Vaccine for Urinary Tract Infections?

For several decades, scientists have been attempting to develop a vaccine for the common UTI. The only problem is, that UTIs are caused by more than one type of bacteria and there are many risk factors for developing UTIs. UITs affect more than 50% of women at least once in their lives. This leads to a lot of medical costs, lost work days and emergency room visits.

Escherchia coli (E. coli) is the most common pathogen leading to UTIs. There are many types of E coli that exist. Certain bacteria express certain proteins that act as anchors that allow them to easily attach to urogenital mucosa and creep into the urethra and bladder. Recently, researchers at Univ. Michigan developed a vaccine against E coli using certain iron receptors on the bacteria against which the patient’s immune system can react. The vaccine is administered in the nose and is currently in phase 1 trials.

Each year, there are approximately 73,000 cases of E. Coli. This number may seem low in comparison to other infections, but in knowing how preventable it is; it is a big number. After reading through your website, it is clear that your organization has the same passion for E. Coli awareness, as Here, at (a non profit website dedicated to the preventions and treatments of diseases) we realize how important establishing awareness is. That is why we have worked with several elite non profit organizations in the past. If you could, please list us as a resource or host our social book mark button, it would be much appreciated. Together, we can turn 73,000 into 0.If you want more information on that please email me back with the subject line as your URL.
