Experimental infection of reindeer with bovine viral diarrhea virus
AbstractTwo 8-month reindeer (Rangifer tarandus) and a 1-month-old Hereford-Holstein calf (Bos taurus) were inoculated intranasally with the Singer (cytopathogenic) strain of bovine viral diarrhea (BVD) virus. Clinical signs in reindeer included loose stools containing blood and mucus, and transient laminitis or coronitis. Signs in the calf were limited to bloody mucus in the stool and lesions in the nasal mucosa. Antibody titers to BVD virus in the reindeer were intermittent, and titers in the calf persisted from days 14 to 63 post-inoculation (PI). Viremia was detected on PI day 4 in one reindeer, days 3-7 in the other, and days 2-7 in the calf. Bovine viral diarrhea virus was isolated from the lung of the calf at necropsy (PI day 63).
