Final answer:
Proteus mirabilis is a bacterium that can cause urinary tract infections. It adheres to the urinary tract, invades bladder cells, and produces virulence factors that can cause inflammation and tissue damage. It can also form biofilms.
Step-by-step explanation:
The Proteus mirabilis bacterium is a common cause of urinary tract infections (UTIs). Its effect on the body includes adhesion to the urinary tract, invasion of bladder cells, and the production of virulence factors that can cause inflammation and tissue damage. Proteus mirabilis can also form biofilms, which can make it more resistant to antibiotics.
