In vitro evaluation of the antibacterial activities of radezolid and linezolid for Streptococcus agalactiae.
This study aims to evaluate the antimicrobial activities of linezolid and radezolid against Streptococcus agalactiae in vitro and compared for genetic resistance factors.. Nonduplicate S. agalactiae clinical isolates (n = 136) were collected and the minimal inhibitory concentrations of antimicrobials were determined by agar dilution methodology. The linezolid-resistant mechanism in the clinical linezolid-non-susceptible S. agalactiae isolates and that induced by linezolid pressure in vitro were analyzed by PCR and sequence alignment. Antimicrobial activities and resistance mechanism distinctions between linezolid and radezolid were further investigated in the clinical linezolid-non-susceptible S. agalactiae isolates and that induced by linezolid pressure in vitro.. Our data indicated that 17 (13%) of the 136 clinical S. agalactiae isolates were not susceptible to linezolid. For individual S. agalactiae isolates, including linezolid-nonsusceptible isolates with 23S rRNA V domain mutations, radezolid MIC. Radezolid exhibits stronger potency against S. agalactiae than linezolid and there is a concerning presence of linezolid-nonsusceptible S. agalactiae in clinical samples.
