چکیده
A new differential medium for isolation of Corynebacterium vaginale is described. This opaque medium containing 1% corn starch allows detection of C. vaginale by the zones of clearing developing around the colonies.

Comparative isolation of vaginal yeasts on selective and nonselective media.
The isolation of vaginal yeasts was compared on a selective medium, phosphomolybdic acid agar, and on starch agar, a nonselective differential medium used primarily to isolate Corynebacterium vaginale. The majority of the Candida albicans strains were isolated on starch agar, but the selective medium was required for isolating all yeasts from the greatest number specimens.
متن کاملMethod 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...
متن کاملComparisons 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...
متن کاملRapid identification of Corynebacterium vaginale in non-purulent vaginitis.
A simple set of tests is proposed to give excellent probability for the identification of Corynebacterium vaginale from clinical material. Using these tests, 380 C vaginale were isolated from genital tract specimens from 1402 patients. Of these isolates 70 were from symptomatic patients. These 70 isolates were subjected to a further set of tests to confirm their identity. The advantage of these...
متن کاملTellurite 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...
