What Is Cystitis?
3. Non-Bacterial Cystitis
Other microorganisms besides bacteria also cause cystitis. When adenovirus or cytomegalovirus infect the lower urinary system, they cause a more serious form of the illness that causes the lining of the bladder to bleed. This is a rare condition that is generally seen only in immunocompromised patients, such as those undergoing cancer treatment.
Candida, the microorganism responsible for yeast infections, also causes cystitis. Cryptococcus and aspergillus are other fungi that infect the kidneys of patients with diabetes, especially those who use catheters. In some tropical areas, parasitic flatworms penetrate the skin and develop inside the bladder where they lay eggs and cause inflammation.
