A new rapid resazurin-based microdilution assay for antimicrobial susceptibility testing of Neisseria gonorrhoeae

Neisseria Gonorrhoeae Reference Strains for Antimicrobial Susceptibility Testing

In-vitro antimicrobial susceptibility of Neisseria gonorrhoeae in New Zealand.

Four hundred and forty-two isolates of Neisseria gonorrhoeae were tested by an agar dilution method for their susceptibility to penicillin, ampicillin, tetracycline, cephaloridine, and spectinomycin. Of these isolates, 295 were tested for their susceptibility to sulphamethoxazole and to trimethoprim by the same method, using Oxoid diagnostic sensitivity test agar plus 7.5% laked horse blood ins...

Rapid colorimetric assay for antimicrobial susceptibility testing of Pseudomonas aeruginosa.

A colorimetric assay based on the reduction of a tetrazolium salt [2,3-bis[2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide (XTT)] for rapidly determining the susceptibility of Pseudomonas aeruginosa isolates to bactericidal antibiotics is described. There was excellent agreement between the tobramycin and ofloxacin MICs determined after 5 h using the XTT assay and after 18 h u...

A Study Of The Antimicrobial Susceptibility Pattern Of Neisseria Gonorrhoeae

Background and objectives: Rapidly emerging antimicrobial resistance of Neisseria gonorrhoeae isolates to currently recommended antibiotics is a setback for effective treatment and control of disease. This study was carried out to determine the antimicrobial susceptibility profile in the isolates obtained from female sexual workers and male patients attending STI clinics in Hyderabad. Materials...

Assessment of Etest as an alternative to agar dilution for antimicrobial susceptibility testing of Neisseria gonorrhoeae.

We studied whether the Etest can be used as an alternative to agar dilution to determine antimicrobial susceptibilities of ceftriaxone, cefixime, and cefpodoxime in Neisseria gonorrhoeae surveillance. One hundred fifteen clinical and laboratory isolates of N. gonorrhoeae were tested following the Clinical Laboratory Improvement Amendments (CLIA)-approved CLSI standard agar dilution method and, ...
