the other macrolide antibiotics. Phenotypic characterizations demonstrated that ermR is the sole determinant of macrolide antibiotic resistance in A. erythreum. AR18, AR1807, and AR1850 (Ery- Ermr) were resistant to clindamycin, erythromycin, spiramycin, and tylosin (some sensitivity totylosin was observed at high concentrations).

Mechanism Description ABC systems constitute one of the largest families of proteins, with most of them being involved in import and export, often called ABC transporters.Several of these class 2 ABC systems have been involved in MLS resistance, such as Msr-, Vga-, or Lsa-like proteins.The observed profile of cross-resistance to lincosamides, streptogramins A, and pleuromutilins conferred by Eat(A)v was similar to those conferred by other Lsa-like proteins.

Resistant Disease Clostridium difficile infection [ICD-11: 1A04.0]
Experimental Note Discovered Using In-vivo Testing Model
Mechanism Description The cellular methylation in C. difficile has been proposed to induce resistance to macrolides (erythromycin, ERY), lincosamide (clindamycin) and streptogramin B antibiotic family. These drugs target at a bacterial 50S ribosomal subunit, causing the inhibition of peptide chain growth by blocking the movement of ribosome. ERY ribosomal methylase B (ErmB) is responsible for ribosomal methylation at the specific site of 23S rRNA, resulting in the prevention of antibiotic binding.

Mechanism Description Expression of this novel gene, named lsa(C), in S. agalactiae BM132 after cloning led to an increase in MICs of lincomycin (0.06 to 4 ug/ml), clindamycin (0.03 to 2 ug/ml), dalfopristin (2 to >32 ug/ml), and tiamulin (0.12 to 32 ug/ml), whereas no change in MICs of erythromycin (0.06 ug/ml), azithromycin (0.03 ug/ml), spiramycin (0.25 ug/ml), telithromycin (0.03 ug/ml), and quinupristin (8 ug/ml) was observed. The phenotype was renamed the LS(A)P phenotype on the basis of cross-resistance to lincosamides, streptogramins A, and pleuromutilins.

Mechanism Description The erm genes are a diverse collection of methylases that add one or two methyl groups to the adenine at position 2058 (Escherichia coli numbering) of the 23S rRNA; this modification impairs the binding of macrolides to ribosomes, and thus reduces the inhibitory activity of these agents.

Mechanism Description Clindamycin resistance in Bacteroides spp. is usually macrolide-lincosamide-streptogramin B (MLS) resistance conferred by erm genes which are similar to those seen in gram-positive, facultative anaerobes. Of 13 clinical isolates of the Bacteroides group, all were resistant to tetracycline (>10,ug/ml).

Mechanism Description Expression of this novel gene, named lsa(C), in S. agalactiae BM132 after cloning led to an increase in MICs of lincomycin (0.06 to 4 ug/ml), clindamycin (0.03 to 2 ug/ml), dalfopristin (2 to >32 ug/ml), and tiamulin (0.12 to 32 ug/ml), whereas no change in MICs of erythromycin (0.06 ug/ml), azithromycin (0.03 ug/ml), spiramycin (0.25 ug/ml), telithromycin (0.03 ug/ml), and quinupristin (8 ug/ml) was observed. The phenotype was renamed the LS(A)P phenotype on the basis of cross-resistance to lincosamides, streptogramins A, and pleuromutilins.
