Bacteria that cause urinary tract infections invade bladder cells. Scientists at Washington University School of Medicine in St. Louis have found definitive proof that some of the bacteria that plague women with urinary tract infections (UTIs) are entrenched inside human bladder cells. The finding confirms a controversial revision of scientistsâ model of how bacteria cause UTIs. Previously, most researchers assumed that the bacteria responsible for infections get into the bladder but do not invade the individual cells that line the interior of the bladder.
When bacteria enters the body due to an infection, a type of white blood cells called phagocytes will surrounds and clumps the foreign bacteria together.They will then engulf â¦ the bacteria and digest them. One of the phagocytes would regurgitate parts of the ingested material of the bacteria back to its surface.f an infection occurs and bacteria enters your body the white blood cells will produce antibodies to cover them and clump them together, then more white blood cells will engu â¦ lf them and digest them.
