Indirect enzyme-linked immunosorbent assay (ELISA) and Reverse transcription-polymerase chain reaction (RT-PCR) were performed for determination of viral genotypes, including BVDV1, BVDV2, and HOBi like among PI samples.
Results: A total of 102371 samples were collected from 76 industrial dairies in Tehran and Alborz province, that 512 cases were PI. All samples were positive for BVDV1 (100%). Other genotypes were not found among PI samples.
