  Brugia malayi - Wikipedia, the free encyclopedia
Brugia malayi is a filarial worm which causes filariasis in humans.
In 1958 the separate genus Brugia was proposed by Buckley, and Filaria malayi became known as Brugia malayi.
Causal Agents: Filariasis is caused by nematodes (roundworms) that inhabit the lymphatics and subcutaneous tissues.

 Brugi malayi (elephantiasis)   (Site not responding. Last check: 2007-11-03)
Many aspects of the biology of Brugia malayi are similar to Wuchereria bancrofti.
It is a vector borne disease, spread by mosquitos (view diagram of the life cycle), and it can cause elephatiasis.
The primary difference between the two species is that brugian filariasis is not as widely distributed as is bancroftian filariais, although the distributions of the two diseases overlap in many areas of the world (view geographic distribution of filariasis).

Brugia malayi chitinase (BmCHT1) is expressed in the microfilarial stage, the first larval stage, of the organism and is thought to be important in the exsheathment process of the microfilaria (1).
Exsheathment is required for further development of the microfilaria once ingested by the mosquito vector (2).
The microfiliaria of Brugia malayi have been shown to have chitin in their sheaths (3).

Resistance of intact mice to infection with the filarial nematode, Brugia malayi is dependent on the presence of T cells.
In mice, therefore, the prominent Th2-type response elicited by filarial parasites may not be an essential component of the host protective immune response.

The consequence is lymphatic damage and chronic leakage of protein-rich lymph in the tissues, thickening and verrucous changes of the skin, and chronic streptococcal and fungal infections, which all contribute to the appearance of elephantiasis.
B malayi elephantiasis is more likely to affect the upper and lower limbs, with genital pathology and chyluria being rare.
Life cycles of other lymphatic nematodes (ie, Brugia malayi, Brugia timori) are identical, while the life cycles for other filariae differ in the body location of adult worms, the microfilariae present, and the arthropod intermediate hosts and vectors.

Infections with the helminth parasite Brugia malayi share many key features with Th2-mediated allergic diseases, including recruitment of eosinophils.
We have investigated the dynamics of inflammatory cell recruitment under type 2 cytokine conditions in mice infected with B. malayi.
Because B. malayi is known to secrete homologs (Bm macrophage migration inhibitory factor (MIF)-1 and -2) of the human cytokine MIF, we chose to investigate the role this cytokine mimic may play in the development of the novel macrophage phenotype observed during infection.
