Dog's disease echinococcosis contagious to humans: scientists

09-26-2010 08:55 BJT

LA PAZ, Sept. 24 (Xinhua) -- Bolivian and Uruguayan scientists had found a dog's disease, echinococcosis, was also contagious to human beings, Freddy Lizon, director of the research team, said Friday.

The echinococcosis is caused by echinococcus granulosus parasites. It can causes cysts in vital organs.

"The dog is the carrier. If the parasite is defecated and eaten by sheep, and if humans eat the sheep, they will get a cyst," Lizon said.

"The cysts appear in the liver and there are different levels of symptoms according to the cyst degree. They can cause digestive problems, bile colic and diarrhea. Mainly we found the disease in poor areas, so perhaps it could be connected with malnutrition," Lizon said.

The research was carried out in Bolivia's Potosi region.
