My research shows the rise in antibiotic resistant pathogens through horizontal gene transfer. Located in the bacteria are plasmids. They are independent‚ self-duplicating‚ and allow bacteria to perform new functions/generate new products. Basically plasmids help their hosts to stop the action of antibiotics and become resistant. “Gene transfer must be integral and critical to the overall survival of bacteria‚ providing a way for them to adapt to difficult conditions” (Levy 2002‚ 83).

Respiratory Case Study The following case study is of a 37-year old Hispanic male weighing 145 lbs and 70 inches tall found unconscious by his girlfriend. According to her he was unconscious for about 15 hours and she was concerned because he would not wake or respond and was breathing shallow and slow. She then called 9-1-1. The patient entered the ER by emergency vehicle and on my initial assessment Pt had an altered mental status‚ was very unresponsive showing symptoms of a possible drug overdose

the distribution of phenotypes. Distribution selection takes place when an extreme phenotype is favored‚ and the distribution curve shifts in that direction. Antibiotic resistant bacteria are an example of directional selection. When an antibiotic is used‚ some bacteria may survive causing it to produce bacteria that is resistant to that antibiotic. Disruptive selection occurs when two or more extreme phenotypes are favored over an intermediate phenotype. An example would be a bird with a large

microorganism becoming resistant? According to Chambers‚ MRSA first began become resistant in the 1940’s has the pathogen began to “ produced a plasmid-encoded penicillinase that hydrolyzes the beta-lactam ring of penicillin” which is responsible for the antimicrobial actions of penicillin. Methicillin kept the microorganism in check for a while but the stains soon overcame it as well. What current treatments are available? Although MRSA is resistant to some drugs‚ it is not resistant to others. It

MULTIDRUG-RESISTANT TUBERCULOSIS IN THE UNITED STATES: WHAT IT IS‚ CHALLENGES FOR PUBLIC HEALTH OFFICIALS‚ HOW TO PREVENT IT 24 July 2009 Abstract Hippocrates once described a common illness as “phthisis‚” which today is believed to have been the same disease we now call tuberculosis‚ or TB. Many centuries have passed since Hippocrates‚ and TB has been a major scourge to humans as well as other species. In the early 20th Century‚ TB was called

I will be looking at and comparing factors such as how the diet effects their energy levels‚ mental focus‚ hunger levels‚ heart rate‚ the rate of weight-loss and tiredness. Hypothesis: According to research done by Prof Tim Noakes (2013)‚ the Banting diet should be most effective on people who are insulin-resistant‚ because

Scientists have now isolated bacteria from batches of eggs known to cause the illness‚ and they found that the bacteria are resistant to kanamycin. The contaminated eggs were found to have come from three different chicken farms‚ Acme‚ Big AL’s‚ and Clucky’s chicken farm‚ that are geographically separate‚ and are in different states. The scientists also know that there are three

These organisms are resistant to high temperatures (as high as 50°C)‚ high salt concentrations and drying (Tolan‚ 2011). It is a common microorganism and can usually be found in the human axilla‚ inguinal area or nose. There are a lot of antibiotics that are used to treat staphylococcal infections. They have been found to be most responsive to a group of antibiotics called beta-lactams that include oxacillin‚
