In a breakthrough, US researchers found that women's bladders are not a sterile site and may contain both beneficial and deadly bacteria, which could lead to better diagnostic tests for UTI
. She refuted the widespread assumption that urine is sterile in healthy women and showed that these bacteria "split" between the bladder and the vagina and the microbiota Pathogens such as E. coli and S. anginosus as well as useful bacteria such as L.iners and L. Crispatus.
The beneficial bacteria found in both the bladder and vagina could provide protection against urinary tract infections.
"Now that we know that the bladder is not sterile, we need to re-evaluate everything we knew about the bladder, and that's exactly what we're doing," said Alan J. Wolfe, microbiologist at Loyola University Chicago.
This finding "should change the way we view the bacteria of the female pelvic floor by enabling further research and new diagnostic and therapeutic options for urinary tract infections, urinary incontinence, and other related urinary tract diseases," the researchers said [1
While the microbiota (community of microorganisms) in the bladder and vagina were similar, they differed markedly from the microbiota found in the gastrointestinal tract.
It seems that bacteria migrate between the bladder and the vagina and effectively generate a microbiota niche.
Urination is an obvious way for bacteria to get from the bladder to the vagina.
However, it is a mystery how bacteria can pass from the vagina to the bladder, as most of the bacteria studied in the study do not have such features as flagella (whip-like structures) or pili (grappling hooks) that would enable them to to move, the researchers said.
