NEOGEN Muller-Kauffmann Tetrathionate-Novobiocin (MKTTn) Broth, 500 g
Supplier: NEOGEN 700004511
Muller-Kauffmann Tetrathionate-Novobiocin Broth is used for the selective and differential isolation of Salmonella spp. in a laboratory setting and is included in ISO 6579:2017. This medium is not intended for use in the diagnosis of disease or other conditions in humans. A selective enrichment medium for the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017. Mueller originally described a tetrathionate broth that inhibited lactose fermenting Enterobacteriaceae but not Salmonella. Kauffmann later modified the formulation to include ox bile and brilliant green to improve selectivity. Finally, Jeffries added Novobiocin to inhibit Proteus species. Meat extract and casein provide a source of nitrogen and amino acids and sodium chloride maintain the osmotic balance.For more information visit https://www.neogen.com/solutions/Microbiology/muller-kauffmann-tetrathionate-novobiocin-broth
