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.
What is schistosomiasis and what causes it? Schistosomiasis is also known as Bilharzia. It is a tropical disease caused by a parasitic infection with worms from the Schistosomatidae family. A parasite is an animal that lives on or in another animal and feeds from it. There are three main worm species that cause schistosomiasis in humans: Schistosoma haematobium; Schistosoma mansoni; Schistosoma japonicum; Eggs from the mature worms are passed out (excreted) in the poo (faeces) or urine of an infected person. These eggs can get into fresh water if it is contaminated with human sewage.
