Abstract
BACKGROUND: Gammacoronaviruses, which are single-stranded, positive-sense RNA viruses, are responsible for a wide variety of existing and emerging diseases in birds. The Gammacoronaviruses primarily infect avian hosts. OBJECTIVES: This study aimed to investigate the genetic diversity of Gammacoronaviruses in quail population in Iran. METHODS: In the period from 2016 to 2018, samples from 47 quail flocks with or without enteric signs, were collected from four provinces in Iran. RESULTS: Gammacoronavirus was detected in samples of 4 flocks by using RT-PCR and characterized by N gene sequencing. The isolates formed a distinct group from other Gamma- coronaviruses groups. CONCLUSIONS: The finding suggests the existence of a novel Gammacoronavirus circulating in quail farms. The phylogenetic relationship of the isolates concerning different sequences and geographical regions displayed complexity and diversity. The present study is the first detection of Gammacoronavirus in quail farms in Iran. Further studies are required and should include the isolation and experimental studies of Gammacoronaviruses in Iran.
