DETECTION OF NOVEL PICORNAVIRUS IN BROILER FLOCKS ,IRAN, 2018 : THE FIRST REPORT

Background and Aim:Runting-stunting syndrome (RSS) in broiler chickens is an enteric disease that causes significant economic losses to poultry producers worldwide due to elevated feed conversion ratios, decreased body weight during growth, and excessive culling.Recent analyses of the enteric viromes in turkeys and chickens have revealed complex viral communities comprised of multiple viral families.Methods:We got 50 cecal samples from broiler flocks with RSS and after RNA extraction, we run RT-PCR for detection and amplification of the variable gene of picornaviruses. After sequencing, we draw phylogenetic tree based on the results.Results:The results confirmed the new picornavirus have been detected in the samples and 90 percent of samples are positive for the picornavirus.Conclusion:This is the first report on identification of Sicinivirus in commercial layer chickens with a severe clinical disease in Iran, however, further studies are needed to evaluate the pathogenic potential of this picornavirus in chickens.
