Overview

An adult pinworm generally is 1/4 to 1/2 inch (about 6 to 13 millimeters) in length. The most common symptom of infection is anal itching, particularly at night, as worms migrate to the host's anal area to lay their eggs.

Causes

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.

Complications

Typical pinworm infections don't cause serious problems. In rare circumstances, heavy infestations can cause infection of female genitals.

Prevention

Pinworm eggs can cling to surfaces, including toys, faucets, bedding and toilet seats, for two weeks. So besides regular cleaning of surfaces, methods to help prevent the spread of pinworm eggs or to prevent reinfection include:

What are pinworms?

Pinworms are white, parasitic worms that can live in the large intestine of humans. They are about one-half inch long. While the infected person sleeps, female pinworms leave the intestinal tract and lay their eggs on the skin around the anus.

How do the pinworm eggs look?

Symptoms of enterobiasis

In people infected with pinworm eggs, signs characteristic of this pathology appear. Symptoms depend on the number of parasites and the characteristics of the patient's body. Most often, patients complain about such problems:

Eggs of pinworms in children

The most common type of worms, which causes the development of enterobiasis, are pinworms. Oyster eggs in children are diagnosed more often than in other categories of the population. Such statistics are related to the peculiarities of infection by parasites.

Diagnostics

To identify parasitic infection, the patient must pass the appropriate tests. Diagnosis is carried out using microscopy of perianal scrapings. Analysis for enterobiasis should be done in the morning before defecation and before hygiene procedures.

Blank for scraping eggs on pinworm eggs

Taking perianal scrapings for enterobiasis is a mandatory procedure for both adults and children. The analysis is appointed in such cases:

Analysis for pinworm eggs

In the presence of symptoms characteristic for helminthic invasion, it is necessary to consult a doctor (therapist, infectious disease specialist) and undergo diagnostics. An analysis for egg pinworm can be carried out in a clinic or at home. To do this, use a method of adhesive tape or scraping. In some cases, the delivery of feces is prescribed.

How to take an analysis for pinworm eggs?

Getting the direction for the diagnosis of helminthic invasion, you need to know how to pass the analysis on the eggs of pinworms. First of all, you should properly prepare for the study:

E. vermicularis is the most prevalent gastrointestinal nematode in humans.

Disorders of the Skin

Pinworms (Oxyuris equi) are a common cause of tail rubbing in horses and are small white worms with a pointed tail that resembles a pin. Adult pinworms are found in the colon; the female worm migrates down the gastrointestinal tract and deposits eggs around the anus.

Biological Control in Tomato Production Systems

The tomato pinworm Tuta absoluta (Meyrick) is a devastating pest of tomato. This insect originated in South America, and has spread to several European, Middle Eastern, and North African countries since its discovery in Spain in 2006 ( Desneux et al., 2010 ). Recently, it was reported from India as well ( Kumari et al., 2015 ). T.

Overview

Morphology

The adult female has a sharply pointed posterior end, is 8 to 13 mm long, and 0.5 mm thick. The adult male is considerably smaller, measuring 2 to 5 mm long and 0.2 mm thick, and has a curved posterior end. The eggs are translucent and have a surface that adheres to objects. The eggs measure 50 to 60 μm by 20 to 30 μm, and have a thick shell flattened on one side. The small size and colourl…

Classification

The pinworm (genus Enterobius) is a type of roundworm (nematode), and three species of pinworm have been identified with certainty. Humans are hosts only to Enterobius vermicularis (formerly Oxyurias vermicularis). Chimpanzees are host to Enterobius anthropopitheci, which is morphologically distinguishable from the human pinworm. Hugot (1983) claims another species affects humans, Enterobius gregorii, which is supposedly a sister species of E. vermicularis, and …

Life cycle

The entire life cycle, from egg to adult, takes place in the human gastrointestinal tract of a single host, from about 2–4 weeks or about 4–8 weeks. E. vermicularis molts four times; the first two within the egg before hatching and two before becoming adult worm.
Although infection often occurs via ingestion of embryonated eggs by inadequa…

Infection

E. vermicularis causes the medical condition enterobiasis, whose primary symptom is itching in the anal area.

Distribution

The pinworm has a worldwide distribution, and is the most common helminth (i.e., parasitic worm) infection in the United States, western Europe, and Oceania. In the United States, a study by the Center of Disease Control reported an overall incidence rate of 11.4% among children. Pinworms are particularly common in children, with prevalence rates in this age group having been reported as high as 61% in India, 50% in England, 39% in Thailand, 37% in Sweden, and 29% in Denmark.
