For example, bacteria from the genus Salmonella are mostly facultative anaerobes, oxidase-negative, catalase-positive and gramnegative rods. Most strains are motile and ferment glucose with production of both acid and gas.
Salmonella Typhimurium. Salmonella typhimurium is a gram negative bacteria. Commonly associated with disease, it is an organism that primarily is found in the intestinal tract.Since it requires a lower pH and a warm temperature to thrive, it will remain dormant in nature and only can reproduce inside of a host.he Salmonella bacteria have a lipopolysaccharide membrane which is a protective measure against the environment. Inside the membrane, there is a substance called Lipid A which is a toxin in some circumstances. Animals have an enzyme in their intestines which breaks down the Lipid A and makes it harmless to them.
