This study aimed to evaluate the use of conventional polymerase chain reaction (cPCR) and real-time quantitative PCR (qPCR) in the diagnosis of human strongyloidiasis from stool samples in tropical areas. Stool samples were collected from individuals and were determined to be positive for Strongyloides stercoralis (group I), negative for S. stercoralis (group II) and positive for other enteroparasite species (group III). DNA specific to S. stercoralis was found in 76.7% of group I samples by cPCR and in 90% of group I samples by qPCR. The results show that molecular methods can be used as alternative tools for detecting S. stercoralis in human stool samples in tropical areas.
本研究旨在评估传统聚合酶链反应(cPCR)和实时定量聚合酶链反应(qPCR)在热带地区粪便样本诊断人体类圆线虫病中的应用。从个体采集粪便样本,并确定其粪类圆线虫呈阳性(第一组)、粪类圆线虫呈阴性(第二组)以及其他肠道寄生虫种类呈阳性(第三组)。通过cPCR在第一组样本的76.7%中检测到粪类圆线虫特异性DNA,通过qPCR在第一组样本的90%中检测到该DNA。结果表明,分子方法可作为热带地区人体粪便样本中检测粪类圆线虫的替代工具。
