Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. Methicillin-resistant Staphylococcus aureus (MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans.
Other aspects include surveillance, monitoring, and investigating and managing suspected outbreaks of infection within a healthcare setting. [citation needed] A subsidiary aspect of infection control involves preventing the spread of antimicrobial-resistant organisms such as MRSA.
These bacteria pose a great threat to public health due to the limited treatment options available as well as lack of newly developed antimicrobial medications. MDR strains of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii have become of most concern because they have been reported by hospitals all around the United ...
Its role in therapy has been largely replaced by oxacillin (used for clinical antimicrobial susceptibility testing), flucloxacillin and dicloxacillin, but the term methicillin-resistant Staphylococcus aureus (MRSA) continues to be used to describe S. aureus strains resistant to all penicillins.
First-line treatment for serious invasive infections due to MRSA is currently glycopeptide antibiotics (vancomycin and teicoplanin). A number of problems with these antibiotics occur, such as the need for intravenous administration (no oral preparation is available), toxicity, and the need to monitor drug levels regularly by blood tests.
Barrier nursing is a set of stringent infection control techniques used in nursing.The aim of barrier nursing is to protect medical staff against infection by patients and also protect patients with highly infectious diseases from spreading their pathogens to other non-infected people.
Special equipment is used in the management of patients in the various forms of isolation. These most commonly include items of personal protective equipment (gowns, masks, and gloves) and engineering controls (positive pressure rooms, negative pressure rooms, laminar air flow equipment, and various mechanical and structural barriers).

Controlling nosocomial infection is to implement QA/QC measures to the health care sectors, and evidence-based management can be a feasible approach. For those with ventilator-associated or hospital-acquired pneumonia, controlling and monitoring hospital indoor air quality needs to be on agenda in management, [ 21 ] whereas for nosocomial ...
