Abstract
In a pasture located at Kyong Puk area, a group of 200 Korean native casttle showed severe coughing, dyspnea and emaciation, of which 30 cattle died from the respiratory disease. To the alived cattle, clinical, pathologicoparasitological observations and treatment with terramycin, Mintic and tetramisole (Bonasol) were carried out and the following results were obtained. 1) Paroxymal coughighings, increased respiratory rate and heart rate were observed in almost all cases. But, larval output in feces was recognized in 32 percent of the cases. 2) Morderate eosinophilia was observed in a half of the cases. 3) At autopsy, lungs were enlarged, and areas of dark consolidations were scattered in all lobes. In the bronchi, numerous adult lungworms were found. 4) The adult worms detected from the bronchi were morphologically identified as Dictyocaulus viviparus. 5) The clinical signs and larval output were disappeared after the administration of Mintic or Bonasol. 6) From these results, it was concluded that the respiratory disease of the cattle was caused by the infestation of lungworm, Dictyocaulus viviparus.
