Distribution of the <i>bab</i> genotypes in AH and KH (n = 160).

<p>Genotypes of one, two, three, or none <i>bab</i> genes are grouped into I, II, III, and IV, respectively. These classifications were made on the basis of number of <i>bab</i> genes present at locus A, B, and C. A black, white, or grey box indicated <i>babA</i>, <i>babB</i>, and <i>babC</i>, respectively. ‘-’ indicates the absence of <i>bab</i> gene at the designated loci. ‘AH%’ and ‘KH%’ indicate the frequency of each individual genotype within the specified population (n = 80) and ‘Total%’ shows the percent of the respective genotype in the overall population (n = 160). Bracketed numbers indicate the number of isolates possessing each respective genotype out of the population examined. ‘_*’ indicates genotypes containing chimeric form(s).
