What is the difference between W bancrofti and B. malayi microfilariae?
bancrofti are more protruding while in B. malayi they are flattened. The lateral caudal papillae in B. malayi have an indentation around their bases which is absent in W.
Where is Brugia malayi found in the body?
The typical vector for Brugia malayi filariasis are mosquito species from the genera Mansonia and Aedes. During a blood meal, an infected mosquito introduces third-stage filarial larvae onto the skin of the human host, where they penetrate into the bite wound .
What disease is caused by Wuchereria bancrofti?
There are three different filarial species that can cause lymphatic filariasis in humans. Most of the infections worldwide are caused by Wuchereria bancrofti. In Asia, the disease can also be caused by Brugia malayi and Brugia timori.
What is the common name of Wuchereria bancrofti?
timori, that infect the lymphatic system to cause lymphatic filariasis. These filarial worms are spread by a variety of mosquito vector species….Parasite.

What are the characteristics of Brugia malayi?
Long and threadlike, B. malayi and other nematode possess only longitudinal muscles and move in an S-shape motion. Adults are typically smaller than adult W. bancrofti, though few adults have been isolated. Female adult worms (50 mm) are larger than male worms (25 mm).
What disease does Brugia malayi cause?
Brugia malayi is a filarial (arthropod-borne) nematode (roundworm), one of the three causative agents of lymphatic filariasis in humans. Lymphatic filariasis, also known as elephantiasis, is a condition characterized by swelling of the lower limbs.
What are the symptoms of Brugia malayi?
Transmission is by mosquitoes that ingest the microfilariae and inject larvae when they bite humans. Of the patients who have tropical eosinophilia, 80% are men, and the lungs are involved in more than 90% of cases. Clinical manifestations include fever, weakness, anorexia, weight loss, cough, wheezing, and dyspnea.
What does filariasis look like?
Symptoms may include itchy skin (pruritis), abdominal pain, chest pain, muscle pain (myalgias), and/or areas of swelling under the skin. Other symptoms may include an abnormally enlarged liver and spleen (hepatosplenomegaly), and inflammation in the affected organs.
Where is Wuchereria bancrofti found?
lymph nodes
Wuchereria bancrofti is a filarial worm found in the lymph nodes of humans causing a lymphatic filariasis called Bancroft’s filariasis.
Is filariasis and elephantiasis same?
Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection occurs when filarial parasites are transmitted to humans through mosquitoes. Infection is usually acquired in childhood causing hidden damage to the lymphatic system.
What worm causes elephantiasis?
Filarial nematodes cause several chronic human diseases, including elephantiasis and river blindness.
