چکیده

The 2-U penicillin and microgram oxacillin discs proposed for screening meningococci for susceptibility to penicillin were evaluated by using MICs measured by the E test. The discs yielded unacceptably high frequencies of misclassification of susceptibility category and should be abandoned in favor of MIC estimations. An agreed breakpoint for reduced penicillin susceptibility in meningococci is needed for the E test.

Serogroups and antibiotic susceptibility patterns of Neisseria meningitidis isolated from army recruits in a training camp.

Invasive Neisseria meningitidis infection is rare but carries a high mortality rate. The carriage rate in the normal population is around 10% and can be higher in confined populations. A study on the prevalence of carriage of N. meningitidis was conducted among 3195 army recruits after 2 months of intensive training in an army camp. N. meningitidis was isolated from 37.0% of these recruits. Two...

In vitro susceptibility of Neisseria meningitidis.

Sir, Reduced susceptibility of Neisseria meningitidis to penicillin (MICs 0.12 mg/L) in the UK was reported by Jones & Sutcliffe in 1990 to be at a level of 3%, comparable to that found in 1987. We have recently undertaken an in vitro study to investigate the susceptibility of meningococci from our collection of strains, to a variety of antimicrobial agents, including penicillin, using BSAC met...

Comparison of Disc Diffusion and E test methods for Antimicrobial Susceptibility Testing Of Vancomycin in Coagulase Negative Staphylococcus Isolated from Blood Culture

  Background and Objective: Reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (CoNS). The objective of the present study was to compare and evaluate the performance of disc diffusion and E test (Epsilometer test) methods for antimicrobial testing of coagulase ne...

False penicillin resistance in Neisseria meningitidis following direct susceptibility tests from blood cultures.

Blood cultures drawn from a patient with clinically diagnosed invasive meningococcal disease, who had been previously administered benzylpenicillin, had beta-lactamases added to increase the probability of recovery of the causative organism. The blood cultures subsequently yielded Neisseria meningitidis but direct susceptibility tests by the comparative disk diffusion method demonstrated greatl...
