The results of this study show that the prevalence frequencies of CXCR1 (2608) GC and CXCR1 (2608) C in UTI patients and patients with chronic UTI are lower than those in the healthy and acute cystitis groups, but expression levels of CXCR1 in neutrophils were not different. Here, CXCR1 is linked to bacterial urinary tract infection.
