ARAF and urinary tract infection: As a control, we PCR-amplified the same set of genes using the DNA from single bacterial isolate, IHE3034, which is pks+, and EC640, which is tcpC+ and usp+, which was initially obtained from the urine of a 5-month-old patient with a urinary tract infection at the University of Puerto Rico Pediatric Hospital and was found to be positive for all three genes (Wolter et al., 2009).
