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.
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 ...
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
Acute care is a branch of secondary health care where a patient receives active but short-term treatment for a severe injury or episode of illness, an urgent medical condition, or during recovery from surgery. [1] [2] In medical terms, care for acute health conditions is the opposite from chronic care, or longer-term care.
Body substance isolation is a practice of isolating all body substances (blood, urine, feces, tears, etc.) of individuals undergoing medical treatment, particularly emergency medical treatment of those who might be infected with illnesses such as HIV, or hepatitis so as to reduce as much as possible the chances of transmitting these illnesses.

Acute management of diabetic foot infections generally includes antibiotic therapy, pressure offloading, re-vascularization, if appropriate, and debridement of infected tissues (or amputation if necessary). Hospitalization is more likely needed when lower extremity pulses are absent or when infection penetrates to the level of the fascia or ...
Uncomplicated bacteremia is defined as having positive blood cultures for MRSA, but having no evidence of endocarditis, no implanted prostheses, negative blood cultures after 2–4 days of treatment, and signs of clinical improvement after 72 hrs. [44] The antibiotic treatment of choice for streptococcal and enteroccal infections differs by ...
To emphasize both hospital and nonhospital settings, it is sometimes instead called a healthcare-associated infection. [2] Such an infection can be acquired in a hospital, nursing home, rehabilitation facility, outpatient clinic, diagnostic laboratory or other clinical settings. A number of dynamic processes can bring contamination into ...
