1. What are prions and satellite viruses? Prions are groups of noncellular infectious agents‚ but are not viruses. In fact‚ they are naked protein molecules that lack nucleic acid. The diseases associated with prions are called Transmissible Spongiform Encephalopathies or TSEs. These diseases spread from host to host through direct contact or through the contamination of food. Satellite viruses are viruses that depend on other viruses to replicate. An example of this is the adeno-associated virus

Rickettsia‚ mycoplasma and chlamydia are three very unique bacterias. Here are a few reasons why for each bacteria. Rickettsia is an obligate intracellular gram-negative bacteria. This type of bacteria is very small and is bacilli shaped. Rickettsia causes rocky mountain spotted fever‚ rickettsia pox‚ epidemic typhus and murine typhus disease. It is found in ticks‚ lice‚ fleas‚ mites‚ chiggers and mammals. It is transmitted by a bite (vector transmission) from an infected tick‚ mite‚ flea or any

Languages When I read the article about languages then it put me thinking. How many languages I can speak myself. And it hit me‚ not much. I can speak Estonian as my native language and English only as my foreign language. It is great that I have French in my university’s studying program because like Louise said in the text- lots of businesses say they want people who can speak European languages‚ but young people do not seem to realize that speaking another language can imrpove their job prospects

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

Haemophilus influenza By Crystal Wade BL 202 A Dr. Kokan 11/10/2012 Haemophilus influenza is a gram negative rod shaped bacterium; it is a member of the pasteurellaceae family. It is aerobic but it can grow as a facultative anaerobe. From 1852 to 1933 H. influenza was thought to be the cause of influenza until its etiology was done and they discovered that it was really bacterial influenza that caused it. H. influenza does cause many other diseases. It states on Wikipedia that “H. influenza

Oxygen concentration: The paradoxical nature can be both toxic and essential to life. Obligate Aerobes rely on aerobic respiration for ATP and they use oxygen as the terminal electron transport chain. Microaerophilic require O2 from growth but they are damaged by normal atmospheric levels of oxygen and don’t have efficient ways to neutralize the toxic forms of oxygen such as superoxide ad hydrogen peroxide. Obligate anaerobes will die in the presence of oxygen because they lack enzymes like superoxide
