BACKGROUND Avian influenza (AI) caused by H7 AI viruses (AIVs) of both low pathogenicity (LP) and high pathogenicity (HP) are notifiable poultry diseases. OBJECTIVES Design and validate two RealTime reverse transcriptase polymerase chain reactions (RRT PCRs) for Eurasian H7 AIV detection and pathotyping. METHODS The H7 RRT PCRs amplified within the (i) HA2 and (ii) cleavage site CS regions ...

ABSTRACT
 Background/aim: Early in the COVID-19 pandemic, chest computerized tomography (CCT) was shown to be more sensitive than real-time reverse transcription polymerase chain Reaction (rRT-PCR) detecting disease, especially regions with high disease prevalence. In this study, we aimed determine sensitivity and specificity of CT diagnosis COVID-19.
 Materials methods: Between 17 Ma...

During 2010-2011, Real-time PCR procedure was used to detecting FMDV RNA on 147 epithelium samples from the field. In this survey, for Real-time PCR from 3D gene segment as conserve region selected for tracking all of seven serotypes FMDV. The assay detected the viral RNA in all serotypes of FMDV. The rRT-PCR specifically detected FMD virus in sample with greater sensitivity than our convention...

during 2010-2011, real-time pcr procedure was used to detecting fmdv rna on 147 epithelium samples from the field. in this survey, for real-time pcr from 3d gene segment as conserve region selected for tracking all of seven serotypes fmdv. the assay detected the viral rna in all serotypes of fmdv. the rrt-pcr specifically detected fmd virus in sample with greater sensitivity than our convention...

during 2009-10, real time rt-pcr and conventional rt-pcr techniques used for detecting btvs rna in 310 blood samples. for real time and gel based rt-pcr segment-1 and segment-10 selected as conserve genes to search any btv strains. using these methods, 58 (%18.7) and 14 (%4.5) positive samples were detected among the clinically suspected sheep. sensitivity of both molecular techniques evalua...
