1 In men with established coronary heart disease, consumption of 1-14 alcoholic drinks per week, including wine, doesn't seem to have any effect on heart disease or all-cause mortality compared with men who drink less than one drink per week.
Terminology [edit]. Although organisms such as bacteria function as parasites, the usage of the term parasitic disease is usually more restricted. The three main types of organisms causing these conditions are protozoa (causing protozoan infection), helminths (helminthiasis), and ectoparasites.ome parasites like Toxoplasma gondii and Plasmodium spp. can cause disease directly, but other organisms can cause disease by the toxins that they produce.
How Do Parasitic Diseases Spread? In most cases, people get a parasitic infection by bathing in, swimming in, or drinking water that contains parasites; by eating food that has not been cooked thoroughly; or by coming into contact with untreated sewage. That commonly can happen when human waste is used to fertilize fields.
