A fecal culture is a bacteriological analysis performed on a stool sample. The stool is collected in a container and then cultured in the laboratory to detect the presence of a germ responsible for a bacterial infection. It is recommended in cases of persistent diarrhea, food poisoning, or suspected bowel disease. The bacteria most often sought are those responsible for Salmonella, Clostridium difficile, cholera, or campylobacter. The fecal culture can be paired with parasitological research of the stool in cases of unexplained diarrhea.
