In a breakthrough, US researchers found that women's bladder is not a sterile place and may contain beneficial and deadly bacteria, a finding that could lead to better diagnostic tests for urinary tract infections ( UTI).
demystified the common belief that urine in healthy women is sterile, and has shown that bacteria are "shared" between the bladder and the vagina. The microbiota includes pathogens such as E. coli and S. anginosus as well as beneficial bacteria such as L.iners and L.crispatus. Beneficial bacteria residing 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 reevaluate everything we thought we knew about the bladder, and that's what we do," said Alan J Wolfe, a microbiologist at Loyola University of Chicago. This discovery is expected to change the way we observe pelvic floor bacteria by allowing new research and by offering new diagnostic and treatment options for urinary tract infections, urinary incontinence and urinary incontinence. Other disorders of the associated urinary tract. "
the study, published in Nature Communications, the team sequenced the genes of 149 bacterial strains of nearly 100 women. While the microbiota (community of microorganisms) found in the bladder and vagina were similar, they were distinctly distinct from the microbiota found in the gastrointestinal tract. It seems that the bacteria move between the bladder and the vagina, creating a niche of microbiota. Urination provides an obvious way for bacteria to travel from the bladder to the vagina.
But the way in which bacteria can travel from the vagina to the bladder is mysterious, especially since most bacteria studied whip-like structures) or pili (grapples) that would allow them to move, the researchers said.
