These findings, coupled with recent work showing that gliadin has an innate response component, suggest that gliadin may be more responsible for the primary manifestations of coeliac disease, whereas tTG is a bigger factor in secondary effects such as allergic responses and secondary autoimmune diseases. In a large percentage of people with coeliac, the anti-tTG antibodies also recognise a rotavirus protein called VP7. These antibodies stimulate monocyte proliferation, and rotavirus infection might explain some early steps in the cascade of immune cell proliferation.Indeed, earlier studies of rotavirus damage in the gut showed this causes villous atrophy. This suggests that viral proteins may take part in the initial flattening and stimulate self-crossreactive anti-VP7 production. Antibodies to VP7 may also slow healing until the gliadin-mediated tTG presentation provides a second source of crossreactive antibodies. Other intestinal disorders may have biopsy that look like coeliac disease including lesions caused by Candida. Villous atrophy and malabsorption
The inflammatory process, mediated by T cells, leads to disruption of the structure and function of the small bowels mucosal lining and causes malabsorption as it impairs the bodys ability to absorb nutrients, minerals, and fat-soluble vitamins A, D, E, and K from food. Lactose intolerance may be present due to the decreased bowel surface and reduced production of lactase but typically resolves once the condition is treated. Alternative causes of this tissue damage have been proposed and involve the release of interleukin 15 and activation of the innate immune system by a shorter gluten peptide (p31–43/49).
Membranes and bag and cartridge filters remove Cryptosporidium  product-specifically.While Cryptosporidium is highly resistant to chlorine disinfection, with high enough concentrations and contact time, Cryptosporidium will be inactivated by chlorine dioxide and ozone treatment. The required levels of chlorine generally preclude the use of chlorine disinfection as a reliable method to control Cryptosporidium in drinking water. Ultraviolet light treatment at relatively low doses will inactivate Cryptosporidium. Water Research Foundation-funded research originally discovered UVs efficacy in inactivating Cryptosporidium.One of the largest challenges in identifying outbreaks is the ability to identify Cryptosporidium in the laboratory. Real-time monitoring technology is now able to detect Cryptosporidium with online systems, unlike the spot and batch testing methods used in the past.The most reliable way to decontaminate drinking water that may be contaminated by Cryptosporidium is to boil it.In the US the law requires doctors and labs to report cases of cryptosporidiosis to local or state health departments. These departments then report to the Center for Disease Control and Prevention. The best way to prevent getting and spreading cryptosporidiosis is to have good hygiene and sanitation. An example would be hand-washing. Prevention is through washing hands carefully after going to the bathroom or contacting stool, and before eating. People should avoid contact with animal feces. They should also avoid possibly contaminated food and water.
