Viruses were isolated in cell culture (cc) (PAMs or MARC-145 cells) or in bioassays (ba). Day 7 samples were serum samples and were assayed only on MARC-145 cells. Day 56 and day 84 samples were tonsil biopsy and serum samples. Day 150 was the time of necropsy (tonsil, bronchial lymph node, lung, and serum samples). +, positive; −, negative; ND, not done.
