Characteristics of MRSA Staphylococcus aureus is a group of lactic acid-producing bacteria commonly found on the surface of the skin. When it penetrates a break in the surface‚ it induces an immune response that involves hydrogen peroxide and nitric oxide. For example‚ when it reaches the gut‚ it induces what is clinically referred to as enterocolitis‚ or infection of the digestive tract (Suzuki‚ 1994). Methicillin-resistant S. aureus (MRSA)‚ just like other S. aureus strains avoids such immune

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

Methicillin-resistant Staphylococcus aureus (MRSA) is more common than most people think. According to Centers for Disease Control and Prevention (CDC) (2013) Workplace Safety & Health Topics. MRSA and the Workplace: Staphylococcus aureus (S. aureus)‚ also known as staph‚ is a type of bacteria that most healthy people carry on their skin‚ or in their nose. The MRSA refers to the staph

Multiplication of contaminant bacteria in urine and interpretation of delayed culture. Abstract A prospective study of the bacterial populations of non-infected urine was mounted in an attempt to define the length of delay between voiding and analysis during which culture would not give false positive results due to the multiplication of contaminant bacteria present at the time of voiding. The findings suggest that culture of urine within four hours of voiding is likely to give a true indication

organisms. There are two main theories of evolution the correct of the two is Darwin’s theory of Natural Selection. Evolution can be proven through embryos‚ fossils‚ anti-biotic resistant bacteria and much more. Darwin’s theory also applies to St. Aureus as an overuse of antibiotics accelerated the evolution leading to the development of MRSA. MRSA is a type of bacteria resistant to antibiotics containing penicillin. MRSA is also known to be a super bug where it thrives in
