Unknown Lab Report I Example

This eliminated all gram active bacteria, and any rod-shaped bacterial species. This left the possibilities with S. Gripers, M. Rouses, M. Lutes, and S. Epidemics.

Colony morphology showed small, regular gray/white colonies. This eliminated the pigmented bacteria such as M. Rouses and M. Lutes. The FAT tube test showed the unknown bacteria to be a facultative anaerobe, which S. Epidermises is known to be. The previous two bacteria are also robes, which allowed them to be ruled out.

Following these results, Vergers Manual was used to compare the remaining sets to known findings for S. Epidermises. Only the lactose fermentation and optimum temperature tests showed discrepancies. The unknown did not produce acid when exposed to lactose.

According to Vergers Manual, 70-90% of S. Epidermises strains ferment lactose, so it was expected that the unknown would do so. Burger’s Manual also states that carbohydrate fermentation forms the basis for identifying different bootees of S. Epidermises, so it is unlikely that the unknown is a pipette that does not ferment lactose.In regards to optimum temperature, Vergers Manual states that S. Epidermises should grow optimally at ICC. The unknown showed the highest turbidity at 42 co, but because the building lost power for an unknown amount of time, it is likely that both incubators were at the same temperature, so results may have been skewed. The remaining tests were consistent with our results.

S. Epidermises is a coagulate-negative member of the Staphylococcus genus which typically lives in the skin and mucous membranes of humans.Most pieces are considered harmless, however more pathogenic strains can cause serious infections in immune-compromised individuals. Some are even important monoclonal infections. These strains produce a coaxially slime layer that forms a billion, allowing them to adhere to prosthetic valves, catheters, and shunts to possibly cause infections in patients with these implants. Infections can also occur in large wounds.

Skepticism and indoctrinations are also diseases associated with S.
