There are a huge number of parasites that a person can become infected with. The likelihood of infection depends on living conditions and lifestyle. Each type of parasite is distinguished by its structural features, appearance, and the process of vital activity.
In some cases, they do not provoke the development of any symptoms, and a person can only see them in their feces. Most parasites live inside the body, and although we do not see them, it is important to know how worms look in humans.
What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>
What pinworms look like
Appearance | Life cycle |
Pinworms are spindle-shaped. They differ in white. Females reach a length of 25 cm, males - 15. You can see the parasite in the feces. Usually males are dead and do not move. |
After entering the body, the larvae ripen within 15 days. The habitat of the parasite is the intestine. The males die after mating, while the female lays eggs around the anus. During this process, severe itching occurs, and the person involuntarily combs this place, thereby spreading the eggs onto bedding and household items. The female is capable of laying over 20 thousand eggs per day, which mature within 6 hours. |
What a whipworm looks like
This worm is distinguished by a white, sometimes gray or reddish tint, a thin hair-like shape. The front part is elongated, the back is thick, but shorter than the front. In the back are the internal organs of the parasite. Males are distinguished by a tail rounded in a spiral; in females, it has the shape of a curved arc.
Vlasoglava reaches a length of about 5 cm. It is almost impossible to distinguish between a female and a male in size. The eggs are yellowish, golden, or brown. They are barrel-shaped with four layers of the shell. The parasite penetrates the mucous membrane and feeds on blood, which provokes the development of anemia.

What roundworms look like
They belong to the group of roundworms affecting the digestive system. There are a large number of roundworm varieties, they are capable of infecting not only humans, but also various animals. In humans, only one type of worm is parasitized - Ascaris lumbricoides.
This type of worm has a round shape. Females can grow up to 40 cm, males up to 25 cm. The body thickness usually reaches 5 mm. They usually settle in the intestine and can live in it for 2 years. The parasite is pink in color. Females have a tapered tail. In males, the body is bent towards the abdominal cavity.
Due to the lack of special hooks, the parasite is unable to attach to the intestinal walls. Eggs and dead worms are excreted during bowel movements. Ascaris larvae can migrate throughout the body, affecting any organ.

Trichinella appearance
It is a representative of the nematode group. The body has a round, slightly elongated shape, tapering at one end. An adult reaches a size of 4 mm. The larvae of the parasite are very small, it is extremely difficult to see them without special equipment. When the larvae penetrate into the muscles, they increase, grow to 0.7 mm, and acquire a spiral shape.
Unlike other roundworm species, Trichinella spp. Do not lay eggs in the intestines. After mating, the female bears eggs inside herself. Then, with its front end, it bites into the walls of the intestine and throws out the larvae (up to 2000) into it.
This process allows the larvae to enter the bloodstream, and spread throughout the body, provoking the development of various pathological conditions.
The larvae are capable of living for a long period, about 20 years, in the striated muscles. A capsule is created around them, the structure of nearby tissues is destroyed. The larva can stay in this state all its life until it is swallowed by another host.
What do tapeworms look like in humans
This type of parasite is characterized by a flat, long shape, divided into segments. In the front part of the parasite there are tentacles, in the neck and back there are segments.
Each segment of the worm has a uterus that allows the formation of eggs. The severed segment is excreted with feces into the external environment. Thus, the reproduction of the parasite occurs. Chains are considered the most common types of these worms.
Type of helminth | Description |
Pork tapeworm |
This parasite can be contracted by eating poorly processed pork. |
Bovine tapeworm |
A large individual that grows up to 40 meters. The intermediate host is cattle. If the larvae of the parasite infect the liver, heart, the risk of death is extremely high. |
Wide ribbon |
Infection occurs when eating raw or poorly processed fish. |
Dwarf chain |
They grow no more than 7 cm. Invasion occurs upon contact with contaminated household items, such as toys. |
Echinococcus |
It is considered the most dangerous species. It infects the lungs with the liver, the invasion is asymptomatic, so the parasite can be detected in the later stages of the disease. The parasite is carried by sick animals. Only surgical methods of therapy are suitable for treatment. |
What do dead worms look like in feces in humans
With helminthic invasion, dead and living individuals can be found in the feces. They differ little from each other. Living worms are easier to see, they will move, the dead are motionless. In some cases, the color of the dead specimen will differ from the color of the living one. They can take on a dark shade. It is very difficult to see the eggs of worms in the feces without a microscope.
No one is immune from infection with helminths. You can reduce the likelihood of infection by observing preventive measures. If negative symptoms appear, it is better to consult a doctor for diagnosis and selection of effective drug treatment. Knowing what parasites look like, you can protect yourself from advanced forms of infestation.
