Salmonella
Salmonella /ˌsælməˈnɛlə/ is a genus of rod-shaped (bacillus) bacteria of the Enterobacteriaceae family. There are two species of Salmonella, Salmonella bongori and Salmonella enterica. Salmonella enterica is further divided into six subspecies and over 2500 serovars.Salmonellae are found worldwide in both cold-blooded and warm-blooded animals, and in the environment. Strains of Salmonella cause illnesses such as typhoid fever, paratyphoid fever, and food poisoning (Salmonellosis).
