Comparison of the Detection Effect of Three Chromogenic Media of Staphylococcus aureus

Abstract:

Two current main chromogenic media products of abroad and the newly developed PEN-TCF from Guangdong Huankai Microbial Sci. & Tech. Corporation were compared in this study. Their recovery of different Staphylococcus aureus strains, minimum detection limits and the recovery, specificity and anti-distubance of detecting artificial contaminated samples were studied. The results showed that 3 media had similar minimum detection limits, Chromogenic Media A and PEN-TCF had better sensitivity but worse anti-distubance, while Chromogenic Media B had better anti-distubance yet lower sensitivity, and Media B and PEN-TCF were more specific than Media A.
