Final answer:
Option (E), The bacteria that commonly cause urinary tract infections are Proteus, Escherichia, and Klebsiella, with E. coli being the most prevalent among them.
Step-by-step explanation:
The bacteria that commonly cause urinary tract infections (UTIs) include Proteus, Escherichia, and Klebsiella. Specifically, gram-negative bacteria such as Escherichia coli (E. coli), Proteus vulgaris, and Klebsiella pneumoniae are often responsible for these types of infections.
E. coli, being an important member of the digestive tract microbiota, is the most common cause of UTIs, particularly in women. It generally causes infection when introduced to the urethra through fecal matter. Therefore, the correct answer to the question is E) A, D, and E, indicating Proteus, Escherichia, and Klebsiella as bacteria that cause urinary tract infections.
