副猪嗜血杆菌血清5型分离株生长曲线与致病力研究

本文对副猪嗜血杆菌血清5型生长曲线进行了研究。结果表明：种子液接种后6 h开始进入对数生长期,培养24 h后活菌数达到最高峰,20～30 h活菌数维持在同一个水平,进入稳定期,30 h后活菌数呈现下降趋势,进入衰退期。该曲线提供了副猪嗜血杆菌生长规律,为疫苗研制提供了理论基础。...

In this paper,the growth curve of Haemophilus parasuis serotype 5 strain was studied.The result showed that the growth of Haemophilus parasuis serotype 5 strain went in the logarithmic growth phase after 6 hours post-inoculation（hpi）, and reached the peak after 24 h,and then remained at the same level afer 20-30 h,which indicated that the bacteria entered the stable phase.After 30 h, the bacteria showed a downward trend,meaning going into the recession phase.The establishment of the growth curve supplied a better understanding of the growth characteristics of Haemophilu
