Echinococcosis is a zoonotic infectious disease. In echinococcosis, the circulation of the invasion (pathogen) is carried out by the following scheme:
Source of infestation (root / primary carrier) → environment contaminated with carnivorous dogs and eggs and parasitic worms → ie intermediate / medium carriers / vectors (farm animals, humans). The human is the intermediate / medium carrier biological closure.
Dogs become infected when they feed on larvae-infected organs / organs of farm animals. Echinococcus elongated, adult worms lay their eggs in the intestines of wolves and dogs. The eggs are then excreted in the feces. The mode of transmission of media (animals, humans) is also diverse, farm animals infect eggs, helminth organs / parts when ingested with green grass, dried grass, water, as well as through the feces of pests infested by pests.
And the remnants of eggs and echinococcal chains on human hair, fur and tail are damaged when dogs are nested or clinging.
Symptoms: In humans, there is varying degrees of pain, weakness, decreased activity, fatigue, jaundice, and sometimes allergic reactions in the right chest, chest cavity (depending on the location of larvae / worms). The animals have no symptoms and no clinical signs.
Preventive measures:
- It is forbidden to feed dogs with products of slaughtered farm animals (damaged liver or lungs).
- Quarterly sterilization of domestic dogs and hunting of stray dogs.
- Strict adherence to the rules of personal hygiene for dogs.
Treatment:
Treatment of people is usually more difficult and, accordingly, more complicated: surgical treatment, drug therapy, deworming of dogs with disinfectants (deworming). Treatment of farm animals is not economically viable.
