Carcinogenic parasites are parasitic organisms that depend on other organisms (called hosts) for their survival, and cause cancer in such hosts.Three species of flukes are medically-proven carcinogenic parasites, namely the urinary blood fluke (Schistosoma haematobium), the Southeast Asian liver fluke (Opisthorchis viverrini) and the Chinese liver fluke (Clonorchis sinensis).
The scabies mite Sarcoptes scabiei var. hominis goes through four stages in its lifecycle: egg, larva, nymph, and adult. Upon infesting a human host, the adult female burrows into the stratum corneum (outermost layer of skin), where she deposits two or three eggs per day. These oval eggs are 0.1–0.15 mm (0.0039–0.0059 in) long and hatch as ...

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.
These symptoms can be present across most of the body or just in certain areas such as the wrists, between fingers, or along the waistline. [2] The head may be affected, but this is typically only in young children. [2] The itch is often worse at night. [2] Scratching may cause skin breakdown and an additional bacterial infection in the skin. [2]
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.
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
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 ...
