What is the relationship between Nitrites and E.coli?

Answer 1

Answer: Diagnosis: The presence of nitrites in the urine confirms the urinary tract infection.

Explanation:

Treatment: The urinary tract infection will be concerned with the antibiotic therapy to kill the bacteria producing excess nitrites. Educating K.N. about the risk factors associated with the multiple sex partners and transfer of bacteria through sexual contact.
