Serous cavity filariasis is caused by the worms Mansonella perstans and Mansonella ozzardi, which occupy the serous cavity of the abdomen. Dirofilaria immitis, the dog heartworm, rarely infects humans. Filariasis is caused by parasitic nematodes. These worms are transmitted by infected mosquitoes of the genera Aedes, Culex, Anopheles and Mansonia.

Diethylcarbamazine is a medication used in the treatment of filariasis including lymphatic filariasis, tropical pulmonary eosinophilia, and loiasis. [1] It may also be used for prevention of loiasis in those at high risk. [1] While it has been used for onchocerciasis (river blindness), ivermectin is preferred. [2] It is taken by mouth. [3]
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.
The prevention and treatment plans differ according to whatever is effective against the species in a given region. [2] The creation of maps and planning of local monitoring systems has been an essential part of all regional eradication plans. [3]
Mansonella perstans is a filarial (arthropod-borne) nematode (roundworm), transmitted by tiny blood-sucking flies called midges. [1] Mansonella perstans is one of two filarial nematodes that causes serous cavity filariasis in humans.
Ivermectin is an antiparasitic drug. [7] After its discovery in 1975, [8] its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. [9] Approved for human use in 1987, [10] it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis.
