Triquinosis

The triquinosis or trichinellosis is a parasitic disease produced by a ?worm? called Trichinella spiralis, which enquista in muscles of those domestic and wild animals that feed themselves with infested crude meat, being the pig the most affected when it is fed with undone on crude food or in the rubbish dumps (the larva stays up to four months in meat putrefacta alive), also the presence of rats in the small farms where pigs grow up are transmitting of the disease, meat of another pig destined to seizure by Trichinellosis - this can happen in a plant of task of pigs with a deficient control of the destiny of the seizures.
Also dogs and cats when ingesting can infect themselves meat infested with larvae of Trichinella spiralis.

Once ingested the parasitado food, by action of the gastric juice, one digests the meat and the capsules that surround the larvae, which grow quickly and in 2 or 3 days they arrive at the stage of adults, differentiated sexually.
In the thin intestine the copula takes place (the ova are fertilized in the uterus) after as the males are eliminated the outside whereas the females settle down in the mucosa of the intestine of the guest and begins the larviposición that is the birth of great amount of larvae. This period lasts approximately 1 month, after which the adult females also are eliminated the outside. A great amount is born of larvae by adult female (it has been considered in 1.400), many from which are expelled to the outside, but an important amount of them crosses the mucosa of the intestine and by lymphatic route or blood they are transported to all the body and they invade different organs, to end up being located in fluted muscles (voluntary), although all the muscles are not invaded with the same concentration of larvae: thus, the diaphragm they follow to him in sequence of greater degree of parasitación, the muscles of the base of the language, soon the maseteros, abdominal and intercostal and soon the rest (this detail of the different distribution from the larvae in the musculatura of the guest is of great importance for the diagnoses in the different derivatives from the pig); after 2 weeks approximately, already they present/display the characteristic winding.

Although in the pig, more of the times, the infestación happens inadvertent without no apparent manifestation of disease, including the animal it can have an optimal state for the task and soon in the Veterinary inspection of the meat a discreet or high muscular parasitación is verified. By such reason, a gordito? and apparently healthy pig ?does not give the security to be free of triPeruvian bark.

It is a zoonosis, in the human beings the disease is pronounced with three phases: Intestinal, migration and convalecencia.

* Intestinal: vomits, abdominal pain, diarreas, anorexy.
* Migration: edema palpebral, mialgias, fever, migraines.
* Convalecencia: mialgias, eosinofilia, leucocitosis.
