Flexi Says: Bacterial infections of the urinary tract are very common. Typical organisms that cause UTIs include Escherichia coli and Staphylococcus saprophyticus. These organisms may infect any part of the urinary tract. Bacteria is present in the genitals may enter the urethra and then to bladder causing infection. This can happen during sexual activity. Women are more prone to urinary tract infections than men. This is because the urethra is shorter in case of women than in men, therefore the infection causing bacteria have a shorter distance to travel. Thus, the bacteria can easily reach the bladder in case of women.
