Microsporidiosis is an opportunistic intestinal infection that causes diarrhea and wasting in ... Although it is classified as a protozoal disease in ICD-10, ...
Since opportunistic infections can cause severe disease, much emphasis is placed on measures to prevent infection. Such a strategy usually includes restoration of the immune system as soon as possible, avoiding exposures to infectious agents, and using antimicrobial medications ("prophylactic medications") directed against specific infections.
Acinetobacter baumannii is a typically short, almost round, rod-shaped (coccobacillus) Gram-negative bacterium.It is named after the bacteriologist Paul Baumann. [2] It can be an opportunistic pathogen in humans, affecting people with compromised immune systems, and is becoming increasingly important as a hospital-derived infection.
Adult-onset immunodeficiency syndrome is a type of immunodeficiency.It is linked to vulnerability to disseminated infections brought on by opportunistic pathogens.People with this condition have increased levels of anti-interferon-gamma autoantibodies.
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]
Pneumocystis infection can also be diagnosed by immunofluorescent or histochemical staining of the specimen, and more recently by molecular analysis of polymerase chain reaction products comparing DNA samples. Notably, simple molecular detection of P. jirovecii in lung fluids does not mean that a person has PCP or infection by HIV.
There may be no symptoms, [4] or talaromycosis may present with small painless skin lesions. [2] The head and neck are most often affected. [2] Other features include: fever, general discomfort, weight loss, cough, difficulty breathing, diarrhoea, abdominal pain, swelling of the spleen (splenomegaly), liver swelling (hepatomegaly), swollen lymph nodes (lymphadenopathy), [2] and anemia.
Mycobacterium avium-intracellulare infection (MAI) is an atypical mycobacterial infection, i.e. one with nontuberculous mycobacteria or NTM, caused by Mycobacterium avium complex (MAC), which is made of two Mycobacterium species, M. avium and M. intracellulare. [1]
