Studies have shown women tend to get urinary tract infections (UTIs) more frequently than men. This is because the distance between the bowels to the urethra in women is shorter.
Consequently, UTIs are the most common infectious disease in women: One-third of women in the United States are diagnosed with at least one UTI that requires medical treatment before the age of 24.
However, many women are finding it difficult to manage this disease, as an increasing amount of UTIs are resistant to sulpha drugs -- medications used commonly to treat the infections. According to studies, these multi-drug-resistant UTIs may be linked to an unlikely source: Eating meat from cattle infected with a multi-drug resistant strain of E. coli bacteria. (E. coli is a source of well-recognized food-borne bacteria infections.)
Making a Discovery
In the late 1990s a team of researchers tallied UTIs treated at the Berkley campus student-health center and discovered nearly one quarter of the infections were resistant to sulfa drugs. Though this finding was not surprising, another was: About half of the infections were caused by an identical strain of E. coli.
After analyzing UTI infections at eight other clinics across the United States, researchers discovered more groups of people infected with the same UTI-causing bacteria that had been presented at Berkley. It was at this point when researchers realized the drug-resistant infection clusters were suspiciously similar to that of food-borne diseases, leading studies to focus on farm animals as the source of infection. And, after searching for an E. coli strain similar to the one linked to the cluster of UTIs, researchers uncovered that a single E. coli strain taken from a cow 17 years ago was nearly identical to the UTI strain they'd been studying all along.
While the findings don't offer definite proof that UTIs stem from food-borne bacterium, it is highly suspected that antibiotic resistance is transferred between animals and humans. It is also recommended that, in order to steer clear of UTIs, people should practice "commonsense hygiene" such as:
- Wiping from front to back after bowel movements
- Drinking plenty of water to flush any bacteria present from the urethra
