AFLP fingerprints of <i>A. flavus</i>.

<p>Representative fingerprints are shown for 50 randomly chosen isolates. The dendrogram is based on UPGMA clustering using the Pearson correlation coefficient. The scale bare indicates the percentage similarity. The fingerprints shown are restricted to DNA fragments in the range of 50–300 nt. Indicated with arrowheads above the fingerprints are some of the invariable bands, present in all isolates, that may constitute the core-genomic elements of <i>A. flavus</i>. Indicated with arrowheads below the fingerprints are some of the variable bands enabling discrimination between individual isolates.</p

Graphical representation of the results.

<p>Minimum spanning tree representing the genotypic diversity of 149 clinical <i>A. flavus</i> isolates and a reference isolate using microsatellite typing. The MST is based on a categorical analysis of the data. Each circle represents a unique genotype. The size of the circle corresponds to the number of isolates with the same genotype. The thickness and size of the connecting bars correspond to the number of different markers between linked genotypes. The black genotype is from the reference strain <i>A. flavus</i> NRRL 3357. Genotypes with a shaded background contain 2 or more isolates with identical genotypes or contain genotypes that differ in only 1 microsatellite marker as the possible result of microevolutionary events and are likely to be clonally related.</p
