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.
Malaria is caused by infection with a microbe called a protozoan, which is transferred to people though the bite of Anopheles mosquitoes. Distinct from viruses and bacteria, protozoans are single-celled eukaryotic micro-organisms. Four species of protozoan parasites cause malaria in humans â Plasmodium falciparum, P. vivax, P. ovale and P. malariae.
