Summary: A total of 142 clinically healthy cattle in five herds were examined serologically and for persistant infection with Savine Viral Diarrhea Virus (SVDV) in Konya. Leucocyte and blood sera samples were obtained from the ani­ mals. BVDV antigens were determined in total of iwo animals in iwo herds alter examination by immunoflour esans test (IFT) of the 142 leucocyte samples. Second leucocyte samples were obtained from 2 callle two months alter the initial sampling and SVDV antigens were not detected. The 142 first blood sera samples were tested against SVDV by sera neutralisation (SN) test. Antibodies to SVDV were detected in 113 (%79. 5) of 142 samples. Although viremic cattle and high seropositivity were found in two herds, persistant infe cted (Pl) cattle couldn't be detected in this study.
