Example sentences for: β-hemolysis

How can you use “β-hemolysis” in a sentence? Here are some example sentences to help you improve your vocabulary:

Direct genomic sequencing of the sagA/pel ::Tn 917 insertion junction in these kidney-recovered β-hemolysis positive variants established that the transposon was present in the genome in exactly the same location as the parental β-hemolytic negative sagA/pel mutant.
This prediction was tested experimentally and the β-hemolysis positive sagA/pel variant was found to be as virulent as the wild type isolate in the skin infection model (see figure 5).
Previous studies from our laboratory have consistently demonstrated loss of the SpeB phenotype in S. pyogenes isolates injected in a skin air sac and recovered from the organs of lethally infected mice [ 10 16 ] . This selection was not associated with loss of β-hemolysis but was associated with over-expression of M and M-related proteins, which in turn are predictive of the invasive potential of the organism in a skin infection model [ 16 ] . Based on the phenotypic characteristics of the kidney-recovered variant (β-hemolytic positive, M and M-related protein positive and SpeB negative) we predicted that this variant would be as virulent or more virulent than the wild type organism in the mouse skin infection model.
This result indicated additional levels of regulation of the β-hemolysis phenotype could be selected by biological pressures in the mouse.
To recover a β-hemolysis positive variant, from the mouse kidney, with the transposon in its original position was unexpected.
