Product Code TM 2420
Vogel-Johnson Agar Base w/ 1.5% Agar is prepared according to the formula devised by Vogel and Johnson and is recommended for the selective isolation of coagulase positive, mannitol fermenting Staphylococcus aureus from heavily contaminated foods in accordance with FDA BAM, 1998. Staphylococcus aureus, a gram-positive, spherical bacterium, is a common colonizer of the human skin and mucosa. It causes skin and wound infections, urinary tract infections, pneumonia and bacteremia. It is also commonly implicated in food poisoning and as a common contaminant in cosmetics and pharmaceutical products. Originally it was developed by Zebovitz, as Tellurite Glycine Agar, a selective medium for the detection of coagulase-positive staphylococci. Vogel-Johnson modified the medium in 1960 by the addition of phenol red as a pH indicator and by increasing the quantity of mannitol. Selection and differentiation of coagulase-positive staphylococci on V.J. Agar is based on mannitol fermentation and tellurite reduction. Vogel-Johnson Agar Base w/ 1.5% Agar can also be used in the enumeration and identification of microbes from cosmetics wherein Staphylococcus contamination is expected.
