The authors examined the protoescolicide effect of natrium chiorid salty solution, in vitro and in vivo using ovine livers and lungs. The infected organs were immersed in saltysolutions of 5,10 and 20% concentration during 24 hours. By the in vitro experiment, the protoescolices were kept viable in a total 66.68%, 43.10% and 43.30% when treated in a solution of 5.10 and 20%, respectively. The víscera infected with hydatic cyst were offered to 6 dogs. During necropsy 4 of the dogs were found infected whit Echinococcus. Rejection and pathologic lesions could not he related to the daily intake of these vísceras by the dogs. The treatment of vísceras by immersion in natrium chiorid salty solution under the described time and concentration conditions can not be used as a preventive method for equinococosis.
