SANDOVAL, Marisol et al. Neisseria Gonorrhoeae Susceptibility to ß-lactamics Antibiotic, Tetraciclines, and Quinolones. Kasmera [online]. 2007, vol.35, n.2, pp.118-126. ISSN 0075-5222.

Neisseria gonorrhoeae susceptibility to ß-lactamics antibiotic, tetraciclines, and quinolones was studied in strains isolated from patients with gonococcic cervicitis and/or urethritis that were to consultation of Infections of Sexual Transmission of The Ambulatory Urban type II, in a neighborhood of Ciudad Bolívar from July to August - 2003. The samples were seeded in Agar Blood, GC Agar Base and 1% defined growth supplement, Agar Thayer Martin; making simultaneously a Gram stain. Suspicious colonies were identified by means of oxidase test and sugar degradation in CTA medium. The production of ß-lactamases was investigated of by means of the acidimetric method. Susceptibility tests were made in GC Agar Base and 1% defined growth supplement. Penicilline, ceftriaxone, tetracicline, and Ciprofloxacin were used. 50 strains were isolated of Neisseria gonorrhoeae that represented 43.85% of patients with gonococci infections (Urethritis and/or cervicitis) of which 82% belonged to masculine sex. There was no evidence of production of ß-lactamases in the studied strains. As far as the susceptibility to the antimicrobial drugs it was found 46% strains resistant to penicillin, 42% to tetraciclines. Ceftriaxone and ciprofloxacin showed a good activity against N. gonorrhoeae with 98 and 92% of sensitivity, respectively.
