A urine culture is a laboratory method used to examine urine samples to look for microbes. It follows that determining if there is a urinary tract infection or not by noticing bacterial growth and counting their colonies in culture media identifies the type of bacteria. It was found that Escherichia coli is the most common pathogen causing UTI due to its existence in the large intestine, thus in the anal canal, which is close to the urethra and thus can move out easily into the urinary tract, as well as other gram-negative bacilli, accordingly determine the appropriate antimicrobial treatment. In a total of 24 urine samples collected and tested by conventional culture, significant growth was detected in 2 (16%), no significant growth was found in 8 (66%), and 2 (16%) showed no growth at all in females, while in males, 3 (25%) of the samples show overall no significant growth and 9 (75%) show no growth at all. In addition, we conclude that females have a higher rate of bacterial growth than males due to their anatomical structure; therefore, they suffer from urinary tract infection more than males.
