The detection rates of five VF genes of Exotoxin (hlyA, hlyB, hlyC, hlyD, and ncf1) and eight VF genes of Adherence (papB, papC, papD, papF, papG, papH, papJ, papK) in BSI-B and UTI-U were higher than that in the ASB-U group (P < 0.05) (Table 6). Here, REG3A is linked to bacterial urinary tract infection.
