Sarah Burns Evolution of Plague Bacteria The Bubonic Plague otherwise known as the Black Death‚ has gotten most of its attention from medieval paintings‚ poetry‚ and journals of revulsion. The real horror‚ was the disturbing biological evidence of the bacteria that caused all the pandemics‚ known as Yersinia pestis. The pathogen got its name from the two investigators Yersin and Kitasato. In 1894‚ Yersin was known as the main investigator (ergo. Named after him)‚ he claimed that the mice/rats were

Biofilters November 2011 B iofilters are a proven and effective method for reducing odor and other gaseous emissions from mechanically ventilated animal facilities and manure storage units. Biofilters work by absorbing noxious gases into a biofilm where microorganisms break down the gases into carbon dioxide‚ water‚ and salts and use the energy and nutrients to grow and reproduce. Well-designed and managed biofilters can reduce odors and hydrogen sulfide (H2S) by as much as 95 percent and

The cinnamon oil has antimicrobial action in the range 10-150 μg ml − 1. Another intriguing fact about cinnamon is its role in altering or changing the expression of a gene icaA which plays a role in the formation of biofilms. Staphylococcus epidermidis is one of the causes of biofilms which is why it has emerged as a notorious nosocomial pathogens. The literature on the effect of cinnamon on viruses is definite and limited. However‚ it is said to prohibit protein synthesis which is responsible for

cooperation of evolutionary biology with modern medicine has helped with understanding antibiotic resistance and susceptibility‚ spread of disease‚ and development of cancer. I will be discussing the antibiotic resistance and susceptibility of E. Coli Biofilms‚ the spread of Tuberculosis‚ and the changes in breast cancer cell DNA. These different examples are going to prove how evolution has affected medicine and illnesses within modern medicine. In 2013‚ a study on bacterial E. Coli was performed‚ by

Micheli. Gingivitis-Gingivitis ("inflammation of the gum tissue") is a non-destructive disease that occurs around the teeth.The most common form of gingivitis‚ and the most common form of periodontal disease overall‚ is in response to bacterial biofilms (also called plaque) that is attached to tooth surfaces‚ termed plaque-induced gingivitis.

it detaches the tooth from the gingiva. Other bacterium associated with periodontal disease include: Campylobacter‚ Peptostreptococcus‚ Porphyromonas gingivalis‚ and Tannerella forsythensis. These pathogens spread and produce cytokines and form a biofilm on the surface of the teeth. All of these bacteria can only be seen through a microscope. Treatment of periodontal disease can be done at home. Brushing twice a day‚ flossing‚ and using mouthwash or toothpaste that contains fluoride can all be preventative
