Hidatidosis

Granulosus is a disease produced by a called parasite Echinococcus and the definitive guests (they are those where the adult parasite stays itself) are the domestic dogs and some canine wild and live in the thin intestine, measure of 3 to 6 mm in length, (tapeworm) is ?a flat? parasite and its body has three segments and in the last it has several hundreds of eggs that are disintegrated in environment when it is eliminated with lees of the dog. Each egg contains an embryo which it must be ingested by an intermediary guest (he is that one where the youthful form of the parasite is developed) and are ovine, goat, bovine, pigs, equinos, camelidaes (Asian and American), cervids and the man.

The embryo frees itself in the thin intestine of the intermediary guests, crosses the intestinal wall and is taken by the sanguineous current to several organs, where esarrolla the larval stage, hidátide or hidatídico cyst. The most frequent location of these cysts is in liver and lungs, but sometimes it can be located in other organs (bones, kidney, brain, etc.). The interior of the cyst is full of liquid where prolight vesicles float (that are the infestante element) that the flame ?hidatídica river sand?. The cycle is completed when the dog or another canine one ingest vísceras with hidatídicos cysts that contain fertile cysts of an ovine or another intermediary guest.

In the man the rates of I infect more discharges are registered in cattle places, mainly in those of young of ovines. In essence one is a infestación of rural means, although also cases in urban areas happen. Many cysts are asintomáticos during all life., but in other cases the cyst can reach a very great size and to contain several liters of liquid, the great danger, sometimes with death risk, they are the breakage of the cysts that can cause an allergic reaction (anaphylactic shock), also exists a dissemination of the cyst with the formation of new and numerous hidatídicos cysts. Main sintomatologia is given by the pressure that exerts on the affected organs as it increases of size.

I infect in the man happens when the dog licks the anus and exist eggs in he himself, who by means of the language scatters by all his body, the man can be contaminated the hands when touching the animal.
The near contact with the animal and the deficient practices of personal hygiene is important factors in I infect of the dog the man.
Another source of important infection can be the contaminated vegetables and the water with eggs of the parasite.

Although the hidatidosis usually is a disease that affects the rural population, frequently happen urban cases of the disease when the dogs are fed by means of contaminated crude vísceras with eggs of the parasite.

Prevention
As control measures must be tried to interrupt the cycle of transmission in their more vulnerable point, that is to say, of the intermediary guest to the definitive guest.
In theory, this measurement would be very simple and would consist simply, in avoiding the access of the dogs to the vísceras of infected cattle. Nevertheless such measurement implies a high degree of conscience and responsibility in the rural settlers, difficult to reach in the socioeconómicas conditions of the countries developing.

Preventive measures:

• Not to feed the dogs with vísceras (?achuras?) crude.
• To worm to the puppies to the 15, 30, 45, 60, 75, 90 days of the birth and soon to repeat every 4 months.
• To make analysis of fecal matter in periodic form.
  
• To walk to the dog with necklace and strap, so that it does not wander.
  
• To wash the vegetables very well that are ingested crude.
• To avoid that the children take to earth or sand to the mouth.
• To wash the hands well after touching the dog.
• To avoid that the children are licked in the mouth by the dog.
• Rigorous of hygiene and taken care of measures.

Considering these suggestions and a little taken care of the possibility of infestación by he is practically very low, and as much adult as young they will be able to enjoy his mascot without no risk.
