Introduction The purpose of this project was to detect which organism we had in our unknown mixed culture tube by running a series of experiments to detect which specific Gram negative organism we had. To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps

Biological weapons are intended to deliberately disseminate disease producing organisms or killing toxins in food‚ water by aerosol. Bacillus anthracis‚ the organism that causes anthrax‚ has been bandied about the media and the American public has been intrigued by stories and cases and fatalities and the next story. One agent not often discussed but every bit as horrifying as anthrax

all humankind‚ given it’s way. With the Europeans trading with the East‚ a rumor was being spread that an infectious disease was forming in Asia. In Jordan McMullin’s book‚ “The Black Death”‚ he discusses‚ “By September of 1345‚ the Yersinia pestis bacillus‚ probably carried by rats‚ reached the Crimea‚ on the northern coast of the Black Sea‚ where Italian merchants had a good number of trading colonies.” Everyone talks about how the spread of the Black Plague happened or how horrible the symptoms to

Bartonella henselae is the bacterium that causes cat scratch disease Bartonella henselae is a small gram negative- bacillus. It is an aerobic organism ~1µm in length and ~ 0.5 µm in diameter‚ that occasionally takes a slightly curved shape. It makes small jerking movements in the fresh state‚ but has no whips.1 Optimal growing conditions are blood (5%)‚ moist atmosphere

internal metabolism10. This offers stability‚ ability to regenerate cofactors‚ reusability and ease of solid-liquid separation. Individual researchers have performed whole cell immobilization on Streptomyces griseus‚ Microbacterium liquefaciens‚ Bacillus sp.‚ Pseudomonas and serratia marcescens‚ a possible indication that this technique is as capable as the enzyme immobilization7. Furthermore‚ whole cell immobilization technique protects immobilized cells against potentially toxic substrate by entrapping

It is a common cause of antibiotic-associated diarrhea (AAD). It accounts for 15-25% of all episodes of AAD.” [1] The two toxins produced by C. diff are toxin A and toxin B. “Toxin A is an enterotoxin
