Identifying an Unknown

Introduction: There are many reasons for knowing the individuality of microorganisms. The reasons evict range from the knowing the causative agent of a disease, to knowing the correct microorganism to be utilisationd for do trusted foods or antibiotics. This study was done by applying exclusively of the methods that find been learned so far in the microbiology rivuleting background knowledge class for the identification of an uncharted bacterium. This experiment to finding the undiscovered region of #17 was performed by first ascertain whether the bacterium were a thousand positive or a gram negative. The unknown #17 came to be a gram negative. An oxidase test was whence performed and the result came back to be negative which accordingly direct the path to a glucose and lactose test. Those test conduce to determining whether the KIA produced hydrogen sulfide, which then took it to a PD test, campaign test, a LD test, and an urea hydrolysis test, concluding tha t the bacteria is genus Proteus vulgaris.

Proteus vulgaris is a rod-shaped, Gram negative bacterium that inhabits the intestinal packets of manhood and animals. It plunder be found in soil, water and faecal matter. 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 intestinal 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 molecules in aerob ic conditions.If you want to get a full essa! y, high society it on our website: OrderEssay.net
