Hemmes Medium Base, 5KG

Hemmes Medium Base is a screening medium for Salmonella and Shigella. TThe differentiation is based on seven reactions namely - dextrose, lactose, and sucrose fermentation, hydrogen sulphide production, urease detection, indole production and motility testing. Salmonella and Shigella show a red slant and a yellow butt from dextrose fermentation. Salmonella Typhimurium is motile, H2S positive indicated by blackening of the medium, indole negative and ureasenegative. Shigella are nonmotile, H2S negative, urease negative and indole negative. Appearance: Light yellow to pink homogeneous free flowing powder Gelling: Semisolid, comparable with 0.55% Agar gel Color and Clarity: Red colored, clear to slightly opalescent gel forms in tubes as slants Reaction: Reaction of 4.3%w/v aqueous solution at 25°C. pH : 7.2±0.2 Cultural Response: Cultural characteristics observed with added 40% Urea solution (FD048), after an incubation at 35-37°C for 18-24 hours
