Tetanus Tetanus is a potentially fatal disease that is rooted throughout all of human history. It is caused by a bacterium that can be contracted in a number of ways. While the human interaction and symptoms are not caused directly by the bacterium affecting human tissue as with normal bacterial infections. Instead, the symptoms common with the infection are caused by a reaction to a neurotoxin called Tetanospasmin (Wells). The symptoms of this toxin on the body are a result of the toxin binding

Chlamydia Chlamydia is one of the most common diseases in the United States. The infection is part of a 'silent epidemic' as most cases do not show symptoms and are left untreated. It can cause pelvic inflammatory disease and lead to scarring of the Fallopian tubes causing infertility and higher risk of ectopic pregnancy. The research was carried out at the Molecular Microbiology Group, at the University of Southampton, in conjunction with the Department of Virology, at the Ben Gurion University

more often than not a disease such as cholera is not a worry because of our clean water supplies and filtration equipment, while in developing third world countries, it is more often the water, and many symptom-less carriers pass large amounts of bacteria in their feces that further contaminate water supplies or transmit by poor hand washing. While Cholera is rarely spread directly from

the properties of individual particles. The Kingdom Monera is the most prominent. Examples of these are the bacteria. Bacteria are the first life forms. They are the smallest and the most numerous. They have no complex organelles and have only a few hundred genes. They grow, replicate DNA and split for every twenty minutes. Another example are the viruses which are much smaller than the bacteria and are not considered as living things. Next, the Kingdom Protista, from the name itself, are composed mainly

very contagious if spread to others or objects are handled by a person who has the hepatitis A virus. The ways to be contaminated by this virus is by someone not washing hands after using the restroom. Or by changing diapers. It is caused by feces bacteria. Also Hepatitis A can be in contaminated water by seafood that we eat. We can also get it from using contaminated needles from either drug use or from hospitals. Very unlikely it would be from hospitals, as in they always use new needles that

The spores possess a though outer covering made of protein keratin which is resistant to staining. 2- Explain the terms sporulation and germination. Sporulation is the process of endospore formation within a vegetative cell; germination is the process of an endospore returning to its vegetative state. 3- List
