Looking into the FQR clones implicated in UTI, we found a wide diversity of PG-CH combinations, some of them shared in both uUTI and cUTI, such as A (CH11-54), B1 (CH65-32), B2 (CH14-64), B2 (CH38-15), B2 (CH40-41), or D (CH37-27). The gene discussed is C4B; the disease is bacterial urinary tract infection.
