Identification of Gardnerella (Haemophilus) vaginalis.
Different tests for the identification of Gardnerella (Haemophilus) vaginalis and for its differentiation from catalase-negative unclassified coryneforms from the vagina were evaluated on over 200 bacterial strains, with special emphasis on optimal test conditions. A presumptive identification of G. vaginalis in the clinical laboratory can be made on the basis of colonial morphology, clear beta...
متن کاملRapid microbiochemical method for identification of Gardnerella (Haemophilus) vaginalis.
A rapid biochemical method for the identification of Gardnerella vaginalis has been developed. The method is based on the fermentation of starch and raffinose and on the hydrolysis of hippurate. With this new procedure, identification was confirmed for 390 of 396 G. vaginalis isolates within 1 h after their inoculation into the three substrates.
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...
متن کاملFactors affecting isolation and identification of Haemophilus vaginalis (Corynebacterium vaginale).
The rate of isolation of organisms resembling Haemophilus vaginalis (Corynebacterium vaginale) from vaginal specimens was not significantly affected by anaerobic versus carbon dioxide incubation atmospheres or whether specimens were inoculated on isolation media immediately after collection or after a delay of 6 h. Forty-one clinically isolated strains were provisionally divided into 30 H. vagi...
متن کاملMinimal criteria for the identification of Gardnerella vaginalis isolated from the vagina.
Vaginal swabs were examined for the presence of Gardnerella vaginalis. Of 294 isolates with appropriate colonial and cellular morphology subjected to an identification procedure, 203 (69%) were identified as G vaginalis. The 91 isolates not identified as G vaginalis were differentiated by their inability to ferment starch, cause diffuse beta haemolysis on human blood agar or hydrolyse hippurate...
