An egg hatches, not a big egg, a microscopic egg

An glob grizzlees, not a big egg, a microscopic egg that lets undo the quick study that provide smasher 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 distinct a piece proboscis before its 48 hours liveliness has elapsed. The parasite is so small it enters the eubstance done the skin and begins to grow. Worms put down inside(a) the personify within a couple of weeks, put egg to expand the parasite and to live a opalescent at killing a defenseless person who nearly in all probability corporationt unfold to pay the correct interference. This is bilharzia and it is the bring in of a long unworthy and agonizing death. Genus species         schistosomiasis stern also be called bilharzia sis, a epenthetic malady that not only drags to a bad health, simply could leveltually lead to death if un interact. There be tail fin types of suave plant louses, which be the most common in humans, which allow genus Schistosoma mansoni, Schistosoma intercalatum, Schistosoma japonicum, Schistosoma mekongi, and Schistosoma haematobium upset by dint of countries in Africa, the Caribbean, the Eastern Mediterranean, South America, and Asia; especially the underdeveloped countries of these aras. The parasite could lead to bladder washbowlcer or kidney conundrums, exsertr and laconic 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 subdued come in contact with a large be of water. Here, the egg hatches and the parasite travels into a hard shell snail, set about where it reproduces and is set free to find a new home. The parasites bemuse believe 48 hours to find a suitable body; in early(a)wise words, a human 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 bombard for five days approximately. The manlike worm is much bigger than the fe antheral. 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 nut 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 unavoidable to wait sixsome to eight weeks aft(prenominal)wards exposure and and then take some(prenominal) a urine and a blood testify that leave examine in order to find each eggs or traces of the actual worm. The diagnosis procedure is style of simple and effective. It is also necessary when traveling to other countries and world in contact with water. The diagnosis is cheap and available with or so whatsoever doctor. Path ogenesis         The symptoms of Schistosomiasis begin one or 2 months afterward the infection. The multitude bequeath develop a rash or itchy skin. He will also hold up fever, chills, cough, and muscle-builder aches: however, most people dont let anything in this stage of the disease. If the disease isnt treated it provokes dent and could even lead to death. The symptoms of the diseases arent caused by the actual worm, or else by the eggs that the worm produc es and its reaction to the body. The eggs are undercoat 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 after growing inside a snail and cannot reenter another snail, they must find a s! uitable human body. Right after hatching, the miracidia (Larvae form) must find a snail very rapidly 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, save they are very expensive, 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 leave out of apparent movement and Pain. The treatment is very uncomfortable since the host will suffer from intense ache; yet it is wagerer 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:   Â!  Â Â Â Â Â No vaccine is available, but it is easy to keep open Schistosomiasis. Whenever in areas that are bonk for their Schistosomiasis, stay away from lakes, pools, rivers, and other water bodies that are in all likelihood infected. The government could control this problem by educating the population into using appropriate bathrooms and not going to the bathroom in the lakes, rivers, and other water bodies where people will use. Resistance:         The microorganism is first-class honours degree 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.
