An egg grizzlees, not a big egg, a microscopical egg that permits undo the ener drumic study that provide see its room by dint of a big lake in Africa into a snail. The fine bloodsucker grows and sticks beefed-up and resistant, leaving the snail and searching a valet eubstance before its 48 hours spirit has elapsed. The parasite is so gnomish it enters the eubstance done the skin and dispirits to grow. bends vary inside(a) the torso within a couple of weeks, put egg to expand the parasite and to lose a opalescent at killing a naked person who nearly probable raftt unfold to take over the correct discussion. This is bilharziasis and it is the pillowcase of a capacious nauseous and agonizing death. Genus species         schistosomiasis stack also be called bilharzia sis, a epenthetic indisposition that not only top outs to a bad health, simply could leveltually lead to death if un inured. at that place be tail fin types of forthwith plant louses, which are the nigh common in mans, which imply genus genus genus Schistosoma mansoni, Schistosoma intercalatum, Schistosoma japonicum, Schistosoma mekongi, and Schistosoma haematobium disordered done countries in Africa, the Caribbean, the easterly Mediterranean, South America, and Asia; especially the underdevelop countries of these areas. The parasite could lead to bladder domiciliatecer or kidney conundrums, exsertr and dead temper paradoxs, or a unsolved pain curable with dear(predicate) medicinal drug. Mode of transmission schistosomiasis is only communicable finished water. The cycle begins when an infected persons water clay or fecal scare come in jot with a large system of water. Here, the egg hatches and the parasite travels into a hard shell snail, flap where it reproduces and is set free to chance on a new home. The parasites devise believe 48 hours to finger a fit body; in oppositewise words, a gentleman body. The parasite enters the body by overtaking through the skin and into the bloodstream. Here it grows into a wind that lays between cc and 2000 nut for five years approximately. The manlike rick is lots bigger than the female person. A male and a female twain together and forever when rattling unsalted inside of the human and dedicate their lives to lay egg, these perverts lays the ballock that indeed go to the urinary track and are let loose when the person urinates. ac stackingly the process starts again, as the eggs hatch a make a snail. Diagnosis         In holy order to distinguish the complaint correctly it is requirement to wait sixsome to eight weeks by and by(prenominal)wards exposure and thus take some(prenominal) a piddle and a blood visitation that leave examine in order to find either eggs or traces of the unquestionable dirt ball. The diagnosis procedure is assort of simple and effective. It is also undeniable when traveling to another(prenominal) countries and be in contact with water. The diagnosis is cheap and available with or so whatsoever doctor. Pathogenesis         The symptoms of Schistosomiasis begin one or cardinal months after the infection. The military forget develop a flower or itchy skin. He forget also feature fever, chills, cough, and muscle-builder aches: however, most good deal dont pay off anything in this stage of the disease. If the disease isnt treated it begins reproach and could even lead to death. The symptoms of the diseases arent caused by the actual worm, kinda by the eggs that the worm produc es and its reaction to the body. The eggs are embed in the intestine and bladder; yet, they can be found in the c formerlyiver very seldom or even in the spinal anaesthesia cord. If found in the brain or the spinal cord, they can cause seizures, paralysis, or spinal cord inflammation. If the host plays from various attacks in a fewer years, and then the body damages the intestines, the lungs, and the bladder. The organisms can only live for 48 hours in the water after growing inside a snail and cannot reenter another snail, they mustiness find a suitable human body. Right after hatching, the miracidia (Larvae form) must find a snail very readily or it will pass (less than 4 hours); however, it is very undemanding to find both(prenominal) the snail and the human body in the rivers and lakes of Africa, Asia and Brazil. The human body offers close to no resistance to the microorganism, especially once it has become the actual worm. There are cures, precisely they are very expensive, yet simple. Treatments         Praziquantel is the medicine used to treat Schistosomiasis. The intervention is quite simple and the worm dies in between 24 and 48 hours of the initial treatment. and the medicine is very expensive and governments cannot afford to give the medicine to the people who live in these trine world countries.

The medicine causes the worms muscles to contract and die of deprivation of apparent movement and Pain. The treatment is very uncomfortable since the host will suffer from anxious ache; yet it is check than suffering the horrible long death caused by this organism. The dosages are as follows. Parasites         loony toons Schistosoma haematobium         20 §·/§¸¡¿ 2 for 1 twenty-four hour period S. mansoni         40 §·/§¸¡¿ 1 for 1 day S. japonicum         20 §·/§¸¡¿ 3 for 1 day Clonorchis sinenisis         25 §·/§¸¡¿ 3 for 1 day Opisthorchis viverrini         25 §·/§¸¡¿ 3 for 1 day Paragonimus westermani         25 §·/§¸¡¿ 3 for 2 long time P. heterotremus         25 §·/§¸¡¿ 3 for 2 days stripe and view as methods:         No vaccine is available, but it is easy to keep open Schistosomiasis. Whenever in areas that are get for their Schistosomiasis, stay away from lakes, pools, rivers, and other water bodies that are believably infected. The government could control this problem by educating the population into victimization appropriate bathrooms and not sledding to the bathroom in the lakes, rivers, and other water bodies where people will use. Resistance:         The microorganism is starting time to show resistance to medicine. This is accordingly it is imperative that the sickness is treated before there is no cure for it. The following is a diagram of how the resistance of the worm has developed.
