Infectious Diseases


A gastrointestinal infection (gastroenteritis) is any infection caused by a virus, bacteria, or parasite that causes inflammation of the gastrointestinal tract (GI) and has the characteristic symptoms of excessive, watery diarrhea and stomach pain. Diagnosis of the responsible intestinal pathogen requires the detection of the organism in the feces, duodenal fluid, or small intestine using biopsy specimens. Meridian offers a range of antigens and antibodies to gastrointestinal pathogens, which have been validated in various types of immunoassays.
