Overview
Pathophysiology
Pathogenesis
Infectious colitis occurs following invasion of colonic mucosa or attachment to the colonic mucosa by a micro-organism causing inflammation
Pathogenesis of Infectious colitis
- Enteric organisms that cause colitis are usually transmitted through fecal-oral route especially in children. As few as 100 bacterial cells can be enough to cause an infection.[1]
- May also occur following antibiotic use, especially broad spectrum antibiotics.
- Can also be acquired as a sexually transmitted infection (STI) among individuals who practice unsafe anal sex especially among men who have sex with men (MSM)
- In MSM the pathogens are transmitted directly through overt or microabrasions in the rectal mucosa or indirectly during oral-anal contact.[2]
The pathogenesis, gross and microscopic pathology of infectious colitis will depend on the causative organism as follows:
- Shigella spp.
- Campylobacter jejuni
- Clostridium difficile
- Escherichia coli
- Nontyphoidal Salmonella
- Entameoba histolytica
- Chlamydia trachomatis
- Cytomegalovirus
- Yersinia enterocolitica
