What Is Cystitis?
Reviewed: Dr. Gromatzky
2. Bacterial Cystitis
Bacterial infection occurs either when bacteria from the outside enter through the urethra, or those naturally on the inside grow out of control. Types most often encountered include Escherichia coli and Enterobacter. Most are bacteria found on a patient’s own body.
Rarer bacteria can cause more serious infections. One type is mycobacteria, a genus responsible for diseases like leprosy and tuberculosis. Another is chlamydia, a sexually transmitted disease that behaves much like a virus. Bacteroides fragilis is a bacterium from the colon that can survive without oxygen and is resistant to most antibiotics.
