Selectively isolate group B streptococci from clinical specimens containing mixed flora using Thermo Scientific™ Todd Hewitt Broth with Gentamicin and Nalidixic Acid (Trans Vag Broth).

Remove the need for pipetting, dispensing or autoclaving with convenient, pre-filled and ready-to-use tubes of Todd Hewitt Broth with the addition of Gentamicin and Nalidixic Acid to inhibit growth of some gram-negative bacteria. Requires the addition of 0.25mL of 5% sheep blood per tube before use to increase recovery of group B streptococci.

Streptococci are facultatively anaerobic, catalase-negative, gram-positive cocci that occur as pairs or chains. They cause a wide variety of clinical diseases including pharyngitis, scarlet fever, otitis media, impetigo, meningitis, neonatal sepis, pneumonia, endocarditis, osteomyelitis, and necrotizing fascitis. One of the most useful phenotypic characteristics of streptococci is the hemolytic reaction, generally classified as alpha, beta or gamma according to the appearance of zones around colonies growing on Blood Agar. Beta-hemolytic streptococci are further characterized by Lancefield groups based on the antigenic differences in group-specific polysaccharides located in the bacterial cell wall.
