How do eggs of worms( helminths) look like in an adult and children in a photo, where do they lay, how many larvae live, can one see?
The problem of helminth infestation is still one of the most urgent for any person.There are a lot of ways to infect parasites, and it is difficult to detect them, especially at the initial stage of the disease, as these worms masquerade as the symptoms of a variety of diseases.That is why people who are wary of the onset of this scourge, often wonder about how the eggs of human worms look.To this question, any specialist will unambiguously answer that many of them can not be seen with the naked eye, they are so microscopic.See their shape and size( and they are completely different for each type of parasite), you can only in the photo.It's no secret that a lot of photos of not only sexually mature specimens of worms, but also their eggs, and larvae are laid out on the Internet.
Precisely because it is difficult to detect helminth infection in your body, you should consult a doctor if you suspect a possible infection.What kind of symptoms should serve as a trigger for this?Although they are sufficiently
- Disturbed sleep.Some types of worms lay eggs at night in the anus, causing unbearable itching and anxiety.Usually it is characteristic of children's pinworms;
- Constant constipation is caused by the fact that large worms curl up and close the intestinal passage, creating obstruction to stool;
- Constant diarrhea is associated with the fact that some parasites produce substances that dilute stools;
- Irritability in a person infected with helminths is due to the fact that the products of their vital activity irritate the nervous system.
The fact that eggs of human helminths have turned into sexually mature, reproductive individuals can also be indicated by such non-specific symptoms as joint and muscle pain due to migration of larvae along the body, allergic reactions, problem skin and hair caused by productsThe vital activity of parasites, anemia, the development of which is provoked by worms that feed on blood.
Worm eggs in children
Small children always become the main victim of helminths.There is nothing surprising.Kids spend most of their time on the street, do not hesitate to climb into puddles, play in sandboxes, often put their dirty hands in their mouths.The child's simplest hygiene requirements are often alien.And besides, in young children the protective barriers of the digestive tract are still imperfect, and the acidity of the gastric juice has been reduced to a certain age.That is why babies become a laricious extraction of parasites, in their organisms eggs and larvae of worms survive, turn into sexually mature individuals and cause irreparable harm.
A crumb can catch eggs of parasites anywhere: in the kindergarten, where there are probably worm-infested children, interacting closely with pets, digging for a walk in the ground and picking up various objects from it, houses with street shoes and not enough cleanly washed floors in the hallway.The likelihood of infection increases significantly if the child is not accustomed to observe the simplest rules of personal hygiene and consumes unwashed vegetables and fruits.According to statistical data, 8 out of 10 babies are invaded by eggs of worms among preschool children, but only one in three appears to be symptomatic of infection.
Due to the fact that the prevalence of infestations is very high, and the severity of clinical manifestations is almost absent, helminths in children are not perceived as a serious problem.But at the same time, parasites that have settled in the baby's body, provoke the development of allergies, lead to general exhaustion and sometimes can cause severe damage to internal organs.What kind of symptomatology will arise, directly depends on what eggs the worms have infected the baby.The following attributes are common to all helminthiases:
- Tearfulness and irritability of crumbs;
- Increased fatigue;
- With a good appetite, insufficient weight gain;
- Frequent cutaneous and allergic reactions;
- Constant pain in the abdomen.
In the event that an invasion of the eggs of worm-ascaris, neurological disorders and severe internal injuries develop.With pinworms, the main sign is the calculus in the anus, and girls often develop vulvovaginitis.
What does the worm's egg look like in a child?This question is of concern to many young parents who carefully follow the excrement of their children.Any specialist will reply to him that no matter how hard they try, they are not possible to see with the naked eye.This is only possible for laboratory technicians who have microscopes.This is due to the fact that they have very small dimensions.
There is another question that also interests many.It is often asked about how the worms lay eggs.It depends on the type of helminth that has settled in the human intestine:
- Pinworms, one of the most common parasites in humans, reproduce at night, crawling for this in the anus.In the folds of the anus these worms lay their eggs;
- Ascarids, which live in the small intestine, are deposited in it, after which they are taken out with the calves masses and within 2 weeks ripen under favorable conditions in the external environment;
- In tapeworms, the process of reproduction takes place a little differently.These long worms have a body divided into segments, each of which has its own reproductive system.In the very last segment of the worm, fertilization takes place, it breaks away and, together with the mature eggs, comes out, where it enters the intermediate host organism.
If, in the case of pinworms, self-infection is most likely, as they deposit their progeny in the anus and when combing the itching areas, a person can again swallow the parasite larvae adhering to the hands, then ascariasis only occurs when the rules of personal hygiene are not observed.The use of unwashed vegetables and fruits, on which there are eggs of worms, also leads to invasion.Belt helminths appear in humans due to insufficient culinary processing of meat and fish.
How many live eggs of worms?
This question is of concern to many patients, especially the parents of babies, most often prone to infection.Live in an environment without an intermediate host can mainly eggs helminth nematodes, therefore, this type of worm should be considered more:
- Most often people of any age are prone to infection with pinworms that cause enterobiasis.In the eggs of worms caught in the external environment, under favorable conditions, the larvae begin to ripen.This requires about a week of time and an optimum temperature of 23 to 40 ° C.But a slight reduction in the temperature regime is not dangerous for them.So at 18 ° С they can live 2 - 3 weeks, and at 5 - 10 ° С up to a month.After the larvae of the worms fully mature in the eggs, they become dangerous to humans;
- Eggs of worms of waxy heads causing trichocephalosis, after getting stuck in the soil, live and mature in it for 1-2 months;
- In ascaris, the viability period under favorable conditions can be stretched for several years.
How do eggs of human worms look like?
The way the progeny of worms looks like, many are interested in trying to independently detect the presence of helminths.Immediately it should be said that it is impossible to see them with the naked eye.Often, parents trying to determine if a kid has helminths after finding black spots in his feces panic.But there is no reason for alarm here, most likely these are the remains of unquenched complementary foods.It is easy to remember if the kiwi was given the day before( the seeds of this fruit are not digested and have a black color).
The same reaction can be caused by poppy seeds.But black eggs of worms in nature simply do not exist, for the most part they are transparent or light yellow.And to discern them independently is not possible.Identify them and in appearance and say which helminth occupied the intestine, can only an experienced laboratory technician, using for this microscopic method of research.That is why, with the slightest suspicion of invasion, it is necessary to hand in feces for analysis, and not to try to understand independently the presence or absence of infection by worms.
How do helminth eggs look in the feces, you can see in the photos from under the microscope with a strong increase, which are in sufficient quantity posted on the Internet.There you can read their description, as well as the cycles of development of parasites and ways of infecting them.Consider the most common types of parasites:
- Eggs of worm-ascaris come in 2 types - fertilized and unfertilized.Both of them look roughly the same, oval, less roundish and dark yellow.The shell is multilayered and thick, looking tuberous.The only difference between them is that the embryonic cell is clearly visible in the fertilized;
- The barrel-shaped barrel-shaped form with plug-like structures at the poles.The skin is yellowish-brown, smooth and thick;
- In helminth worms, eggs look asymmetrically under the microscope.They are oval-elongated and convex only on one side.The shell is transparent, completely colorless, thin and smooth;
- Eggs of tapeworms, broadly oval and round, differ in magnitude.They are much larger than other parasites and contain the oncosphere, which is equipped with 3 pairs of hooks and is surrounded by 2 transparent shells.Between them are developing filaments - filaments.
