GN BROTH MEDIUM 11 (as per IP)

Description

GN Broth is recommended by the Indian Pharmacopoeia for the selective isolation of Shigella species with subsequent isolation on a selective medium, XLD Agar.Croft and Miller isolated more strains of Shigella from rectal swabs using this medium. Taylor and Schelhart showed the superiority of GN Broth to selenite enrichment media for isolation of Shigella. Hajna also suggested the enrichment of organisms from rectal swabs in this medium 1-6 hours before plating on solid media.
