==Overview==
==[[Opportunistic infection differential diagnosis|Differentiating Opportunistic Infection from other Diseases]]==
'''Opportunistic infections''' are infections caused by organisms that usually do not cause disease in a person with a healthy [[immune system]], but can affect people with a poorly functioning or suppressed [[immune system]]. They need an "opportunity" to infect a person.


==Causes==
==[[Opportunistic infection epidemiology and demographics|Epidemiology and Demographics]]==
[[Immunodeficiency]] or [[immunosuppression]] can be caused by:
* [[Malnutrition]]
* Recurrent [[infection]]s
* Immunosuppressing agents for [[organ transplant]] recipients
* [[Chemotherapy]] for [[cancer]]
* [[AIDS]] or [[HIV]]-infection
* [[genetics|Genetic]] predisposition
* [[Skin]] damage
* [[Antibiotic]] treatment
* Medical procedures


==Types of infections==
==[[Opportunistic infection risk factors|Risk Factors]]==
These infections include:


* [[Pneumocystis pneumonia |''Pneumocystis jirovecii'']], previously known as [[Pneumocystis pneumonia |''Pneumocystis carinii'' f. ''hominis'']]  
==[[Opportunistic infection screening|Screening]]==
* ''[[Candida albicans]]''
 
* ''[[Staphylococcus aureus]]''
==[[Opportunistic infection natural history, complications and prognosis|Natural History, Complications and Prognosis]]==
* ''[[Streptococcus pyogenes]]''
 
* ''[[Pseudomonas aeruginosa]]''
==Diagnosis==
* ''[[Acinetobacter baumanni]]''

==Treatment==
==Treatment==
Treatment depends on the type of opportunistic infection, but usually involves different  [[antibiotic]]s.
