Detection and evaluation of microbial subsets (emergence III).

<p>When only culture-positive data were analyzed (including observations collected from cows previously <i>E</i>. <i>coli</i>-positive), dimensionless indicators distinguished, with perpendicular data inflections, three non-overlapping subsets (<b>A</b>). One of such subsets was devoid of <i>S</i>. <i>aureus</i>+ observations, but predominantly composed of observations collected from previously <i>E</i>. <i>coli</i>-positive animals. When validated, such subset revealed higher M/L ratio values than the remaining subsets (<b>B</b>). The two other subsets differed in their L % values (<b>B</b>).</p>
