Frequently clinicians report adult cases of patients with opportunistic infections as disseminated tuberculosis and/or fungal infections in patients consider as immunocompetent based mainly in the absence of human immunodeficiency virus infection (HIV negative).
Opportunistic infections (OIs) are defined as infections that are more frequent or more severe because of immune suppression in HIV-infected patients, and they are the major clinical manifestation of HIV patients.
Patients living with HIV-AIDS suffer from many opportunistic infections during their disease span like pulmonary and extra pulmonary tuberculosis by typical and atypical mycobacteria, gastrointestinal infections especially by cryptosporiodiosis, fungal infections especially candidiasis, viral infections especially cytomegalovirus, various pnuemonias most importantly by pneumocystic carinii, and many more.
Generally, opportunistic infections result from at least 1 of 3 mechanisms: (1) external acquisition of a virulent pathogen (e.g., meningococcal meningitis or pneumococcal pneumonia), (2) reactivation of an internal latent organism (e.g., herpes simplex virus, herpes zoster virus [shingles], or TB, and (3) invasion of a normally commensal organism (e.g., bacteria, viruses, fungi, or protozoa/ parasites).
