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 this bacterium is "shared" between the bladder and the bad and 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 the bad 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 idea "should change the way we look at female pelvic floor bacteria by allowing new research and by offering new diagnostic and treatment options for urinary tract infections, urinary incontinence." urgency and other badociated urinary disorders ".
For the study, published in Nature Communications, the team sequenced the genes of 149 bacterial strains from nearly 100 women.
While the microbiota (community of microorganisms) found in the bladder and bad were similar, they were distinctly distinct from the microbiota found in the gastrointestinal tract.
It seems that bacteria travel between the bladder and the bad. a microbiotic niche.
Urination provides an obvious way for bacteria to travel from the bladder to the bad.
But the way bacteria can travel from the bad to the bladder is mysterious, especially since most bacteria studied like flagella (bad-shaped structures) or pili (grapples) that would allow them to to move, the researchers said:
