In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching. These relatives of ticks are nearly microscopic, measuring 400 μm (1/60 of an inch) and have a chrome-orange hue. [9] [10] There is a marked constriction in the front part of the body in the nymph and adult stages.
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 ]
Triatoma infestans, commonly called winchuka [1] or vinchuca [2] in Argentina, Bolivia, Uruguay and Chile, barbeiro in Brazil, chipo in Venezuela and also known as "kissing bug" or "barber bug" in English, is a blood-sucking bug (like virtually all the members of its subfamily Triatominae) and the most important vector of Trypanosoma cruzi which can lead to Chagas disease.
Trombicula, known as chiggers, red bugs, scrub-itch mites, or berry bugs, are small arachnids [2] (eight-legged arthropods) in the Trombiculidae family. In their larval stage, they attach to various animals and humans, then feed on skin, often causing itching and trombiculosis . [ 3 ]
Symptoms to note: Bee stings cause moderate pain, which should subside within a few hours. All insect stings can cause life-threatening allergic reactions, and bee stings are no exception.
Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
Infectious bugs are getting stronger and more resistant to drugs. Because of that, a British government-commissioned review released Thursday says these "superbugs" could lead to more than 10 ...
Cancer generally is a disease of many years lived, so I watch in puzzlement as the illness strikes people I now consider young, people under 50. In late March, cancer killed an excellent local ...
