The Enterobacteriaceae are a large family of gram-negative bacteria that are commonly found in the intestines of humans and animals. They include many genera like Escherichia, Shigella, Salmonella, Klebsiella, and others. Some species are normal gut flora while others are pathogenic. These bacteria can be identified based on their biochemical reactions and antigenic structures.
