On the view of the restricted knowledge on the diversity of coronaviruses in poultry other than chicken, this study aimed to investigate the molecular diversity of coronaviruses in quail, pheasant and partridge from two regions of Northern Italy. For these purpose, pools of tracheal and cloacal swabs from European quail (Coturnix coturnix), and intestinal tract of pheasants (Phasianus colchicus) and partridge (Perdix perdix) flocks, with or without enteric signs, were collected during 2015. An Avian coronavirus (Gammacoronavirus) was detected in quails not vaccinated against Infectious Bronchitis Virus (IBV) and pheasant vaccinated with an IBV Massachusetts serotype. Based on DNA sequences for the gene encoding the S protein, the avian coronaviruses detected in the quail and pheasant are related to the IBV 793B and Massachusetts types, respectively. However, RNA-dependent RNA polymerase (RdRp) analyses showed the susceptibility of quail also to Deltacoronaviruses, suggesting that quail and pheasant avian coronaviruses share spike genes identical to chicken IBV spike genes and quail might host Deltacoronavirus.

Abstract

On the view of the restricted knowledge on the diversity of coronaviruses in poultry other than chicken, this study aimed to investigate the molecular diversity of coronaviruses in quail, pheasant and partridge from two regions of Northern Italy. For these purpose, pools of tracheal and cloacal swabs from European quail (Coturnix coturnix), and intestinal tract of pheasants (Phasianus colchicus) and partridge (Perdix perdix) flocks, with or without enteric signs, were collected during 2015. An Avian coronavirus (Gammacoronavirus) was detected in quails not vaccinated against Infectious Bronchitis Virus (IBV) and pheasant vaccinated with an IBV Massachusetts serotype. Based on DNA sequences for the gene encoding the S protein, the avian coronaviruses detected in the quail and pheasant are related to the IBV 793B and Massachusetts types, respectively. However, RNA-dependent RNA polymerase (RdRp) analyses showed the susceptibility of quail also to Deltacoronaviruses, suggesting that quail and pheasant avian coronaviruses share spike genes identical to chicken IBV spike genes and quail might host Deltacoronavirus.
