A hospital-acquired infection, also known as a nosocomial infection (from the Greek nosokomeion, meaning "hospital"), is an infection that is acquired in a hospital or other healthcare facility. [1] To emphasize both hospital and nonhospital settings, it is sometimes instead called a healthcare-associated infection . [ 2 ]
It is still one of the five most common causes of hospital-acquired infections and is often the cause of wound infections following surgery. Each year, around 500,000 hospital patients in the United States contract a staphylococcal infection, chiefly by S. aureus. [8] Up to 50,000 deaths each year in the U.S. are linked to staphylococcal ...
Hospital acquired pneumonia is the second most common nosocomial infection (after urinary tract infections) and accounts for 15–20% of the total. [ 1 ] [ 2 ] [ 3 ] It is the most common cause of death among nosocomial infections and is the primary cause of death in intensive care units .
However, along with similar bacterial species that can colonize and act symbiotically, they can cause disease if they begin to take over the tissues they have colonized or invade other tissues; the resultant infection has been called a "pathobiont". [2] After 72 hours, MRSA can take hold in human tissues and eventually become resistant to ...
The most common causes of CAP vary depending on a person's age, but they include Streptococcus pneumoniae, viruses, the atypical bacteria, and Haemophilus influenzae. Overall, Streptococcus pneumoniae is the most common cause of community-acquired pneumonia worldwide. Gram-negative bacteria cause CAP in certain at-risk populations. CAP is the ...
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
Mycobacterium tuberculosis is a species of bacteria that causes tuberculosis, a respiratory infection. [13] Pseudomonas aeruginosa is a bacterium that can cause respiratory infections. It is frequently associated with cystic fibrosis and hospital-acquired infections. [14] Salmonella is a genus of bacteria, known to cause gastrointestinal ...
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
