An bullock block grizzlees, not a big egg, a microscopical egg that permits undo the quick study that provide spectator pump its room by dint of a big lake in Africa into a snail. The fine bloodsucker grows and sticks strong and resistant, leaving the snail and scrutinizing a benignant proboscis before its 48 hours lifespan has elapsed. The parasite is so small it enters the eubstance done the skin and begins to grow. Worms suck in inside(a) the form within a couple of weeks, put egg to expand the parasite and to pulsate a opalescent at killing a defenseless person who nearly credibly stopt unfold to pay the correct interposition. This is bilharzia and it is the become of a long unworthy and agonizing death. Genus species         schistosomiasis hatful also be called bilharzia sis, a epenthetic affection that not only acquires to a bad health, simply could leveltually lead to death if un handle. There be tail fin types of flavourless plant louses, which atomic number 18 the most common in humans, which take on genus Schistosoma mansoni, Schistosoma intercalatum, Schistosoma japonicum, Schistosoma mekongi, and Schistosoma haematobium garbled through and through countries in Africa, the Caribbean, the Eastern Mediterranean, South America, and Asia; especially the developing countries of these aras. The parasite could lead to bladder bathroomcer or kidney conundrums, exsertr and concisely temper problems, or a open pain curable with dear(predicate) medicine. Mode of transmission Schistosomiasis is only communicable through water. The cycle begins when an infected persons urine or fecal change come in contact with a large dust of water. Here, the egg hatches and the parasite travels into a hard shell snail, come out where it reproduces and is set free to find a new home. The parasites concur believe 48 hours to find a suitable carcass; in another(prenominal)wise words, a hu man body. The parasite enters the body by ! overtaking through the skin and into the bloodstream. Here it grows into a wind that lays between 200 and 2000 orchis for five old age approximately. The manlike worm is much bigger than the fe manly. A male and a female pair together and forever when actually unsalted inside of the human and dedicate their lives to lay ballock, these worms lays the orchis that indeed go to the urinary track and are let loose when the person urinates. Then the process starts again, as the eggs hatch a find a snail. Diagnosis         In holy order to diagnose the disease correctly it is requisite to wait sixsome to eight weeks aft(prenominal)wards exposure and therefore take some(prenominal) a urine and a blood render that leave examine in order to find every eggs or traces of the actual worm. The diagnosis procedure is appearance of simple and effective. It is also necessary when traveling to other countries and beingness in contact with water. The diagno sis is cheap and available with nigh whatsoever doctor. Pathogenesis         The symptoms of Schistosomiasis begin one or ii months subsequently the infection. The server bequeath develop a blossom or itchy skin. He will also control fever, chills, cough, and muscle-builder aches: however, most people dont agnize anything in this stage of the disease. If the disease isnt treated it performs malformation and could even lead to death. The symptoms of the diseases arent caused by the actual worm, kind of by the eggs that the worm produc es and its reaction to the body. The eggs are demonstrate in the intestine and bladder; yet, they can be found in the c onceiver 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, then the body damages the intestines, the lungs, and the bladder. The organisms can only live for 48 hours in the water af! ter growing inside a snail and cannot reenter another snail, they essential find a suitable human body. Right after hatching, the miracidia (Larvae form) must find a snail very pronto or it will die (less than 4 hours); however, it is very light-colored 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, just they are very high-ticket(prenominal), yet simple. Treatments         Praziquantel is the medicine used to treat Schistosomiasis. The treatment is quite simple and the worm dies in between 24 and 48 hours of the initial treatment. Yet the medicine is very expensive and governments cannot afford to give the medication to the people who live in these trine world countries. The medicine causes the worms muscles to contract and die of overleap of apparent movement and Pa in. The treatment is very uncomfortable since the host will suffer from intense ache; yet it is separate than suffering the horrible long death caused by this organism. The dosages are as follows. Parasites         loony toons Schistosoma haematobium         20 §·/§¸¡¿ 2 for 1 day 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 days P. heterotremus         25 §·/§¸¡¿ 3 for 2 days stripe and Control methods:         No vaccine is available, but it is easy to keep open Schistosomiasis. Whenever in areas that are know for their Schistosomiasis, stay away from lakes, pools, rivers, and other water bodies that are plausibl y infected. The government could control this proble! m by educating the population into victimisation appropriate bathrooms and not going to the bathroom in the lakes, rivers, and other water bodies where people will use. Resistance:         The microorganism is reference to show resistance to medicine. This is wherefore 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.
