Analysis of the mechanisms of quinolone resistance in clinical isolates of Citrobacter freundii.

The Journal of antimicrobial chemotherapy - 1 Dec 1999

Navia M M, Ruiz J, Ribera A, de Anta M T, Vila J

Abstract excerpt

The presence of gyrA, gyrB and/or parC mutations, quinolone uptake, outer membrane protein profiles and epidemiological relationship were studied in 12 clinical isolates of Citrobacter freundii. No alterations were observed in the gyrB gene of any of the strains, or gyrA or parC of the four quinolone-susceptible strains (nalidixic acid MIC of 2-4 mg/L, and a ciprofloxacin MIC of 0.006-0.06 mg/L). The...
