Resistance to Lincomycin. Resistance to lincomycin is developed slowly, and is usually caused by modification of 23S ribosomal RNA, which leads to co-resistance to macroHde, lincosaminide, and streptogramin B antibiotics (25). Inactivation of lincomycin by clinical isolates of strains of Staphjlococcus aureus and Staphjlococcus haemoljticus, though retention of sensitivity to macroHdes (see Antibiotics, macrolides) and streptogramins (see Antibiotics, peptides), has been found to be the consequence of the conversion of the antibiotic into its 3-(5 -adenylate) (26). [Pg.87]

Hydrolysis of macrolides by products of the ere genes detected in enterobacteria is only of scientific interest, while esterases VGB-A and VGB-B encoded by the vgb type genes mediate clinically relevant resistance in staphylococci to the B compound (quinupristin) of the streptogramin combination quinu-pristin-dalfopristin. [Pg.103]

Resistance to the A compound of streptogramins is mediated by products of the vat genes (virginiamycin acetyliransferase), of which at least five molecular classes are known (vatA-E). These genes are located on plasmids of Enterococcus faecium and frequently in combination with a gene encoding a streptogramin hydrolase (vga/vgb) in staphylococci. [Pg.104]

Resistance to streptogramin type B antibiotics can be mediated in staphylococci and enterococci by plasmids carrying a vgb gene [2]. The Vgb enzyme is a lyase that linearizes the cyclic hexadepsipeptide by cleavage of the ester bond via an elimination reaction. [Pg.771]

Macrolide, lincosamide and streptogramin B resistance (MLSb phenotype) can be linked to specific nucleotide changes within the 23 S rRNA of the large ribosomal subunit, mainly at position A2058 or neighbouring bases (E. coli numbering). This is the... [Pg.773]

A gene designated msrA has been identified in Staph, aureus which confers resistance to macrolides and streptogramins but not to lincosamides. Its function is unknown but the DNA sequence is homologous to genes coding for known efflux proteins. [Pg.191]
