Salmonella are gram-negative, rod-shaped bacilli that can cause salmonellosis, a diarrheal illness in humans.
Gram-negative bacteria usually have a cell wall composed of a thin layer of peptidoglycan, covered by a membrane.
There are over 2,300 subtypes of the Salmonella enterica bacterium, including serovars enterititis, Salmonella Agbeni, and typhimurium.
The bacteria live in the gut of infected humans and animals. Some animal and human strains can make humans sick.
Salmonella is a major cause of human bacterial infections in the United States (U.S.). According to the Centers for Disease Control and Prevention (CDC), it affects around 1 million Americans every year, leading to 19,000 hospitalizations and 380 deaths.
