Roundworms are worms that live inside the body of other organisms causing diarrhea and fever. They range in size from a few millimeters to two meters of length. Common examples of roundworms are: Ascaris Rishta, Pinworm (Enterobius vermicularis).
Research shows about more than 60 species of such parasitic worms and found that reside in human beings. They mainly live in the human digestive system especially in the intestine, but may travel to other sites throughout the body.
Parasitic Roundworms Human Ascaris (Ascaris lumbricoides), parasitic in the small intestine. This is a large helminth: females up to 40 cm, males up to 25 cm. In females, the posterior end is straight, in males it is pointed and bent to the ventral side. The female roundworm lays more eggs per day. Roundworm eggs need to get into the external environment, for the development of larvae inside the egg, oxygen, a certain humidity, and a sufficiently high temperature are needed.
Eggs are covered with several protective shells and are able to remain viable for up to 10 years. Under favorable conditions, a larva forms in the egg within a day. Such an egg is called invasive. Infection of people occurs when eating vegetables and fruits contaminated with ascaris eggs. The development of roundworms occurs without a change of owners. In the small intestine, the larvae are released from the shell, pierce the intestinal mucosa with an elastic body and enter the bloodstream.
Roundworms are a type of parasitic biohazards
Roundworms are contagious and parasitic biohazards. With the blood flow, they enter the heart, and from there to the lungs. In the alveoli of the lungs, they are for some time in an environment rich in oxygen. From the lung tissue, they penetrate into the bronchi, from them into the trachea, and then into the pharynx and are swallowed again. Migration of larvae lasts 9-12 days. During this time, the larvae grow and molt several times. Once in the intestine for the second time, the larvae grow within 3 months and turn into sexually mature individuals. The life span of Ascaris is about 1 year.
Ascaris is a dangerous human parasite. It poisons the human body with poisonous products of its metabolism and, penetrating into various organs and cavities, mechanically damages them. A large amount of them can cause blockage of the intestines.

Roundworms also include the human pinworm (Enterobius vermicularis), which parasitizes in the lower parts of the small intestine and in the large intestine. Adult worms are small, females up to 12 mm, males up to 5 mm. Females lay their eggs on the skin near the anus, causing itching. Once under the nails, the eggs can easily get into the baby’s mouth. They become invasive after 4-6 hours. In the small intestine, larvae emerge from them, which migrate to the initial sections of the large intestine and reach sexual maturity after 2 weeks.
Rishta is a dangerous human parasite that forms subcutaneous abscesses. It reaches a length of up to 1 m. The larva must get into the water, where it penetrates into the intermediate host – the cyclops. Human infection occurs by drinking raw water containing infected cyclops. Bancroft’s filament causes “elephantiasis” in a person, parasitizing in the lymphatic vessels and clogging them, they prevent the outflow of lymph.
Among plant parasites, the best known are beet, onion, potato, wheat and other nematodes. They inhibit growth, reduce the yield of agricultural crops, and in the event of a severe defeat, they also cause their death. These include water purification, veterinary and sanitary control over the quality of meat, cleaning settlements, preventing the use of untreated feces as fertilizers.
