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]
Severe cases can cause heart failure and brain inflammation, but the disease can also go undetected for years at a time. Some 11,000 people died from the disease every year. More on AOL:
Thread-legged bugs – subfamily Emesinae, including the genus Emesaya Kissing bugs (or cone-headed bugs) – subfamily Triatominae , unusual in that most species are blood-suckers and several are important disease vectors
The word cochineal is derived from the French cochenille, derived from Spanish cochinilla, in turn derived from Latin coccinus, from Greek κόκκινος kokkinos, "scarlet" from κόκκος kokkos (Latin equivalent coccum) referring in this case either to the oak berry (actually the insects of the genus Kermes) or to a red dye made from the crushed bodies thereof.

The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. In some cases this is enough to kill a predator. [6] The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates.
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.
Bed bug nymph, Cimex lectularius, engorged with human blood. Chagas disease is a modern-day tropical disease caused by Trypanosoma cruzi and transmitted by kissing bugs, so-called because they suck human blood from around the lips while a person sleeps. [92] The bed bug, Cimex lectularius, is an external parasite of humans. It lives in bedding ...
