Organophosphate poisoning
Organophosphate pesticides are one of the top causes of poisoning worldwide, with an annual incidence of poisonings among agricultural workers varying from 3-10% per country.
Glucose-6-phosphate dehydrogenase deficiency
G6PD deficiency is the second most common human enzyme defect after ALDH2 deficiency, being present in more than 400 million people worldwide. G6PD deficiency resulted in 4,100 deaths in 2013 and 3,400 deaths in 1990. African, Middle Eastern and South Asian people are affected the most, including those who have these ancestries.
In vitro studies have shown that the "Plasmodium falciparum" is very sensitive to oxidative damage. This is the basis for another theory, that is that the genetic defect confers resistance due to the fact that the G6PD-deficient host has a higher level of oxidative agents that, while generally tolerable by the host, are deadly to the parasite.
