Intestinal infection refers to an acute Bacterial, viral, or parasitic infection of the small intestine. The scientific term used for such infections is “Gastroenteritis.” It is an extremely common condition and affects individuals of all ages.

  • Stool direct report
  • Stool culture to identify the presence of the organism in the stool
