Abstract

The eficience among two media was compared: Tryptic Soy Broth with 10% salt (TSBS) and Oiolitti Cantoni Broth (OC) to detect and enumerateStaphylococcus aureus in non processed and thermical!y processed food supposed to contain injured cel!s by high temperature treatment andl or to contain smal! numbers of this microorganisms. The technique used was the Most Probable Number (MPN), supporting the recovering of Staphylococcus aureus. The OC broth medium, with its enrichment substances and lithium chloride, potassium tellurite with glycine used under anaerobic condition due to the addiction of liquid vaseline immediately before inoculation shows stronger inhibitory effect to the non S. aureus microorganisms, when compared with TSBS. Despile this, the medium showed a better capacity onrecovering S. aureus, showed als o a smaller number of false positives when compared to the TSBS.
