All About Colon Infection

The colon is a long, coiled, tubelike organ that reabsorbs or removes fluids from the digested food. The remaining solid waste, called stool, moves through the colon to the rectum and is finally expelled out of the body through the anus. The colon is a common site of infection by bacteria, viruses or parasites. Colon Infections can also be called as colitis or inflammation of the colon.


Colon infections can be caused by bacteria or viruses. Contaminated water, food, or poor hygiene are some of the ways how these pathogens might enter your body. Common pathogens tested are Microorganisms like Salmonella, campylobacter, Shigella, Escherichia coli (E. coli) as well as parasitic infections such as Amebiasis and Giardiasis .
