Author summary Brugia malayi is a parasitic nematode and one of the causative agents of lymphatic filariasis, a disease that affects 70 million people worldwide. Currently, there are no effective therapeutics that kill adult filarial parasites when given as a short course. This limitation has hampered global eradication efforts. Studies have shown that the intestinal tract in . Inside the body, adult filarial worms can migrate and form lumps in the lymph vessels or under the skin, depending on type of filarial worm causing infection. Adult female worms produce immature forms of the worm called microfilariae.
Filariasis is major public health hazard particularly in tropical countries like India. The presence of microfilaria using fine needle aspiration cytology has been reported from various sites. However, the presence of the adult gravid filarial worm with a surrounding host response has rarely been reported on breast aspirates. The action of DEC on adult filarial worms is species dependent. The drug shows only poor or no activity on the macrofilariae of bustyp.xyzi and D. viteae. in rodents and Dirofilaria immitis and bustyp.xyz in dogs. The adult worms of O. volvulus are also not susceptible to DEC.
These adult worms live and mate encased in fibrous nodules just below the skin surface and can live there for up to years. It has been discovered that a type of Rickettsia (Wolbachia spp.) has a symbiotic relationship with filarial nematodes. The bacteria initiates the filarial disease process with a severe adverse inflammatory reaction. Threadlike adult filarial worms reside in lymphatic or subcutaneous tissues. Gravid females produce live offspring (microfilariae) that circulate in blood or migrate through tissues. When ingested by a suitable bloodsucking insect (mosquitoes or flies), microfilariae develop into infective larvae.
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 bustyp.xyz two other filarial causes of lymphatic filariasis are Wuchereria bancrofti and Brugia timori, which both differ from B. malayi . Author summary Lymphatic filariasis (LF) is endemic in 72 countries of Africa, Asia, Oceania, and the Americas. It causes painful, disabling hydrocele in an estimated 25 million men. Hydrocele leads to reduced mobility, social exclusion, and depression, all of which limit the men’s ability to work. Filarial hydrocele can be corrected with surgery with few complications.
Adult filarial worms: long and thin - found in tissues, tissue spaces, body cavities, vasculature, and lymphatics of vertebrates except _____ - no ___ or cuticular ornamentation - much reduced _____ - well developed cephalic papillae - _____ tail coiled or w/ spiral flexure. An adult filarial worm lives in the lymphatic part of a human.. These filarial worms infect many parts of the body, such as deep connective tissues and cavities but the adult filarial worm only.
