It occurs mainly in the tropical regions and is a main cause of morbidity and mortality, particularly in young children and adults. Evidence Acquisition: One of the major causes of diarrheal diseases is bacteria; detection of pathogenic bacteria is a global key to the prevention and identification of food-borne diseases and enteric infections (like diarrhea).
