1 Filariasis Nematoda Systemic round worms
2 Filaria -a roundworm -Adult filaria live in body cavities, lymphatics, and subcutaneous tissues -embryos (microfilaria) live in blood or dermis -all require an insect or crustaean vector -microfilaria ( µ long) - adults 2 cm 120 cm (4 10 µ wide)
3 Filaria 1. Onchocerca volvulus - river blindness - black fly 2. Wuchereria bancrofti - lymphatic filariasis - mosquito Brugia malayi 3. Loa Loa - eye worm - deer fly 4. Dracunculus medinensis - Guinea worm - cyclops 5. Mansonella perstans - midge 6. Mansonella ozzardi - midge
