我们利用免疫金银染色／相差显微镜（IGSS／RCM）检测了113份牛尿标体，阳性10份，阳性率8．9％，较培养阴性率（5．3％）为高。与培养相比，阳性符合率85.7％，阴性符合率96．2％，IGSS／RCM10份阳性标本半定量计数．牛尿中所含构体大概数量从100条／ml到5200条／ml不等。这些均表明，IGSS／RCM是一种比较灵敏、特异和快速的方法，可用于传染源追踪和构体病早期诊断。也说明，耕牛是我国某些地区构体病的主要传染源之一。
We detected 113 samples of bovine urine by immunogold-silver staining / phase contrast microscope (IGSS / RCM). The positive rate was 8.9%, which was higher than the negative rate of culture (5.3%). Compared with the culture, the positive coincidence rate of 85.7%, the negative coincidence rate of 96.2%, IGSS / RCM10 positive specimens semi-quantitative count. Approximately the number of structures contained in cow urine from 100 / ml to 5200 / ml range. All of these show that IGSS / RCM is a sensitive, specific and rapid method for the tracking of infectious agents and the early diagnosis of structural diseases. It also shows that cattle farming is one of the main sources of structural diseases in some areas of our country.
