Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.
Protozoan infections are responsible for diseases that affect many different types of organisms, including plants, animals, and some marine life. Many of the most prevalent and deadly human diseases are caused by a protozoan infection, including African sleeping sickness, amoebic dysentery, and malaria.
This article contains a list of insect-borne diseases. They can take the form of parasitic worms , bacteria , protozoa , viruses , or the insects directly acting as a parasite. Insect-borne diseases
Scarabiasis, or "beetle-disease", is a condition where beetles temporarily infest the digestive tract of other animals. It can also affect humans, and despite being a rare phenomenon, [1] it is the second most important insectal disease in humans after myiasis, which is caused by the larva of flies. The term is commonly used as a synonym of ...
When ants bite humans, it grabs the skin and also sprays a compound called formic acid, Frye explains. Ant bites tend to be small, swollen bumps that appear in clusters, Kassouf says.
Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called "kissing bugs". [4] When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. [ 5 ]
Filariasis is a filarial infection caused by parasitic nematodes (roundworms) spread by different vectors.They are included in the list of neglected tropical diseases.. The most common type is lymphatic filariasis caused by three species of Filaria that are spread by mosquitoes.
In rare cases, deer flies can pass on the bacterial disease tularemia (which can cause a painful ulcer), and blackfly bites can lead to a flu-like condition called “blackfly fever.” Citron ...
