The primary underlying cause of cervical cancer is infection with one or more high-risk (HR) types of the human papilloma virus (HPV). Detection and typing of HPV have been commonly carried out by PCR-based assays, where HPV detection and typing are two separate procedures. Here, we present a multiplex PCR-based HPV typing assay that detects 20 HPV types (15 HR, 3 probably HR and 2 low risk) us...
زمینه و اهداف: سویه‌های سم‌زای(Toxogenic) ویبریوکلرا که واجد ژنهای ctxA،ctxB و zot هستند، نسبت به سویه‌های غیرسم‌زابیماری شدیدتری ایجاد می‌کنند، بنابراین شناسائی دقیق و سریع سویه‌های سم‌زا بسیار حائز اهمیت است. این مطالعه با هدف به‌کارگیری روش Multiplex PCR برای جداسازی همزمان ژنهای ctxA ، ctxB و zot در ویبریو کلرا ایزوله‌شده از بیماران طراحی گردید. مواد و روش کار: در این مطالعه 73 سویه بالی...
PCR has revolutionized the field of infectious disease diagnosis. To overcome the inherent disadvantage of cost and to improve the diagnostic capacity of the test, multiplex PCR, a variant of the test in which more than one target sequence is amplified using more than one pair of primers, has been developed. Multiplex PCRs to detect viral, bacterial, and/or other infectious agents in one reacti...
BACKGROUND/AIMS The diagnostic yield of fecal leukocyte and stool cultures is unsatisfactory in patients with acute diarrhea. This study was performed to evaluate the clinical significance of the fecal lactoferrin test and fecal multiplex polymerase chain reaction (PCR) in patients with acute diarrhea. METHODS Clinical parameters and laboratory findings, including fecal leukocytes, fecal lact...
Papaya ringspot virus (PRSV), Papaya leaf distortion mosaic virus (PLDMV), and Papaya mosaic virus (PapMV) produce similar symptoms in papaya. Each threatens commercial production of papaya on Hainan Island, China. In this study, a multiplex reverse transcription PCR assay was developed to detect simultaneously these three viruses by screening combinations of mixed primer pairs and optimizing t...
