Arthropods are common vectors of disease. A vector is an organism which spreads disease-causing parasites or pathogens from one host to another. Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms.
A zoonosis (/ z oʊ ˈ ɒ n ə s ɪ s, ˌ z oʊ ə ˈ n oʊ s ɪ s / ⓘ; [1] pl.: zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human.

Entamoeba histolytica is a pathogenic parasite known to cause amoebiasis, which is the third leading cause of parasitic deaths. [20] It is diagnosed by the assessment of stool samples. [ 21 ] Amoebiasis is caused by the ingestion of food or water contaminated with feces or other bodily wastes of an infected person, which contain cysts, the ...

Coccidiosis is a parasitic disease of the intestinal tract of animals caused by coccidian protozoa. The disease spreads from one animal to another by contact with infected feces or ingestion of infected tissue. Diarrhea, which may become bloody in severe cases, is the primary symptom.
Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. [1] They are caused by infection with a variety of pathogens , including rickettsia and other types of bacteria , viruses , and protozoa . [ 2 ]
Several articles, recent to early 2014, warn that human activities are spreading vector-borne zoonotic diseases. [a] Several articles were published in the medical journal The Lancet, and discuss how rapid changes in land use, trade globalization, climate change and "social upheaval" are causing a resurgence in zoonotic disease across the world ...
