采集6月龄河南良杂猪的脾脏，分离淋巴细胞后直接提取总RNA，进行反转录－聚合酶链反应扩增，扩增产物进行T-A克隆、测序，获得了河南良杂猪IL-18基因成熟蛋白序列。

The peak of lesion sporulation appeared on the 27th day. The most suitable temperature for sporulating was 24℃. If relative humidity was lower than 88%, the lesion could not sporulate. Between 90% and 100%, the higher the RH was, the higher sporulation was. If continuous humidity time was lower than 5 h, the lesion could not sporulate. Between 7 h and 24 h, the longer it was, the higher sporulation was.
