A parasitic disease, also known as parasitosis, is an infectious disease caused by parasites. [1] Parasites are organisms which derive sustenance from its host while causing it harm. [ 2 ] The study of parasites and parasitic diseases is known as parasitology . [ 3 ]
The disease affects both humans (and animals) and is primarily found in regions where people consume raw or undercooked freshwater fish such as in East Asia, Siberia, Manchuria, the Balkan states, Israel and Spain. Metagonimiasis is caused by the ingestion of infected raw or undercooked freshwater fish such as trout, salmon, or chub. The ...
Cryptosporidiosis, sometimes informally called crypto, [1] is a parasitic disease caused by Cryptosporidium, a genus of protozoan parasites in the phylum Apicomplexa.It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune ...
Sandfly species transmit the disease leishmaniasis, by acting as vectors for protozoan Leishmania species, and tsetse flies transmit protozoan trypansomes (Trypanosoma brucei gambiense and Trypansoma brucei rhodesiense) which cause African Trypanosomiasis (sleeping sickness). Ticks and lice form another large group of invertebrate vectors.

Establishing the viral etiology took many decades due to the difficulty of growing the virus in cell culture. In the 1940s and 1950s in the United States and Japan, caliciviridae could not be grown in culture, but as an experiment bacterial free filtrate of diarrhea was given to volunteers to check if viruses were present in volunteers' stool.
