Salmonella

Also known as salmonella bacteria

Salmonella is a genus of rod-shaped, (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two known species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,650 serotypes. Salmonella was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon.

AI overview

Salmonella is a genus of rod-shaped bacteria that can be found in the family Enterobacteriaceae, with two known species—Salmonella enterica and Salmonella bongori—that together contain thousands of different serotypes. It matters because Salmonella enterica is a significant pathogen affecting both humans and animals, which is why it was named after Daniel Elmer Salmon, an American veterinary surgeon who studied diseases in livestock.

Salmonella species are non-spore-forming, predominantly motile enterobacteria with cell diameters between about 0.7 and 1.5 μm, lengths from 2 to 5 μm, and peritrichous flagella (all around the cell body, allowing them to move). They are chemotrophs, obtaining their energy from oxidation and reduction reactions, using organic sources. They are also facultative anaerobes, capable of generating adenosine triphosphate with oxygen ("aerobically") when it is available, or using other electron acceptors or fermentation ("anaerobically") when oxygen is not available.
