Diagnosis is often made by visible recognition of the worm moving through the tissue of the buccal cavity by either patient or doctor. Also, recovery of worm from patient is also a diagnostic technique. Microscopic identification of worm removed from patient's mouth or tissue is another diagnostic technique for determining the parasite infection.
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 gold standard for diagnosis is the identification of trypanosomes in a sample by microscopic examination. Samples that can be used for diagnosis include ulcer fluid, lymph node aspirates, blood, bone marrow, and, during the neurological stage, cerebrospinal fluid. Detection of trypanosome-specific antibodies can be used for diagnosis, but ...
Scabies (/ ˈ s k eɪ b iː z, ˈ s k eɪ b i iː z /; [10] also sometimes known as the seven-year itch) [1] is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, [1] [3] variety hominis.
Demodex folliculorum is a microscopic mite that can survive only on the skin of humans. [2] [3] Most people have D. folliculorum on their skin.Usually, the mites do not cause any harm, so are considered an example of commensalism rather than parasitism; [4] but they can cause disease, known as demodicosis.
When mast cells build up in the body and something happens to trigger them, like drinking alcohol or an insect sting, they can cause allergic reaction-like symptoms or extreme inflammation, which ...
Human scabies mite seen under an optical microscope (x20) The Italian biologists Giovanni Cosimo Bonomo and Diacinto Cestoni showed in the 17th century that scabies is caused by Sarcoptes scabiei ; this discovery of the itch mite in 1687 marked scabies as the first disease of humans with a known microscopic causative agent.
