چکیده
INTRODUCTION: This study aimed to develop a duplex endpoint PCR assay for rapid detection and differentiation of Leptospira strains. METHODS: Primers were designed to target the rrs (LG1/LG2) and ligB (LP1/LP2) genes to confirm the presence of the Leptospira genus and the pathogenic species, respectively. RESULTS: The assay showed 100% specificity against 17 Leptospira strains with a limit of detection of 23.1pg/µl of leptospiral DNA and sensitivity of 103 leptospires/ml in both spiked urine and water. CONCLUSIONS: Our duplex endpoint PCR assay is suitable for rapid early detection of Leptospira with high sensitivity and specificity.

Marek’s disease (MD) is a lymphoproliferative disease of chickens characterized by lymphocyticinfiltration of various organs. The present study was an attempt to use polymerase chain reaction (PCR) tooptimize a rapid and reliable assay for detection of MDV genome. Detection of serotype 1 of MDV (MDV-1)was confirmed by presence of a 200 bp DNA fragment as a PCR product. Differentiation of MDV-1 ...
