According to the University of Pittsburgh Medical Center‚ “Methicillin-Resistant Staphylococcus Aureus has been active within the UPMC hospital system since 2001. UPMC also states that they have reduced the infection rates from 1.1 per 1‚000 patient days in 2001‚ to 0.35 per 1‚000 patient days in 2009‚ while saving millions of dollars a year.” (Elixhauser A‚ Steiner C.‚ July‚ 2007) How has Methicillin-Resistant Staphylococcus Aureus affected the community

Patients with stent‚ develop stent infections and stent-related symptoms. Use of antibiotics in patients with DJ stent is rampant. No uniform data is there to prove advantage of antibiotic prophylaxis. Colonial way of life of microorganisms‚ complex microbial assemblages are responsible for formation of biofilm. Both gram positive and gram negative bacteria produces biofilm. Biofilm is an important virulence factor and is main cause of many chronic infections and multidrug resistant strains resulting

Most P. aeruginosa infections occur in hospitalized patients‚ particularly those who are immunocompromised. P. aeruginosa is a common cause of infections in ICUs. HIV-infected patients‚ particularly those in advanced stages‚ are at risk of community-acquired P. aeruginosa infections. P. aeruginosa infections can develop in many anatomic sites‚ including skin‚ subcutaneous tissue‚ bone‚ ears‚ eyes‚ urinary tract‚ and heart valves. The site varies with the portal of entry and the patient’s vulnerability

Several reports state that enterococcal species possess the property of causing a variety of diseases in humans [3‚ 4]. It is known from previous studies that Enterococcus faecalis can cause endocarditis‚ bacteremia‚ urinary tract infections‚ meningitis and other infections in humans [5‚ 6‚ and 7].
