many people have some living on their skin all of the time and it can cause infection anywhere in the body. There are antibiotics that have been known to kill this bacterium. Unfortunately‚ there is a new form of staph infection called community associated methicillin resistant staphylococcus Aureus (CA-MRSA). This infection is a rising concern because there is no antibiotic that has been known to cure it. CA-MRSA is found on the

interacting with microbial functions or structures different from those of the host; thereby showing little or no effect to the host. 2. What are broad and narrow spectrum antimicrobials? What are the pros and cons of each? Broad spectrum antibiotics work against many types of organisms such as gram positives‚ gram negatives and anaerobes. The great thing about this is that these are prescribed empirically so that all potential bacteria are covered until the culture results return. The problem

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).

A pathogen is a tiny non-visible disease causing microorganism such as Bacteria‚ Virus and Fungus. Both the scientific name and common name for Actinomycosis is Actinomycosis. The pathogens that cause Actinomycosis are from a species of Actinomyces‚ most commonly known as Actinomyces Israelii and Actinomyces Gerencseriae. The species of Actinomyces are an Actinobacteria class of Bacteria. The pathogens are endogenous‚ meaning the bacteria originate from inside the body‚ making them not liable to

Dramatic increase in antibiotic resistance is an after effect of genetic material transfer from species to species and within species. Egression of Strains like VREF (vancomycin resistant Enterococcus faecalis)‚ MRSA (Methicillin resistant staphylococcus aureus) add complexity to current drug resistance problems. Use of broad spectrum antibiotics as medicational strategies transforms them from its normal state as gut commensal to leading

the bloodstream‚ surgical wounds‚ lungs and heart valves. Both health care-associated and community-associated strains of MRSA still respond to certain antibiotics. Doctors usually drain the superficial abscesses caused by MRSA and then treat the infection with drugs. The majority of serious MRSA infections are treated with two or more antibiotics that in combination are often still effective against MRSA. Some examples of some of the drugs used would be Vancomycin‚ Bactrim‚ Zyvox‚ Septra‚ and Rifadin

dependency on antibiotics‚ E. Faecalis is becoming feared due to its intrinsic antibiotic resistance (Wesley Glick‚ 2000). This strain is naturally immune to weaker levels of penicillin because of its ability to synthesize cell wall components in the presence of penicillin. Instead of allowing this antibiotic to destroy the cell wall‚ E. Faecalis produces penicillin-binding proteins that inhibit penicillin from disintegrating its cell wall (Susan L. Fraser‚ 2012). Thus a more effective antibiotic must
