Causes. Giardia parasites live in the intestines of people and animals. Before the microscopic parasites are passed in stool, they become encased within hard shells called cysts, which allows them to survive outside the intestines for months.Once inside a host, the cysts dissolve and the parasites are released.auses.

On the other hand, those people who eat a lot of processed foods, and/or non-organic foods are susceptible to developing these health issues due to GMOs. For example, about 90% of the corn and soy in the United States is genetically modified. And a lot of processed foods have corn and soy ingredients.
These genetic diseases include mtDNA depletion syndromes such as Alpers or early infantile hepatocerebral syndromes, and mtDNA deletion disorders, such as progressive external ophthalmoplegia (PEO), ataxia-neuropathy, or mitochondrial neurogastrointestinal encephalomyopathy (MNGIE).his review focuses on our current knowledge of genetic defects of mtDNA replication (POLG, POLG2, C10orf2) and nucleotide metabolism (TYMP, TK2, DGOUK, and RRM2B) that cause instability of mtDNA and mitochondrial disease.
