WebIntroduction of Haemophilus influenzae Haemophilus influenzae colonies on chocolate agar after overnight incubation in a carbon dioxide atmosphere as shown above image. It must contain haemin or other iron … Members of the genus Haemophilus usually will not grow on blood agar plates, as most species require at least one of these blood factors for growth: hemin (X-factor) and/or nicotinamide adenine dinucleotide (V-factor). They are unable to synthesize important parts of the cytochrome system needed for respiration, and they obtain these substances from the heme fraction, known as the X factor, of blood hemoglobin. The culture medium must also supply the cofactor nicotinamide ad…

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
