This family of bacteria is often associated with urinary tract infections?
a) listeria
b) salmonella
c) proteus

The correct answer is C) Proteus

Explanation:

Proteus comes under the family Enterobacteriaceae and is often associated with urinary tract infections in animals and humans. These bacteria are often the part of intestine but become pathogenic when enter into urinary tract.

Proteus mirabilis is a gram negative anaerobic bacteria present as normal flora of intestine known to cause urinary tract infections in humans but most of the urinary tract infection is caused by E. coli.

When these bacteria get into the blood stream they can cause systemic inflammatory response syndrome and sepsis which has very high mortality rate.
