Often, the only definite sign that a person has worms is the presence of parasite eggs in the feces. All other signs, such as itching in the anus at night, allergic manifestations on the skin, weight loss, etc., can be symptoms of a wide variety of diseases. Often people do not know what the eggs of worms look like. This is not surprising, especially when you consider that their shape, size, color and other characteristics can differ significantly.

Most often, attempts to visually identify the eggs of worms are made by parents who suspect that their children are infected with worms. Sometimes, seeing strange inclusions in feces, adults think that it could be eggs. You can understand whether it is possible to detect them with a simple examination after you get acquainted with their descriptive characteristics. Photos and information available on the Internet come to the rescue.

Various types

Spores of many types fall under the concept of worm eggs. The fact is that human worms are called worms from a large detachment, parasitizing in the human body. Most of them are localized in the upper and middle parts of the intestine, often causing various digestive disorders. Sometimes such symptoms are perceived as a sign of pathologies of the gastrointestinal tract, but treatment does not work, since the true cause of the problem has not been established. In this case, a reliable diagnosis is the determination of the eggs of the worms in the feces.

Many patients believe that they can find eggs in their feces on their own, without even knowing what they look like. In order to avoid such mistakes, you should familiarize yourself in more detail with the information on the reproduction of worms.

Spores and cysts in feces can only be detected after the internal parasite reaches puberty. Worms are extremely fertile creatures, so they can lay several hundred thousand cysts per day. Such eggs are very resistant to external conditions, therefore, it is in this form that the animals spread and get into a new host. The eggs can remain viable for 4 to 6 weeks. Most spores and cysts end up in unfavorable conditions and die, and only a few of the entire clutch will eventually turn into a sexually mature worm. This circumstance has led to a very high fruitfulness.

They look like rounded or oval formations. In different species, they may be slightly flattened or elongated at the upper poles. Two or three layers of the shell are always found on the surface, designed to keep the inner contents from mechanical damage, drying out and other negative factors. These shells appear as transparent, whitish, yellowish, or grayish grains.

Pinworms

All pinworms are dioecious, and the mechanism of their reproduction is well studied by specialists. The mating process of male and female takes place in the upper intestine, where ideal conditions for the sexual process are present. After it, the female descends into the lower intestine, then leaves the anus and makes a clutch, which contains about 25 thousand spores. The female dies immediately after this.

Pinworm cysts appear as irregular ovals. The miniature dimensions do not allow them to be seen, since the diameter together with the shell does not exceed 0.04 mm. The shell is very dense, therefore, when viewed through a microscope, laboratory technicians can easily move eggs using special glass rods without risking damage to the structure. Thanks to the reliable shell, the larva retains the ability to develop even after being at a temperature of 5-10%. At normal temperatures, they remain alive for up to four weeks.

Ascaris

Ascaris, unlike pinworms, make clutches inside the intestines. The food masses carry with them these spores, appearing at 250 thousand pieces per day from one individual. Rounded spores measuring 0.07 mm in size look like oblong milky capsules. For detection, a person's feces are taken for analysis, which are examined in detail under a microscope.

Before getting into a permanent host, cysts are stored in water, soil, on animal hair, and after swallowing they develop into sexually mature individuals.

Bovine and pork tapeworm

Biohelminths, which are capable of parasitizing in the human body for 10-20 years, causing a significant deterioration in health. Infection occurs when eating foods that have not been thermally processed, since spores are unstable to heat.

After the parasite reaches puberty, several hundred thousand cysts mature in the segments of the body of the tapeworms. These segments break off and are removed along with the feces. The eggs are slightly elongated in shape, they have a grayish or yellowish color.

Chains hold the record for the viability of cysts: they remain capable of further development for seven months.

Toxocars

They are considered one of the most prolific worms, which can lay up to 250 thousand eggs per day. Compared to other species, these cysts are quite large - they reach 0.1 mm in length. Under the microscope, you can see small bumps on their surface, which help to accurately identify the parasite. The shell is strong enough, so that the cysts remain capable of further development for a month after leaving the human body.

Vlasoglav

The size and number of whipworm eggs depend on the condition of the parasite. Under good conditions, they grow up to 0.055 mm. Cysts look like small barrels of grayish or yellowish color. In order to open up inside the human body, the dispute must be ripe. Ripening occurs about 3-4 months in the soil. More often than others, preschool children are exposed to infection due to poor personal hygiene.

Even in the presence of worms, it is not always possible to find eggs in the feces. This is due to the cyclical reproduction of parasites. In order to obtain reliable results, microscopic analysis is carried out at least twice.
