GN BROTH, HAJNA (VEG.)

GN Veg Broth is prepared by using plant based protein hydrolysate and synthetic sources and is therefore free of TSE/BSE risks. It is prepared by using Veg hydrolysate No.1 in place of Tryptose and Synthetic detergent No.III in place of sodium deoxycholate. GN Veg Broth is the modification of GN Broth can be used against conventional GN Broth, Hajna which is recommended by APHA for examination of foods. GN Broth, Hajna medium is generally used as a enteric enrichment broth for clinical specimens and as a nonselective enrichment broth for foods to recover Salmonella and Shigella species. Hajna suggested enrichment of organisms from clinical samples, like rectal swabs upto 6 hours before plating on solid media. This enrichment broth should be used in conjunction with selective and nonselective plating media to increase the probability of isolating pathogens. GN Veg Broth can be used for similar purposes.

for selective enrichment of gram-negative organisms of the enteric group
