GI AND OTHER INFECTIONS

The stomach is an important organ in the body. It plays a vital role in digestion of foods, releases various enzymes and also protects the lower intestine from harmful organisms. 

Many stomach diseases are associated with infection. However, a large number of studies have indicated that most cases of stomach ulcers, gastritis and indigestion are caused by Helicobacter pylori infection.

There are many causes of infectious diarrhea, which include viruses, bacteria and parasites. The bacterium Campylobacter is a common cause of bacterial diarrhea, but infections by Salmonellae, Shigellae and some strains of Escherichia coli (E.coli) are frequent.

Giardiasis is a parasitic disease caused by the flagellate protozoan Giardia lamblia. The giardia organism inhabits the digestive tract of a wide variety of domestic and wild animal species, as well as humans.
