Mansonella perstans

Man·son·el·la per·'stans

the "persistent filaria," a species widely prevalent in tropic Africa and northern South America where it infects human peritoneal and other body cavities, but is nonpathogenic or only mildly so; characteristic subperiodic microfilariae occur in peripheral blood. It is transmitted in Africa by the biting midges Culicoides austeni and C. grahami.

Mansonella perstans

A filarial nematode which causes serosal filariasis in humans.

Epidemiology
Subsaharan Africa, Central and South America, Caribbean.

Vector
Haematophagous midges (genus Culicoides).

Clinical findings
Generally banal, with moderate fever, articular pain, headache, pruritis, rash, pulmonary symptoms, lymphadenopathy and hepatomegaly.
 
Management
Ivermectin is effective against microfilariae, but not against adult worms.

Mansonella perstans

A species of filaria that is transmitted to humans by Culicoides insects (midges). It was formerly known at Acanthocheilonema perstans.

Symptoms

Angioedema, urticaria, high blood eosinophil levels, and other findings.
