Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed.

Even on the occasions of low intestinal enterococci counts, the presence of fecal pathogens was observed in some inland samples of the study.

When the presumptive colony counts ranged from 12 to 62 per membrane, the false negative rate was still relatively high, being The number of E.
