**8.4 Chronic bacterial prostatitis**

Prostatitis is the inflammation of the prostate gland which possibly occurs due to the microorganisms that have ascended from the urethra or by the reflux of infected urine into prostatic ducts which vacates into the posterior urethra. Once the microbe gets entered in the prostatic duct, they start multiplying rapidly and can form sporadic micro-colonies and biofilms which gets adhered to the epithelial cells of the system of ducts. Microbes responsible for this infection are *E. coli, P. aeruginosa*, species of *Klebsiella*, *Proteus, Serratia*, *Bacteroides,* etc. [5].
