Comparison of BIOGRAM and commercial microdilution antimicrobial susceptibility test systems.
The BIOGRAM (Difco Laboratories, Detroit, Mich.) system, which is designed to calculate MICs from disk diffusion zone diameters, was compared with two commercial microdilution antimicrobial susceptibility systems. A total of 111 clinical isolates were evaluated with each test system. Six additional isolates were tested in a comparison between BIOGRAM and Sceptor (Johnston Laboratories, Inc. Tow...
متن کاملIn vitro Degradation of Antimicrobials during Use of Broth Microdilution Method Can Increase the Measured Minimal Inhibitory and Minimal Bactericidal Concentrations
The antibacterial activity of some antimicrobials may be under-estimated during in vitro microbiological susceptibility tests, due to their instability under such conditions. The in vitro degradation of seven widely used antimicrobials (amoxicillin, cephalexin monohydrate, cefotaxime sodium salt, ciprofloxacin, erythromycin hydrate, clarithromycin, and doxycycline hyclate) and its effect on MIC...
متن کاملThe association of biofilm formation and sub-minimal inhibitory concentrations of antimicrobial agents
Introduction: Although bacteria producing biofilm are more resistance to antimicrobial agents, biofilm formation can stimulated by sub-minimal inhibitory concentrations (sub-MICs) of some antimicrobial agents. Therefore, we designed present study to investigate the in vitro efficacy of several antibiotics (including ceftazidime, piperacillin, ticarcillin, carbenicillin, aztreonam, merop...
متن کاملImproved method for determining antibiotic susceptibility of Flavobacterium columnare isolates by broth microdilution.
A simple and reproducible microdilution method was developed to test the susceptibility of the bacterium Flavobacterium columnare to antibiotics in vitro. The testing was conducted at 28 degrees C for 44-48 h at two dilutions of Mueller-Hinton broth (DMHB) using a standardized inoculum, a reference isolate of Escherichia coli ATCC25922 as a quality control organism, positive and negative contro...
متن کاملVancomycin minimal inhibitory concentration from broth microdilution and Etest in respiratory tract samples of patients with ventilation-associated pneumonia.
additive effect on quinolone susceptibility.7 Though Qnr proteins and Aac(60)-Ib-cr only induce low level quinolone resistance, they are known to facilitate selection of resistancemutations in the presence of concentrations of quinolone antibiotics.8 We describe an isolate of K. pneumoniae isolate carrying three plasmid-mediated quinolone-resistant genes (qnrB, qnrS and aac (60)-Ib-cr variant) ...
