The effects of increasing levels of quinolone resistance on in-vitro activity of four quinolones.
A panel of 266 clinically isolated Gram-positive cocci and Gram-negative bacilli with varying levels of resistance to ciprofloxacin were analysed for susceptibility to Du-6859a, ciprofloxacin, ofloxacin, temafloxacin and nalidixic acid. Staphylococci were divided into ciprofloxacin-susceptible, moderately resistant and highly resistant subgroups. Du-6859a was the most potent quinolone against a...
متن کاملIn vitro development of resistance to five quinolones and amoxicillin-clavulanate in Streptococcus pneumoniae.
The ability of 50 sequential subcultures in subinhibitory concentrations of ciprofloxacin, levofloxacin, grepafloxacin, sparfloxacin, trovafloxacin, and amoxicillin-clavulanate to select for resistance was studied for six penicillin-susceptible and four penicillin-intermediate pneumococci. Subculturing in ciprofloxacin, grepafloxacin, levofloxacin, and sparfloxacin led to selection of mutants r...

15 صفحه اولMolecular epidemiology of quinolone resistance and comparative in vitro activities of new quinolones against European Staphylococcus aureus isolates.
UNLABELLED New fluoroquinolones (FQ) may possibly be used as alternative therapeutic options for Staphylococcus aureus infections. Our objectives were: (1) to define the in vitro activities of seven FQs in a collection of 434 methicillin-susceptible and 457 methicillin-resistant S. aureus from 23 European university hospitals; (2) to characterise the prevalence of mutations in the grlA and gyrA...
متن کاملQuinolone resistance in Campylobacter.
Sir, The Campylobacter Sentinel Surveillance Scheme Collaborators (CSSSC) highlight the importance of antimicrobial resistance in Campylobacter jejuni isolated in England and Wales, reiterating the previously described risk for quinolone resistance of foreign travel.1,2 Overall and foreign travel associated rates of quinolone resistance of 19% and 53% (noted as 55% in the abstract) are in keepi...
