Sci Rep. Moreover, 8. Performance standards for antimicrobial susceptibility testing: Twentieth informational supplement. The tetM gene was absent in all the tetracycline-susceptible isolates. Macrolide therapy is a cornerstone of the treatment of infections caused by macrolide-susceptible rapidly growing mycobacteria RGM. Binding site of macrolide antibiotics on the ribosome: new resistance mutation identifies a specific interaction of ketolides with rRNA. Molecular basis of intrinsic macrolide resistance in clinical isolates of Mycobacterium fortuitum. However, the isolates were highly sensitive to the following antibiotics: teicoplanin 0 resistant strainslinezolid 0 resistant strainsand vancomycin 0 resistant strainssimilar to other reports [ 16 ]. The presence of a wide range of erythromycin resistance genes in Enterococcus species has been reported elsewhere [ 20 ]. Iran J Microbiol.

    This ribosomal region, in the 23S component region of the 50S ribosome, termed "domain V", where V is the Roman numerial indicating the number 5. The protein encoded by the tetM gene blocks the binding of tetracycline to the ribosome by combining with the 50S ribosomal subunit, causing a conformational change in the ribosome that subsequently produces drug resistance. The resistance rate of the clinical isolates of enterococci species to various antimicrobial agents.

    Antimicrobial susceptibility testing was performed by using the disc diffusion method according to the standards and interpretive criteria described by the Clinical and Laboratory Standards Institute CLSI [ 9 ].

    Main text Methods Bacterial strains and identification A total of 73 clinical isolates of enterococci were collected from the Second Affiliated Hospital of Baotou Medical College in Baotou, China, between December and September Phenotypic detection of macrolide resistance in some RGM is complicated by the fact that some Erms are inducible and difficult to detect unless the bacterium is incubated with the test macrolide for up to 14 days.

    Of the 31 erythromycin-resistant isolates of E. However, many rapidly growing mycobacteria are macrolide resistant due to bacterial genes that encode proteins that methylate ribosomal DNA in a critical region of the large subunit 50S ribosome. This value is close to that obtained in our present study Domain V is the region in which macrolides bind to the ribosome, and a single methylation or mutation of critical bases can result in a conformational change that results in macrolide resistance.

    All strains were sensitive to teicoplanin, vancomycin and linezolid.
