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.
The two main types of intestinal parasites are helminths and protozoa. Helminths are worms with many cells. Tapeworms, pinworms, and roundworms are among the most common helminths in the United States.In their adult form, helminths cannot multiply in the human body. Protozoa have only one cell, and can multiply inside the human body, which can allow serious infections to develop.Intestinal parasites are usually transmitted when someone comes in contact with infected feces (for example, through contaminated soil, food, or water).rotozoa have only one cell, and can multiply inside the human body, which can allow serious infections to develop.
