Parasites that infect humans pass through 3 stages of their development. The most dangerous and accompanied by a bright symptomatology, we can name the second, in which the worm hatched eggs begin to migrate through the body in search of a place of their further residence. They can show up in any internal organ, under the skin and even in the eyes. Symptoms in this case do not at all resemble invasion by helminths, that's why it is quite difficult to find out the obvious reason for the appearance of negative symptoms. Only a small part of the parasite remains to live in the intestine.
What do the worm larvae look like in the photo? This question interests many. But to see the parasites with the unaided eye there is no possibility, so they are microscopic. Consider them only possible in the photo, which are made with the help of a microscope. They do not look as horrendous as adult helminths, but harm often brings much more. Larval stages of the known to all and the most widespread worm from the class of nematodes - ascarids, localized in the body, affect lung and liver tissues, cause extensive allergic reactions. Numerous foci of hemorrhage in the internal organs, arising from their introduction, provoke the development of severe diseases, such as pneumonia and cirrhosis of the liver. The worm's larvae not only cause poisoning of the body with its toxic effect, but also cause such serious disorders as:
- Mechanical pressure on internal organs and rupture;
- Cell destruction in host tissues due to active movement( migration);
- Anemia, internal bleeding, metabolic disorders.
At the initial stage of colonization of worm larvae in an organism in an invasive patient, symptoms of such diseases as myocarditis, pneumonia, conjunctivitis, hepatitis can occur. It is very difficult to compare it with helminthiasis, and therefore often the patient is unsuccessfully treated for uncharacteristic manifestations, caused by the fact that the cells of the human body are intensively divided, trying to restore the parasite-damaged tissues. In order to identify the true cause of the disease, it is necessary to conduct a blood test for antigens to helminths, since the usual stool analysis in this case is not informative.
Larval helminthiases
This medical term means that the patient has been diagnosed with larval worm infestations that have afflicted one of the internal organs. In this case, people are only intermediate hosts, until the sexually mature stage, the parasite can not develop. Despite the fact that invasion by worms of worms takes a short time, it is very dangerous, and in case of non-detection causes irreversible disturbances of vital organs. The way the liver, heart or lungs, in which the parasites live, can be seen in photos located on specialized sites or in medical reference books. The most common in our country are the following larval worm infections:
- Cysticercosis. It is caused by a ribbon worm with a pork chain. This disease can affect the skin, eyes, lungs, heart, brain or spinal cord. In any of the organs where helminth larvae are localized, irreversible changes occur. Only correctly conducted diagnostics and timely adequate treatment will help the patient to avoid serious health problems, and sometimes even death. As the cycle of infection with this parasite looks, one can look at the attached image;
- Echinococcosis is caused by larvae of echinococcus. Eggs of the worm enter the body if the rules of personal hygiene are not respected, with the wool of domestic and wild animals. Most often, the lungs and the liver are affected, in which the cysts are formed.
Since the infection with extraintestinal helminthiasis most often occurs with the use of meat or fish that have undergone insufficient heat treatment, many are interested in the question of at what temperature the worm larvae die. The answers to this question can be met completely different, therefore in order to completely protect yourself against possible infection, you should turn to the opinion of specialists:
- When freezing -40 ° C, the worm larvae in meat or fish die after 3 hours. But it is not supported by any modern freezer, so we should focus on the optimum temperature for our freezers -18 ° C.With her helminths can be destroyed within a week;
- Safety will ensure long-term boiling and roasting of the product. In order to eliminate the worm larvae in meat, it takes at least 1.5 hours of heat treatment. For fish this time is reduced to 20-30 minutes. Also for fans of delicacies, one should keep in mind that it is possible to destroy worm larvae only with hot smoking method.
