Gastrointestinal (GI) tract infections with viruses, bacteria, and parasites are among the main causes of gastroenteritis, the inflammation of the lining of the stomach and the intestines.
Diarrhea is a common symptom of gastroenteritis. Globally, diarrheal disease is the second leading cause of death in children under five years old, killing 525,000 children every year. 
Molecular diagnostics, such as real-time PCR assays, have shown higher sensitivity, specificity, and positive predictive value than culture, allowing more accurate detection of enteropathogenic bacteria to support effective patient outcomes.
