This microbe is a Gram negative rod-shaped bacterium which is associated with gastrointestinal disease called salmonellosis, characterized by cramping and diarrhea. It is more commonly encountered in developing countries. Some strains are implicated in enteric fever, where the microbe becomes more systemic to produce typhoid-like symptoms – fever, malaise, abdominal pain, etc. Victims can be humans and other animals. The rods are straight and usually motile. Gas is produced when fermenting sugars; hydrogen sulfide is rarely encountered. Growth occurs optimally at 35-37 C.
