In this case, the adult hair follicle is located in the conjunctival sac. However, if the hair gets into the eye, ocular loalosis occurs - it is more serious but at the same time rarer. If the infection is localized only in the subcutaneous tissue, the disease is not very dangerous. edema occurs around these bumps, as a result of an allergic reaction to irritation by the parasite. Subcutaneous loalosis is manifested by the parasites forming lumps in the subcutaneous tissue. The disease caused by eye lice is called loalosis and is divided into subcutaneous and ocular types. The females then give birth to larvae (microfilariae), which then circulate in the blood and can be sucked in by a stinging fly. The larvae of the vlasovka reach the subcutaneous tissue or the eye conjunctiva through the blood, where they mature and reproduce. A person becomes infected when bitten by an insect. Its intermediate host is a bug and its definitive host is man. Direct microscopic evidence is used in the diagnosis - larvae are detected in blood taken at night using the thick drop method.Įyeworm is a parasite found mainly in Central Africa. It causes the disease "brugiosis", which mainly affects the upper and lower limbs and can manifest as elephantiasis. bancrofti - life cycle, transmission, disease and therapy. Prevention is especially important - elimination of mosquitoes.īrugia malayi (Malaysian hairworm) īrugia malayi is very similar to W. The disease is treated with diethylcarbamazine or ivermectin. The diagnosis uses direct microscopic evidence of microfilariae from the blood or punctate from the nodes of the patient. The main symptoms of wuchereriosis include abdominal pain, swelling, vomiting, anemia and in more severe stages, when the lymphatic vessels burst, chyluria (the presence of lymph in the urine) may also occur.Ī more serious form is elephantiasis, when the flow of lymph is blocked and the given part of the body increases as a result - the lower limbs, scrotum and vulva are most often affected. Adult hairworms most often parasitize in the lymphatic system and can clog lymphatic vessels for several years, which subsequently leads to lymph stagnation and the formation of lymphatic varices and a lymphatic vessel may even burst.
