Loiasis a subcutaneous filariasis is caused by Loa loa (the eye worm). Mansonella streptocerca, and Onchocerca volvulus. These worms occupy the layer just under the skin. O. volvulus causes river blindness. Serous cavity filariasis is caused by the worms Mansonella perstans and Mansonella ozzardi, which occupy the serous cavity of the abdomen.
Lymphatic filariasis is a human disease caused by parasitic worms known as filarial worms. [2] [3] Usually acquired in childhood, it is a leading cause of permanent disability worldwide, impacting over a hundred million people and manifesting itself in a variety of severe clinical pathologies [6] [7] While most cases have no symptoms, some people develop a syndrome called elephantiasis, which ...
Loa loa filariasis, (Loiasis) is a skin and eye disease caused by the nematode worm Loa loa.Humans contract this disease through the bite of a deer fly (Chrysops spp.) or mango fly, the vectors for Loa loa.
Brugia timori is a filarial (arthropod-borne) nematode (roundworm) which causes the disease "Timor filariasis", or "Timorian filariasis".While this disease was first described in 1965, [1] the identity of Brugia timori as the causative agent was not known until 1977. [2]
Lymphatic filariasis, also known as elephantiasis, is a condition characterized by swelling of the lower limbs. The two other filarial causes of lymphatic filariasis are Wuchereria bancrofti and Brugia timori, which both differ from B. malayi morphologically, symptomatically, and in geographical extent. [1]
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.
Loa loa causes Loa loa filariasis also known as Calabar swelling; Mansonella streptocerca, which causes streptocerciasis, an itchy condition that creates depigmented skin lesions sometimes mistaken for the first signs of leprosy. Onchocerca volvulus causes cutaneous onchocerciasis and river blindness [7]
Wuchereria bancrofti is a filarial (arthropod-borne) nematode (roundworm) that is the major cause of lymphatic filariasis.It is one of the three parasitic worms, together with Brugia malayi and B. timori, that infect the lymphatic system to cause lymphatic filariasis.
