PCDH8 and infection: A significant co-occurrence was observed in a set of B2 and F strains for pap genes (papAH, papC, papEF), encoding proteins of the fimbria favoring the ascension of the urinary tract and promoting colonization and infection, sat, which is associated with a cytopathic secreted autotransported toxin exerting effect, kpsMTII, the marker of K2 capsular polysaccharides, which plays a main role in pathogenesis, chuA (heme receptor), yfcV (Yfc fimbria), along with fyuA, malX, usp, ompT (Figure 3; Figure 6).
