An oxidase test was whence performed and the result came back to be negative which hence direct the path to a glucose and lactose test. Those test antecede to determining whether the KIA produced hydrogen sulfide, which then took it to a PD test, bm test, a LD test, and an urea hydrolysis test, concluding that the bacteria is genus Proteus vulgaris.

It is grouped with the enterobacteriaceae and is an opportunistic pathogen of humans. It is known to cause urinary tract infections and wound infections. The genus Proteus is classified in the enteric bacteria, unitedly with Escherichia coli, Salmonella, Shigella, Enterobacter and Serratia. All these bacteria are small, Gram-negative rods and are facultative anaerobes: they ferment sugars in an oxidative conditions but can use a wide range of organic molecul! es in aerobic conditions.If you want to get a full essay, rewrite it on our website: BestEssayCheap.com
