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. It is also found as a common contaminant in pharmaceutical and cosmetics products. Vogel-Johnson Agar is prepared according to the formula devised by Vogel and Johnson and is recommended for the microbial limit test in USP. Originally it was developed by Zebovitz, as a 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. V.J. Agar is specified in the standard methods for examination of cosmetics, pharmaceutical articles and nutritional supplements. In addition, the formulation complies with recommendations by the USP for microbial limit testing.
