A nested PCR assay to detect parasite DNA in slit aspirates from skin lesions of patients with post-kala-azar dermal lesihmaniasis (PKDL) is described. PCR results were positive in 27 of 29 (93%) samples by nested PCR assay, while only 20 of 29 (69%) were positive in a primary PCR assay. The nested PCR assay allowed reliable diagnosis of PKDL in a noninvasive manner.
本文描述了一种巢式PCR检测方法,用于检测黑热病后皮肤利什曼病(PKDL)患者皮肤病变刮片中的寄生虫DNA。通过巢式PCR检测,29份样本中有27份(93%)结果呈阳性,而在初次PCR检测中,29份样本中只有20份(69%)呈阳性。巢式PCR检测能够以非侵入性方式对PKDL进行可靠诊断。
