- Nosocomial infections are infections are acquired in hospitals and other healthcare facilities. To be classified as a nosocomial infection, the patient must have been admitted for reasons other than the infection. He or she must also have shown no signs of active or incubating infection. These infections occur:

opportunistic infection opportunistic infection. n. An infection by a microorganism that normally does not cause disease but becomes pathogenic when the body's immune system is impaired and unable to fight off infection, as in AIDS and certain other diseases.pportunistic infection, n an infection by a microbial organism to which the patient is usually resistant; however, because of reduced vitality or through suppression of the immune system, the patient has become infected.

- Enterococci can also cause urinary tract infections; intraabdominal, pelvic, and wound infections; superinfections (particularly in patients receiving expanded-spectrum cephalosporins); and bacteremias (often together with other organisms). They are now the third most common organism seen in nosocomial infections.

- It is responsible for 5 to 35% of all NI and for approximately 90% of all outbreaks of diseases in an ICU(2-3,6-7). The ICU high mortality rates, commonly ranging from 9 to 38%, can reach 60% due to nosocomial infection occurrence(5,8).

- 5.1 Risk stratification (1) Acquisition of nosocomial infection is determinedby both patient factors, such as degree of immuno-compromise, and interventions performed whichincrease risk. The level of patient care practice maydiffer for patient groups at different risk of acquistionof infection.

Nosocomial Infections: Definition, Causes & Prevention So, when you go to the hospital, you might get sick precisely because of that. A hospital-acquired infection is more technically known as a nosocomial infection. There's more than one reason why someone may get an infection or disease they never had prior to entering the hospital.

Pseudomonas rarely causes infection in healthy individuals but it is a major cause of hospital acquired (nosocomial) infections.seudomonas aeruginosa: The versatile blue-green pus bacteria that opportunistically infects people, especially those who are immunocompromised.

Cryptococcosis Cryptococcosis is a systemic fungal disease that may affect the respiratory tract (especially the nasal cavity), CNS, eyes, and skin (particularly of the face and neck of cats). The causal fungi, Cryptococcus neoformans and C gattii, exist in the environment and in tissues in a yeast form. Infection occurs worldwide.

Cryptococcosis Not to be confused with Cryptosporidiosis. Cryptococcosis, also known as cryptococcal disease, is a potentially fatal fungal disease. It is caused by one of two species; Cryptococcus neoformans and Cryptococcus gattii. These were all previously thought to be subspecies of C. neoformans but have now been identified as distinct species.

Nosocomial Infections & Hospital-Acquired Illnesses - Overview According to the CDC, the most common pathogens that cause nosocomial infections are Staphylococcus aureus, Pseudomonas aeruginosa, and E. coli. Some of the common nosocomial infections are urinary tract infections, respiratory pneumonia, surgical site wound infections, bacteremia, gastrointestinal and skin infections.he most common type of nosocomial infections are surgical wound infections, respiratory infections, genitourinary infections, as well as gastrointestinal infections.

Nosocomial Infection Update Historically, staphylococci, pseudomonads, and Escherichia coli have been the nosocomial infection troika; nosocomial pneumonia, surgical wound infections, and vascular accessrelated bacteremia have caused the most illness and death in hospitalized patients; and intensive care units have been the epicenters of antibiotic resistance.

- Hospital-acquired infections are a common, costly, and potentially lethal patient safety problem [ 1, 2 ]. The most common hospital-acquired infection is urinary tract infection (UTI), which accounts for almost 40% of all nosocomial infections [ 3 – 5 ].

Safe Care These infections number approximately 500,000 per year, among an estimated 27 million surgical procedures and account for approximately one quarter of the estimated 2 million nosocomial infections in the United States each year. Infections result in longer hospitalization and higher costs.

Warning: Whether programs or services other than those for infection control are offered will depend on whether the hospital's personnel health service is devoted mainly to controlling infectious diseases or to providing a comprehensive health program for personnel.iral respiratory infections are common problems for infection control programs. The role of viruses in nosocomial infections has been recently discussed (60-62) (also, see Guideline for Prevention of Nosocomial Pneumonia). Hospital personnel, visitors, and patients are important sources of viruses.

Stenotrophomonas maltophilia Stenotrophomonas maltophilia: A bacteria that is usually found in aquatic environments, is not very virulent and rarely infects humans. Most cases of infection tends to occur through use of hospital appliances such as catheters, I.V lines and breathing tubes in immunocompromised people. species of STENOTROPHOMONAS, formerly called Xanthomonas maltophilia, which reduces nitrate. It is a cause of hospital-acquired ocular and lung infections, especially in those patients with cystic fibrosis and those who are immunosuppressed.

Urinary tract infections are the most common type of nosocomial infection. In the United States, surgical site infections, bloodstream infections, and pneumonia are the other most common types (WHO, 2012).

Acute and Chronic Bacterial Cystitis Urinary tract infections (UTIs) are the most common nosocomial infections. They account for more than 7 million physician visits and over 1 million hospital admissions in the United States each year. They are the most common bacterial infection in older adults and the most frequent source of bacteremia.

Ophthalmia Neonatorum Synonym: conjunctivitis of the newborn, neonatal conjunctivitis. Ophthalmia neonatorum refers to any conjunctivitis occurring in the first 28 days of life. It is most commonly infective in origin: bacterial causes include Chlamydia trachomatis, Neisseria gonorrhoeae, Staphylococcus aureus, Streptococcus pneumoniae and various other organisms.

Enterococcus Enterococci are the leading cause of nosocomial infection (or secondary infection aquired while in a hospital). They are responsible for approximately 110,000 cases of urinary tract infection, 25,000 cases of bacteremia, 40,000 wound infections, and 1,100 cases of endocarditis yearly in the United States.
