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 are ways that pathogens can cause disease in their hosts. viruses replicate by inserting their genetic material into a host cell and taking over many of the host cell's functions. bacteria breaks down the tissue of an infected organism for food or release toxins that interfere with normal activity in the host. fungi causes infections on the surface of the skin, mouth, throat, fingernail, and toenails. protists may infect people through contaminated water and insect bites.
