of multi drug resistant strain shigella sonnei from its ancestor E. Coli and predecessor S. Flexneri and its spread to Vietnam Introduction Shigella is a genus of Gram-negative, facultative anaerobic, nonspore-forming, nonmotile, rod-shaped bacteria. The genus is named after Kiyoshi Shiga, who first discovered it in 1897. The causative agent of human shigellosis, Shigella causes disease in primates, and is the only naturally found in humans and apes. Shigella is one of the leading bacterial

BIO-L02 Proposition: Reducing the Use of Antibiotics Antibiotics are created using natural substances which bacteria secrete to kill other bacteria when forced to compete for limited nutrients. The first antibiotic, Penicillin, was discovered in the 1928 by Alexander Fleming and began being mass produced by the 1940’s. Within the same decade, resistant strains of bacteria began to appear. (1) Since then, 18 dangerous drug-resistant superbugs have been discovered (according to the CDC).

Antibiotic Resistance Essay Many things were learned while completing this study. I learned that education is one of the keys to reducing the amount of antibiotic resistance. Educating parents who insist on getting antibiotics for every sniffle on the danger of over medicating with antibiotics might help. Educating the general public via infomercials might also help them realize the dangers as well? Doctors need to stand their ground and take back the ground they have lost over the years.

About Antibiotic-Resistant Bacteria Giana Dominguez SCI 214 September 04, 2013 Gloria Young, PhD After reading the information in this assignment and looking at the plot values I honestly still do not understand everything that I read. So I will try to write this summary the best that I possibly can. What I understood from my reading was that antibiotics have been in development over the last eighty years. Antibiotics help fight infections we get from bacteria. Antibiotics come in different

The majority of cases of sepsis are due to bacterial infections, some are due to fungal infections, and very few are due to other causes of infection or agents that may cause SIRS. The infectious agents, usually bacteria, begin infecting almost any organ location or implanted device (for example, skin, lung, gastrointestinal tract, surgical site, intravenous catheter, etc.). The infecting agents or their toxins (or both) then spread directly or indirectly into the bloodstream. This allows them to

It is important to have normal levels of bacteria in our ecosystem. Good levels of bacteria protect the body by preventing other types of bacteria from overgrowing and producing toxins. Good bacteria can also help with breaking down food that the body itself cannot absorb in turn teaching the body to not have an overactive immune system by helping prevent allergies and training immune cells whilst also increase appropriate growth of epithelial cells. It is important to have research and knowledge

Archae and Bacteria Name: Institution: Date: The Archaea is similar to the bacteria in terms of cell structure and size, although possess many distinctive features, including the lack of peptidoglycan in their cell wall, existence of exclusive membrane lipids that are not established in the other domains of life and other distinctive genetic and biochemical properties. Most cultured Archaea were actually recovered from tremendous environments where there are high temperatures, high salt concentration

Factors the affect the rate of decomposition pH of soil The pH of the soil can affect the rate of decomposition as it directly affects the type and activity of the bacteria, fungi and other micro-organisms decomposing material. A highly acidic soil (0-7 pH) or highly alkaline soils (7-14 pH), it is not a ideal environment for the micro-organisms to grow in. It also affects the food the soil biota feeds on, as extreme pH can determine the availability of essential plan nutrients. Temperature
