Infectious Disease Tamarra Burnett HCA/240 5/11/2014 Bruce Gould Infectious Disease Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that is resistant to most antibiotics. MRSA is also referred to as the superbug or the flesh eating disease. It is common for patients to contract MRSA in hospital and nursing home facilities. In these particular settings‚ it is often life threatening. The University of Chicago Medicine reports more than 90‚000 Americans suffer

white phenotypes. Many pathogenic bacteria species are becoming resistant to antibiotics. Explain how such adaptations can develop through the process of natural selection. (Hint: Relate this example to the conditions that are necessary for natural selection to occur.) Antibiotic resistance is the ability of a microorganism to withstand the effects of an antibiotic. It is a specific type of drug resistance. Antibiotic resistance evolves naturally via natural selection through random mutation‚ but

IS GENETICALLY MODIFIED FOODS REALLY SAFE AS WE THINK ? Since the beginning of life‚ nourishment is the first requirement for all kind of alive. According to Chassy (2007)‚ early humans lived a hunter gatherer lifestyle and that around 10000 years ago they started to transition into an agricultural lifestyle. Also they feed animals to their milk‚ meat and eggs. Later‚ some people interested in agriculture in order to survive and earn money. In today’s world‚ technological developments

Poop Pills Article Every year millions of Americans get an infection in the stomach called Clostridium difficile (aka C-diff). There are antibiotics that can cure it but in the past they haven’t worked as well as expected. They kill off the infection but in the process it destroys good bacteria too. This can cause another infection in the future because your body isn’t powerful enough to prevent it. There are other cures to C-diff too‚ like fecal transplants. This is the process where stool from

According to Mary Bellis from “The History of Penicillin‚” “Penicillin is one of the earliest discovered and widely used antibiotic agents‚ derived from the Penicillium mold” (123). Penicillin is a vital part of today’s society and is considered a major drug in modern society. This drug has risen to be an important drug because of its discovery‚ and the development of the antibiotic. Penicillin could not cure so many people if it was never discovered. Accidents are a major factor of how many discoveries

Enterococcus By Richard Guilford Enterococcus Enterococcus‚ or more appropriately enterococci‚ are a family of bacteria in the division firmicutes (meaning strong skin and referring to the cell wall) and the class bacilli (which refers to its rod like shape). They look just like streptococcus bacteria from physical characteristics alone. In fact‚ members of the genus Enterococcus were classified as Group D Streptococcus until 1984 when genomic DNA analysis showed that a separate genus classification
Premium Antibiotic resistance Bacteria
Bacteria become resistant with mutations and by swapping DNA with a bacteria that is already resistant. The resistance of bacteria to antibiotics is a textbook example of evolution. The mutant bacteria will survive due to natural selection and will continue to cause illness in the patient. One thing that can be done to stop this evolution of bacteria is to somehow replace the bacteria’s DNA/RNA
