Endospore

known to be mesophiles that live in temperatures ranging from 25 to 35 degree Celsius. According to Microbewiki2 the optimal temperature for B. subtilis growth is 37o C. In addition, B. subtilis live in a harsh environment, however the formation of endospores helps it survive within those…

The mutualistic relationship between fig trees and fig wasps plays an important role for the reproductive fitness of each species. Normally, fig wasps pollenate the fig tree’s compound flowers (syconiums) at the expense of the tree providing a suitable environment for the fig wasps to reproduce in the syconium’s flowers. However, with almost every mutualism there are ‘cheaters’ that will try to take advantage of the benefits without bringing anything to the table. In this case, pollen-free fig…

This paper will discuss two different issues disinfectants and antimicrobial agent susceptibility testing/resistance. To better understand disinfectants we will further explore topics such as: the meaning of bactericidal, bacteriostatic, virucidal, and fungistatic; the importance of using a control culture when evaluating disinfectants; factors that can impact the activity of disinfectants; microorganism having different responses to disinfectants; and identifying the microorganism susceptible…

“Clostridium perfringens is a nonmotile, encapsulated, endospore-forming, gram-positive rod. It is classified as an anaerobe since no colonies arise when agar plates streaked with this bacterium are incubated in the air.” (University of Pittsburgh School of medicine, Par 2) Clostridium perfringens are bacteria that produce toxins harmful to humans. This bacteria are found anywhere in the environment. Basically clostridium perfringens are food poisoning bacteria. Clostridium perfringens is a…

Introduction The existence of Chlamydia trachomatis has only been acknowledged for a little bit over a century. The microorganism was discovered in 1907 by scientists Ludwig Halberstaedter and Stanislaus von Prowazek when they detected it in scrapings of the conjunctiva of an infected orangutan (Budai, 2007). The duo found that similar microbes were found in humans as well. The affected areas were the urethra of males, cervices of women and the eyes of their infants (Dimitrakov, 2002).…

Describe the structure and function of bacteria in comparison to a virus Both bacteria and viruses are mircoogranmisms. Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat called a caspid. They are classed as non-living because they cannot surive on their own. Conversley, bacteria are single celled livng microbes. The cell structure is simpler than that of other organisms as there is no…

Virus Podcast Reflection The thing that surprised me the most about this podcast came at the beginning. I knew that discoveries of bacteria and viruses were fairly recent, with viruses being even more recent because normally they are only a fraction of the size. I didn’t realize that up until 2003, viruses were just lumped into this random category that no one really took the time to sort out and try and make any discoveries in. I think that it makes sense though because researchers want to be…

Molly, an 11 year old female weighing 102 pounds and height 4 feet 9 inches was admitted to Adams Children’s Hospital January 14, 2010. Molly came from Indiana to visit her grandfather Billy in Georgia for summer vacation. Her grandfather was a farmer who produced a variety of foods, he also raised livestock. Billy would most often prepare his sheep’s wool with the help of his granddaughter. Molly enjoyed helping him but, most of all she enjoyed playing with the animals on the farm, she also…

The bacterium is a rod shaped organism which produces endospores, these spores allow the Bacillus to survive in harsh conditions, and this includes heat and desiccation. Although not producing toxins, they can result in food poisoning. Staphylococcus Epidiermudus is a gram positive bacterium which thrives on…

in phone screens or television screens. In the biology field, Tb3+ is used as an indicator for microbes. When the sample is applied with Terbium Chloride, and placed under an ultraviolet light, if there are endospores present, the terbium will make the sample glow a green color. The endospores that are being indicated by the terbium ion are dormant structures created by certain types of bacteria to withstand lack of nutrients. Terbium is also used as a major component is hybrid cars. Because the…
