Additionally, the pilA gene was noted more frequently among the strains derived from gastrointestinal tract infections when compared to the strains isolated from respiratory (0.0250), bloodstream (0.0229) or skin and soft tissue infections (0.0394), and when compared to the pilB gene frequency among the strains isolated from the gastrointestinal tract (0.0389). Here, HIVEP2-DT is linked to digestive system infectious disorder.
