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.
Parasitic infections can be caused by three types of organisms: protozoa; helminths; ectoparasites; Protozoa are single-celled organisms that can live and multiply inside your body. Some infections caused by protozoa include giardiasis. This is a serious infection that you can contract from drinking water infected with Giardia protozoa.
