WebBefore 1990, Haemophilus influenzae type b (Hib) was the most common cause of bacterial meningitis in children 5 years of age in the United States (10, 11). During 1990 to 1998, the incidence of invasive Hib disease decreased 99% in the United States following the introduction of the Hib conjugate vaccine (5, 8). WebChocolate agar is an excellent Haemophilus growth medium, as it allows for increased accessibility to these factors. [7] Alternatively, Haemophilus is sometimes cultured using the "Staph streak" technique: both Staphylococcus and Haemophilus organisms are cultured together on a single blood agar plate. Gardnerella vaginalis is a species of Gram-variable-staining facultative anaerobic bacteria. The organisms are small (1.0–1.5 μm in diameter) non-spore-forming, nonmotile coccobacilli. Once classified as Haemophilus vaginalis and afterwards as Corynebacterium vaginalis, G. vaginalis grows as small, circular, convex, gray colonies on chocolate agar; it also grows on HBT agar. A selective medium for G. vaginalis is colistin-oxolinic acid blood agar. spice and things restaurant
