An opportunistic infection is a serious infection caused by pathogens (bacteria, fungi, parasites or viruses) that under normal conditions, such as in humans with uncompromised immune systems, would cause a mild infection or no infection at all.
A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans.. The human physiological defense against common pathogens (such as Pneumocystis) is mainly the responsibility of the immune system with help by some of the body's normal microbiota.
The opportunistic pathogen can cause hospitalized patients to have infections in the lungs (as pneumonia), blood, urinary tract, and in other body regions after surgery. [6] S. aureus is a Gram-positive, cocci-shaped bacterium, residing in the environment and on the skin and nose of many healthy individuals. [7]
Cryptococcosis is a common opportunistic infection for AIDS and is particularly common among people living with AIDS in Africa. Other conditions that pose an increased risk include certain malignancies (such as lymphoma), liver cirrhosis, organ transplants, and long-term corticosteroid therapy. [20] Distribution is worldwide in soil. [21]
Over time, they cause acquired immunodeficiency syndrome (AIDS), [1] [2] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. [3] Without treatment, the average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. [4]
Opportunistic infection may be caused by microbes ordinarily in contact with the host, such as pathogenic bacteria or fungi in the gastrointestinal or the upper respiratory tract, and they may also result from (otherwise innocuous) microbes acquired from other hosts (as in Clostridioides difficile colitis) or from the environment as a result of ...
Immune reconstitution inflammatory syndrome (IRIS) is a condition seen in some cases of HIV/AIDS or immunosuppression, in which the immune system begins to recover, but then responds to a previously acquired opportunistic infection with an overwhelming inflammatory response that paradoxically makes the symptoms of infection worse.
These opportunistic infections often involve hospital-acquired infections among patients already combating another condition. [ 8 ] Infectivity involves pathogen transmission through direct contact with the bodily fluids or airborne droplets of infected hosts, indirect contact involving contaminated areas/items, or transfer by living vectors ...
