Hardy Diagnostics Novobiocin NaCl is a selective supplement intended for use in conjunction with Shigella Broth Base for the selective enrichment of Shigella spp. in foods as recommended by the APHA.(1)
are gram-negative, non-motile, non-spore forming rod-shaped bacteria
closely related to
Salmonella. Shigella infection is typically via ingestion (faecal-oral contamination), depending on age and condition of the host, and as few as injestion of 10 cells can be enough to cause an infection. Shigella causes dysentery, resulting in the destruction of the epithelial cells of the intestinal mucosa in the cecum and rectum. Some strains produce enterotoxin and Shiga toxin, similar to the verotoxin of E. coli O157:H7.(4) Shigella Broth Base (Cat. no. C9151) is used in conjunction with Novobiocin NaCl for the selective isolation and cultivation of Shigella species as recommended by APHA.(1,3) Novobiocin is inhibitory to gram-positive bacteria, such as Staphylococcus aureus, and certain gram-negative organisms like Haemophilus influenzae and some strains of Proteus.(1,2)
