目的分析、报告安徽省首例人感染猪链球菌病例的实验室诊断结果,为该类实验检测提供依据。方法采用PCR试验方法对病人的血液标本进行猪链球菌2型特异性核酸片段的体外扩增。结果在病人血液标本中扩增出特异性目标核酸片段。结论在病原培养无法捡出病原菌,病人难以得到及时确珍的情况下,PCR实验检测特异性核酸片段是诊断人感染猪链球菌病的有效技术手段,具有极高的实用价值。 Objective To analyze and report the laboratory diagnosis results of the first case of human infection of Streptococcus suis in Anhui Province and provide the basis for the test of this kind of experiment. Methods PCR test was used to amplify type 2 specific DNA fragment of Streptococcus suis from patients’ blood samples. Results The specific target nucleic acid fragments were amplified in the blood samples of patients. Conclusion PCR detection of specific nucleic acid fragments is an effective technique to diagnose human infection with streptococcal disease, which is of high practical value.
