must use contaminated water to drink or bathe. The life cycle of the worm is a relatively simple one. The worm starts off by producing larvae into stagnant water‚ where the larvae thrive. While the larvae live in the water‚ a person then may accidentally drink them‚ since filtering water is a difficult process in poor countries. Once in the body‚ the larvae mature into full grown worms by stealing nutrients throughout the human body it is inhabiting. After about a year‚ the worm (or even worms)

Cats become infected with the larvae either through skin contact with an infected cat’ stool in the dirt‚ sand or litter box‚ through the ingestion of other animals who are infected with hookworms or by drinking water that is infested with the larvae. Kittens can become infected with hookworms by drinking their mother’s milk. Once inside of the cat’s body‚ the larvae migrate to the lungs and then into the small intestine. While in the small intestine‚ the larvae will mature into adult worms where

The research team began with the observation that females bees who are fed royal jelly while a larvae become queen bees‚ while females not fed royal jelly become normal worker bees. The research team then worked from the hypothesis that there is something in royal jelly that when eaten‚ epigenetically affects methylation of DNA in the female so that

LIFE CYCLE Humans become infected by drinking unfiltered water containing copepods (small crustaceans) that have been infected with D. medinensis larvae. After ingestion‚ the copepods die and release the stage 3 larvae‚ which then penetrate the host ’s stomach or intestinal wall‚ and enter into the abdominal cavity and retroperitoneal space. After maturing‚ adult male worms die while the females migrate in the subcutaneous tissues

uncooked food contaminated by soil containing eggs of the worm. A person becomes infected after accidentally swallowing the eggs. The eggs hatch into larvae within the person’s intestine. The larvae penetrate the intestine wall and reach the lungs through the blood stream. They eventually get back to the throat and are swallowed. In the intestines‚ the larvae develop into adult worms. The female adult worm which can grow to over 30cm in length‚ lays eggs that are then passed into the faeces. If soil is
