采用酶联免疫吸附（ELISA）技术对花生青枯菌（Pseudomonassolanacearum）潜伏侵染进行检测，检测灵敏度为104菌／ml，对潜伏侵染的检测可准确到组织水平，样品制备可用缓冲液浸泡代替研磨，样品保存时间不影响检测效果。
Enzyme-linked immunosorbent assay (ELISA) was used to detect latent infection of Pseudomonas solanacearum. The detection sensitivity was 104 bacteria / ml. The detection of latent infection was accurate to the tissue level. The sample preparation could be replaced by buffer solution Grinding, sample storage time does not affect the test results.
