Temperature dependent replication of porcine parvovirus isolates.
The replication of four porcine parvovirus isolates, NADL-8, NADL-2, KBSH, and Kresse, in swine testes cells were compared at temperatures of 32, 37, and 39 degrees C. Replication of the Kresse isolate was restricted at 32 and 37 degrees C as evidenced by progeny virus, virus polypeptide and viral DNA synthesis, but not at 39 degrees C. In contrast, replication of KBSH was restricted at 39 degrees C, but not at 37 or 32 degrees C. Findings from this study support the contention that replication of KBSH and Kresse isolates are temperature dependent.
