Description |
GN Broth (Gram Negative Broth) is an enrichment and selective medium for enterobacteria, with a strong inhibitory action against gram-positive because of its high content of citrate and deoxycholate. On the other hand, mannitol restrains the growth of Proteus and facilitates the proliferation of Salmonella and Shigella. The medium is strongly recommended for primary enrichment, 14-16 first hours, before going to selective media such as EMB (Ref. 01-068) or MacConkey (Ref. 01-118). Its author, Hajna, declares an extraordinary selectivity of the medium, whatever may the origin of the sample, if everything is kept in a transport medium upto the inoculation. |
