IMMUNOHISTOLOGY AS A RELIABLE AND EFFICIE NT - METHOD FOR THE DIAGNOSIS OF BVDV INFECTIONS

Persistent infection with the Bovine Viral. Diarrhea / Mucosal Disease Virus (BVDV) can be detected using immunohistological methods. The ex periments show that the LSAB (Labeled Streptavidin Biotin) peroxidase method is suitable to detect the BVDV in cryostat sections of unfixed tissue. For the diagnostic work up in living animals, skin biopsies gi ve reliable results. In dead animals, organs such as thyroid gland, sk in, mucosa of the mouth, esophagus and abomasum are well suitable for immunohistological BVDV detection.
