The sources of infection are diseased animals. The pathogens are transmitted to humans in food. The diseases are sometimes also communicable among humans. The pathogens are identified for diagnostic purposes in stool cultures using special selective mediums. Helicobacter pylori contribute to the pathogenesis of type B gastritis and peptic ulcers. Spirillum minus causes rat bite fever, known as sodoku in Japan where it is frequent. ■
