organism you think it may be. That is why eighteen different tests are performed so that you can compare your results with the table of possible unknowns. My unknown bacterium after performing the tests and comparing the charts is identified as Bacillus cereus. Bacillus cereus is a bacterium that grows best around 30-37°C. B. cereus cannot grow in high acidic‚ below pH of 4.5‚ or high alkaline environments of a pH above 9.3. You are likely to find this organism in the soil. This bacterium is able to form

Anthrax is an infectious disease and it is caused by Bacillus anthracis. It is also called Splenic Fever‚ or Charbon. There are three types of Anthrax‚ there is cutaneous (anthrax of the skin‚) inhalation anthrax‚ and gastrointestinal anthrax. Anthrax is a large‚ rod shaped bacterium. It mostly affects animals but also can be transmitted to humans. Anthrax’s first incident was in 1500 B.C. in the early writings of Mesopotamia and the Book of Genesis.

Anthrax is a serious disease that is caused by the bacterium Bacillus anthracis. Bacillus anthracis has a very detailed yet simple description. Its shape is given away in its name by bacillus‚ which means rod-shaped and is also arranged in chains. It is gram-positive‚ so it has a simple cell wall. Since B. anthracis is non-motile‚ it is best to use a semi-solid media rather than a wet mount (Bacillus anthracis… [date unkown]). Colonies will resemble the comma-shape because of the bacilli chains and

Anthrax-Bacillus anthracis Anthrax is caused by the bacterium called Bacillus anthracis which is a spore forming‚ rod shaped bacterium. Central spores develop under all growth conditions except the living body of the host. It is classified as Bacilli. The most common form would be the cutaneous form. however as we saw during the 2011‚ terrorist attacks‚ the pulmonary form is very real and a serious threat to life. It affects the lungs and the GI tract. The last form is the
