<p>Detected recombination events.</p>

The table lists the recombination events detected within the 81 unique fimbrial subunit gene sequences using RDP5 [40]. Fimbrial subunit genes with a recombination event (Recombinant) are listed along with the contributing genes (Major Parent, Minor Parent). The representative nucleotide and protein sequence names, and N-terminal region sequence group (see Supplemental Table 2, Table 5) are listed for each recombination event. The “Found In” column lists the number of times the identified recombination event occurred in the gene sequences analyzed. The “+” in the “Detection Methods” column indicates the evaluation method that detected the recombination event (R = RDP, G = GENECONV, B = BOOTSCAN, M = MAXCHI, C = CHIMERA, S = SISCAN, T = 3SEQ).
