| 中文摘要: |
| 来源不同地区的牛尿经聚合酶链反应（PCR）检测和分离培养，PCR产物凝胶电泳阳性率11%，PCR产物Southern－blot阳性率13%，分离培养阳性率3.1%。不同地区牛尿标本PCR检测结果差异明显。结果表明，我国某些地区的耕牛钩端螺旋体排菌率非常高，其中以七日热和澳洲群为主。说明耕牛是这些地区钩体病的主要传染源。PCR和培养分离结果的比较显示，PCR是构体病传染源调查的一种灵敏、特异、快速和简便的方法。 |
| 英文摘要: |
| Urine samples of Leptospires from cattle were detected by polymerase chain reaction (PCR)and isolation. Positive rates by Southern-blot and agarose gel electrophoresis of PCR amplification productions were 13% and 11% respectively. Positive rate of isolation was 3.1%. Various positive rates by PCR for cattle urine from different areas were discovered. Average rate of urihary excretion of Leptospires among cattle that naturally infected with Leptospira interrogans was 13.2%. Data showed that cattle was a major source of infection of Leptospirosis in some parts of China, According to the comparsion of results between PCR and isolation, we believe that PCR is a sensitive, rapid and simple method for the investigation on source of infection of Leptospirosis. |
