The 3 td was the nodular form and the 4 ln form was the mixed, the bacteriological examination, showed symptoms of edematous skin disease Corynebacterium pseudotuberculosis was isolated as a single infection. The phospholipase D toxin bands of the isolated pathogens were in a molecular size of 37 and 39 KDa. Serological investigation by using agar gel immunodiffusion test was strongly positive in serum samples. On the other hand, the OD reading of ELISA above the cut off point (0.28) was recorded in serum samples.
