Predominance of Vancomycin-Sensitive Strains of Neisseria gonorrhoeae in Djibouti. (Reannouncement with New Availability Information).

摘要

During late summer, 1988, workers at the Centre for Hygiene and Epidemiology (a national STD reference centre in Djibouti) became concerned by a sharp decrease in the isolation rate of N. gonorrhoeae, despite their use of recommended bacteriological procedures. This decline in culture sensitivity continued into 1989, despite suggestive gram stains of urethral swabs. In February, 1989, we analyzed urethral swabs from 24 Djiboutian men with urethral discharge. The gram stain was suggestive of gonococcal infection in 19, but no strains of N. gonorrhoeae could be recovered on MTM agar, a commercially available (Difco, Detroit, MI) selective agar medium containing vancomycin, colistin, nystatin, and trimethoprim. However, when chocolate agar was subsequently included in the isolation procedure, two strains of N gonorrhoeae were isolated from the last three gram-stain-positive specimens.
