What disease infection is caused by enterobius Vermicularis?
Pinworm infection is caused by a small, thin, white roundworm called Enterobius vermicularis. Although pinworom infection can affect all people, it most commonly occurs among children, institutionalized persons, and household members of persons with pinworm infection.
How does enterobius Vermicularis infect humans?
People become infected, usually unknowingly, by swallowing (ingesting) infective pinworm eggs that are on fingers, under fingernails, or on clothing, bedding, and other contaminated objects and surfaces. Because of their small size, pinworm eggs sometimes can become airborne and ingested while breathing.
What are the possible complications of enterobiasis?
The following complications have also been noted: appendicitis, endometritis, salpingitis, urethritis, urinary tract infection, and vulvovaginitis.
What are the symptoms of Enterobius infections?
What are the symptoms of a pinworm infection?
- frequent and strong itching of the anal area.
- restless sleep due to anal itching and discomfort.
- pain, rash, or other skin irritation around the anus.
- the presence of pinworms in the area of your child’s anus.
- the presence of pinworms in stools.
What disease is caused by pinworms?
Enterobiasis or pinworm infection is a common, contagious, parasitic infestation found mainly in children. The disorder is spread by swallowing or inhaling the tiny eggs of the pinworm. Enterobiasis rarely causes any serious physical problems except for the main symptom, which is severe rectal itching.
Which is the infective form of e Vermicularis?
Enterobius vermicularis (Pinworm) At night, the females migrate out of the body and release eggs on the perianal skin. The eggs become infective within several hours, and the life cycle is completed when the eggs are ingested and hatch, to release the larval form of the worm in the host small intestine.
What are the common names applied to enterobius Vermicularis?
The nematode (roundworm) Enterobius vermicularis is widely known as the human pinworm due to the female’s long, pointed tail. In some areas the common names “seatworm” and “threadworm” are used (the latter of which is sometimes also used to refer to Strongyloides stercoralis).
What are the complications of pinworm infection?
Although rare, other complications of a pinworm infection may include:
- Urinary tract infections.
- Weight loss.
- Infection of part of the abdomen (peritoneal cavity)
Is Enterobius vermicularis a nematode?
Causal Agent. The nematode (roundworm) Enterobius vermicularis is widely known as the human pinworm due to the female’s long, pointed tail. In some areas the common names “seatworm” and “threadworm” are used (the latter of which is sometimes also used to refer to Strongyloides stercoralis).
What is the scientific name of pinworm?

Human pinworm/Scientific names

What is the cause of pinworms?
Accidentally swallowing or breathing in pinworm eggs causes a pinworm infection. The tiny (microscopic) eggs can be carried to your mouth by contaminated food, drink or your fingers. Once swallowed, the eggs hatch in the intestines and mature into adult worms within a few weeks.
Is pinworm an infectious disease?
Pinworm infestation is the most common helminthic infection in the United States, occurring in an estimated 20 to 42 million people. Most cases are in school-aged and young children, their family members, or caregivers.
Who is the natural host of Enterobius vermicularis?
Enterobius vermicularis or pinworm is one of the most prevalent nematode infections in the world. The original name of E. vermicularis was Oxyuris vermicularis. Human beings are the natural host for this infection. Children are more prone to such infestations.
How big is the egg of Enterobius vermicularis?
The typical Enterobius vermicularis egg measures 48 to 60 µm in length by 20 to 35 µm in width. The somewhat oval egg is characteristically flattened on one side. The egg consists of a developing larva surrounded by a conspicuous double-layered, thick-walled colorless shell. The egg may be seen at various stages of development.
How is Dientamoeba fragilis transmitted by Enterobius vermicularis?
The transmission of Dientamoeba fragilis is thought to be facilitated by Enterobius vermicularis. According to this theory, the D. fragilis trophozoite may take up residence inside the pinworm egg and transmit the disease. Both organisms have been found to cause infections. Morphology of Enterobius vermicularis
Which is the best treatment for e.vermicularis?
Treatment Albendazole, mebendazole, or pyrantel pamoate are the most effective treatments for E. vermicularis eradication. It’s worth noting that, in many cases, treatment is recommended for infected individuals’ family members due to the ease with which pinworm eggs spread into the environment.
