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.
在32、37和39摄氏度的温度下,对四种猪细小病毒分离株NADL-8、NADL-2、KBSH和Kresse在猪睾丸细胞中的复制情况进行了比较。Kresse分离株在32和37摄氏度时的复制受到限制,这从子代病毒、病毒多肽和病毒DNA合成方面得到了证实,但在39摄氏度时不受限制。相比之下,KBSH在39摄氏度时的复制受到限制,但在37或32摄氏度时不受限制。这项研究的结果支持了KBSH和Kresse分离株的复制依赖于温度这一论点。
