Haemophilus vaginalis (Corynebacterium vaginale, Gardnerella vaginalis) in a family planning clinic population.

Relative incidence of Corynebacterium vaginale (Haemophilus vaginalis), Neisseria gonorrhoeae, and Trichomonas spp. among women attending a venereal disease clinic.

Method for isolation and identification of Corynebacterium vaginale (Haemophilus vaginalis).

A method for the clinical isolation and recognition of Corynebacterium vaginale (Haemophilus vaginalis) is presented. Wet mount and stained characteristics of genital tract discharges, cellular and colonial morphology of the bacilli, inhibition by H(2)O(2), lack of a catalase, and fermentation of particular carbohydrates are the determinant factors. The method enables differentiation of the spe...

Tellurite reduction test to aid in the recognition of Corynebacterium vaginale.

Corynebacterium vaginale (Haemophilus vaginalis) does not reduce potassium tellurite. When a 1% aqueous solution of tellurite is added to starch agar plates previously inoculated with vaginal discharge material, other starch-fermenting and most non-starch-fermenting bacteria rapidly reduce tellurite to produce black or gray colonies. This test is a useful adjunct to methods for rapid presumptiv...

Metronidazole in treatment against Haemophilus vaginalis (Corynebacterium vaginale).

The rate of bactericidal activity and inactivation of metronidazole was studied in time-kill curves with Haemophilus vaginalis (Corynebacterium vaginale). The minimum inhibitory concentrations of metronidazole for the eight strains tested ranged from 4 to 16 micrograms/ml. At a concentration of 20 micrograms/ml, metronidazole demonstrated a slow cidal effect against exponential-phase organisms,...

Comparisons between direct microscopic and cultural methods for recognition of Corynebacterium vaginale in women with vaginitis.

The frequency with which clue cells could be detected in Gram-stained vaginal smears and/or cervical Papanicolaou (Pap) smears was compared with the frequency of Corynebacterium vaginale (Haemophilus vaginalis) isolation in a group of 236 female patients, of whom 221 had vaginitis. Vaginal clue cells were found most often in women from whom C. vaginale was isolated (P = 0.00006) whereas, conver...
