Human danger of the fish Anisacidosis

Anisacidosis is one of the most common and invasive diseases of humans. The cause of this disease is the larval stage of helminths belonging to the Anisacidae family. Human anisacidosis is caused by the use of marine fish invaded by helmintine larvae in nutrition in raw or not fully cooked, slightly salted, as well as in less acidic form.

Anizacidosis was firstly noted in human beings in the Netherlands in 1955. More than 300 anisacidosis patients were registered In Scandinavia countries in 1967. This disease is frequently recorded in countries where raw fish are used as a food (in Korea, China and Japan). In recent times, the nutrition in North American countries and France has become increasingly popular with the anisacidosis of humans in these areas. Also, many Anisacidosis patients have officially been recorded in Vladivastok, Russia. This is due to the fact that people use a little salty seafood cooked at home.

Symptoms of the disease give anisacid larvae for 10 days after eating, and is marked by severe pain in the gastrointestinal tract. The anisacids will cause abscesses and glands (inflammatory nodules) in the walls of the gastrointestinal tract. The larvae of this nematode were removed from the stomach wall through endoscopic or operative patients. In some cases, the infection is very high, and the disease results in death.

Taking into account the increase in the number of anisacid infections, the employees of the Parasitology Laboratory of the Institute of Zoology of ANAS have learned that there are anisacids fish in the Caspian Sea.

Anisacid larvae are found in many species of fish in the Caspian Sea. The last owners of the anisacids, which are parasitic in fish, are marine mammals and suites in the Caspian Sea. The most commonly used commodity was herbaceous herpes, often used by the population as food. During intense invasion, fish can be a source of illness, losing market appearance. The larvae of this nematode are mentioned in the hasham, shamai, hazelnut, zucchini herring, hazelnut shrub, zerf, naha, honey fishes. This nematode infection is even mentioned in the Stroke. Medium (up to 60 mm) larvae of this parasite are mainly found in the muscles of the abdomen of the fish, the side line, and rarely in the back muscles. In the fish they are in the form of a flat spiral ball. In the development of anisacids, as well as other nematodes of marine animals, several intermediate owners, including fishes, are also involved. Crustaceans play an important role in infecting anisacids in fish. When the anisacid larvae in the body of the fish move from the walls of the stomach to the body cavity and muscles, the size increases. Anisacid larvae are frost-resistant to -18 ºC and are destroyed at temperatures down to -20 ºC for 4-5 days, and -30 ºC to 10 minutes later. These parasites were tolerated up to +45 ºC but were destroyed at + 60 ° C for 10 minutes. Thus, the smoke from 45 to 60 ºC does not guarantee the destruction of the Anisacids.
