Biological Evolution Of MRSA
Methicillin Resistant Staphylococcus Aureus
Methicillin Resistant Staphylococcus Aureus (MRSA) is a bacteria resistant to all antibiotics containing penicillin. MRSA otherwise known as a superbug has been produced through the process of natural selection inside hospitals, which provide the perfect environment for this bacteria to thrive in. Bacteria like MRSA are hard to treat as there are fewer antibiotics to treat it therefore increasing its deadliness. The antimicrobial resistance in MRSA is genetically based, meaning that it can spread its immunity amongst other bacteria by horizontal gene transfer. MRSA is a bacteria that can withstand antibiotics containing penicillins.

Methicillin was originally introduced in 1959 to combat infections that were caused by PRSA otherwise known as Penicillin Resistant Staphylococcus Aureus. During 1961 it was discovered in the United Kingdom that Staphylococcus Aureus had mutated to become resistant to methicillin. This bacteria was now called MRSA (Methicillin Resistant Staphylococcus Aureus). MRSA was soon known to have spread or developed in other countries such as Japan, Australia, United States and some countries within mainland Europe. MRSA today has spread into many countries and becoming more infectious within hospitals, which as previously mentioned, are perfect breeding grounds for …show more content…
For a bacteria to evolve in this case to become resistant to methicillin, there must be a large population of the bacteria. In a large population of bacteria there will be different types of genes which have different traits. In a sustained environment the genes within the bacteria are quite diverse and different, making evolution quite a lengthy process. This all changes when an environmental pressure comes into effect. In this case antibiotics were used to kill off the bacteria. Almost all the bacteria die except for the ones that have previously mutated to include resistance against this certain antibiotic. Having all bacteria vulnerable to the antibiotic destroyed, means only the resistant bacteria are able to reproduce, so as a result their offspring inheriting the same genetic resistance. Over a lengthened period almost all of the bacteria within the environment become
Hunting Nightmare Bacteria Case Study
986 Words | 4 PagesHunting nightmare bacteria Answer the following questions Case of Addy (the girl from Arizona ) 1- Based on the pediatrician observations what was Addy’s diagnosis at the Pediatric Hospital intensive care unit ? She had got infected by staff or positive bacteria called Methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a community associated bacteria that infects kids when they are playing in playing ground and getting scabs on their knee. They spread through that wound and it has very high resistance to antibiotics.

Antibiotics work great against bacteria, however they don’t work against viruses. Penicillin was the first antibiotic to be discovered by Alexander Fleming, and it was first used to treat infections. Essentially, these powerful medicines fight bacterial infections, and have the potential to save lives.
Staphylococcus Aureus Research Paper
1646 Words | 7 PagesMulti Resistant Staphylococcus aureus (MRSA) is a strand of Staphylococcus aureus that has become resistant to many commonly used antibiotics. Staphylococcus aureus is an infectious disease that is mostly harmless. However, upon entering the body, it can cause various types of infections in almost any part or organ system within the body. These infections include skin infections, invasive infections, and in rare cases it may cause illness.

This is why penicillin was such a good thing. Now soldiers didn’t have to worry as much if they got wounded in battle.

1918-1939 Was A Period Of Progress In Canada
996 Words | 4 PagesMoreover, Penicillin, a group of antibiotics, was discovered during this time, specifically in the 1928s by Alexander Fleming (ACS, 2023). Although the first dose of penicillin was used in 1941 by Albert Alexander, it was still a life-changing discovery as it changed the lives of many - even after the period of 1918s1939s (Wood, 2010). The discovery of penicillin allowed a lot of life-threatening diseases to be treated, such as bronchitis, tonsillitis, and pneumonia. Penicillin is known to save millions of lives. Indeed, in just World War Two, the death rate because of bacterial pneumonia would go from 18% to 1%, because of the invention of penicillin.

Theresa Drew, mother of Ricky Lannetti, tells the story of her son’s fatal experience. Ricky Lannetti was a strong and athletic twenty-one year old. Ricky had contracted Methicillin-resistant Staphylococcus aureus (MRSA), or better known as the “superbug”. He had reported having common flu-like symptoms leading up to the climax of this infection.

624 Words | 3 PagesINTRODUCTION: In this experiment I was testing for antimicrobial sensitivity of Staphylococcus epidermidis by using the Kirby-Bauer Diffusion test. The three antibiotics utilized in this lab were: gentamicin, novobiocin, and penicillin. I determined the effectiveness of the antibiotic by observing and measuring the zone of inhibition for each antibiotic.

Another example of biodiversity evolution is genetic biodiversity. Genetic biodiversity is the variation of the genes that exist within a specific species. Maintaining a genetic diversity gives the population protection against change, which allows it to evolve and adapt to a new environment.
Natural Selection Vs Creationism
1372 Words | 6 PagesIntroduction Evolution is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.(By Ker Than, Live Science Contributor). Charles Darwin’s idea about evolution says that it happens by natural selection. Natural selection is a system of when populations adapt and evolve. (American Museum of Natural History).

Diseases can be taken form in human body and warm-blooded animals such as septicemia and endocarditis. In fact, S. Epidermidis is not too harmful on healthy tissue. The infection often occurs on newborn baby, drug users, and older people and those who need to use assistant devices on every part
Shigellosis Case Study
770 Words | 4 Pages2.2.6 Antibiotic resistance Wide spread resistance to first line of antimicrobials has complicated the selection of drugs for the treatment of shigellosis. Sulphonamides were first introduced in the early 1940s and all Shigella strains were sensitive to this drug. In 1940s, tetracycline followed by chloramphenicol, were recommended for the treatment of shigellosis because sulphonamides became ineffective. Soon, resistance to these two drugs was observed and ampicillin and co-trimoxazole came to the rescue and were found to be clinically highly effective (Ross et al., 1972; Nelson et al., 1976).
