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 ]
The house fly is found all over the world where humans live and so is the most widely distributed insect. [1]This is a list of common household pests – undesired animals that have a history of living, invading, causing damage, eating human foods, acting as disease vectors or causing other harms in human habitation.
How myiasis affects the human body depends on where the larvae are located. Larvae may infect dead, necrotic (prematurely dying) or living tissue in various sites: the skin, eyes, ears, stomach and intestinal tract, or in genitourinary sites. [5] They may invade open wounds and lesions or unbroken skin. Some enter the body through the nose or ears.
This leaf-footed bug climbs wind blown grass and flies off. Insects (from Latin insectum) are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae.
Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
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.
Tungiasis is an inflammatory skin disease caused by infection with the female ectoparasitic Tunga penetrans, a flea also known as the chigoe, chigo, chigoe flea, chigo flea, jigger, nigua, sand flea, or burrowing flea (and not to be confused with the chigger, a different arthropod).
Bed bug bites may lead to skin changes ranging from small areas of redness to prominent blisters. [1] [2] Symptoms may take between minutes to days to appear and itchiness is generally present. [2] Some individuals may feel tired or have a fever. [2] Typically, uncovered areas of the body are affected. [2]
