'''Infeksi oportunistik''' adalah [[infeksi]] yang disebabkan oleh organisme (seperti bakteri, jamur, parasit, atau virus) yang memanfaatkan kesempatan yang biasanya tidak tersedia.

== Penyebab ==
[[Imunodefisiensi]] atau [[imunosupresi]] ditandai dengan tidak adanya atau gangguan pada komponen sistem imun, yang menyebabkan turunnya fungsi imun secara umum imunitas terhadap patogen. Kedua kondisi ini dapat disebabkan oleh berbagai faktor, termasuk:
* [[Malnutrisi]]
* [[Kelelahan]]
* Infeksi berulang atau kambuh
* Pemberian [[obat imunosupresif]] bagi penerima [[transplantasi organ]]
* Pemberian [[kemoterapi]] untuk [[kanker]]
▲* [[AIDS]] atau infeksi [[HIV]]
▲* Kerusakan [[kulit]]
* Pemberian [[antibiotik]] yang selanjutnya mengganggu keseimbangan [[mikrobioma]] dan memungkinkan beberapa [[mikroorganisme]] mengalahkan mikroorganisme yang lain dan menjadi patogen (misalnya gangguan [[mikrobiota usus]] dapat menyebabkan infeksi ''Clostridium difficile'')
* Kehamilan
* Penuaan
* [[Leukopenia]] (misalnya [[neutropenia]] dan [[limfositopenia]])
* [[Luka bakar]]
* Gangguan atau ketidakseimbangan mikrobiota vagina yang kemudian memungkinkan proliferasi mikroorganisme oportunistik dan menyebabkan [[vaginosis bakterialis]].<ref name="AfricaNel2014">{{cite journal|date=July 2014|title=Anaerobes and bacterial vaginosis in pregnancy: virulence factors contributing to vaginal colonisation|journal=International Journal of Environmental Research and Public Health|volume=11|issue=7|pages=6979–7000|doi=10.3390/ijerph110706979|pmc=4113856|pmid=25014248|vauthors=Africa CW, Nel J, Stemmet M|doi-access=free}}</ref><ref name="Mastro2013">{{cite journal|date=July 2013|title=Bacterial vaginosis: a review on clinical trials with probiotics|url=http://www.newmicrobiologica.org/PUB/allegati_pdf/2013/3/229.pdf|journal=The New Microbiologica|volume=36|issue=3|pages=229–38|pmid=23912864|vauthors=Mastromarino P, Vitali B, Mosca L}}</ref><ref>{{cite journal|date=July 2013|title=Bacterial vaginosis: a review on clinical trials with probiotics|url=http://www.newmicrobiologica.org/PUB/allegati_pdf/2013/3/229.pdf|journal=The New Microbiologica|volume=36|issue=3|pages=229–38|pmid=23912864|vauthors=Mastromarino P, Vitali B, Mosca L}}</ref><ref>{{cite journal|date=April 2011|title=First report of Atopobium vaginae bacteremia with fetal loss after chorionic villus sampling|journal=Journal of Clinical Microbiology|volume=49|issue=4|pages=1684–6|doi=10.1128/JCM.01655-10|pmc=3122803|pmid=21289141|vauthors=Knoester M, Lashley LE, Wessels E, Oepkes D, Kuijper EJ}}</ref>
