“…Quail coronavirus, which has a high spike sequence identity to TCoV, also causes enteritis with subsequent diarrhea and reduced growth in young quails (Coturmix coturmix) (Torres et al, 2013). In guinea fowl (Numida meleagris), guinea fowl coronavirus results in acute enteritis and pancreatitis (Liais et al, 2014). Other IBV(-like) coronaviruses cause respiratory and kidney diseases in pheasants (Phasianus colchicus) (Cavanagh, 2005;Gough et al, 1996), and respiratory disease and pancreatitis in pigeons (Columba livia; Qian et al, 2006).…”

“…3; Maurel et al, 2011), resulting in the creation of different serotypes (Jackwood et al, 2010). The genome of guinea fowl coronavirus aligns to the TCoV genome, suggesting a common ancestor, but a current separate evolutionary path (Liais et al, 2014). The S1 of quail coronavirus has ∼80% amino acid identity with certain TCoV strains, and only ∼17% aa identity with IBV.…”

Avian coronaviruses of the genus Gammacoronavirus are represented by infectious bronchitis virus (IBV), the coronavirus of chicken. IBV causes a highly contagious disease affecting the respiratory tract and, depending on the strain, other tissues including the reproductive and urogenital tract. The control of IBV in the field is hampered by the many different strains circulating worldwide and the limited protection across strains due to serotype diversity. This diversity is believed to be due to the amino acid variation in the S1 domain of the major viral attachment protein spike. In the last years, much effort has been undertaken to address the role of the avian coronavirus spike protein in the various steps of the virus' live cycle. Various models have successfully been developed to elucidate the contribution of the spike in binding of the virus to cells, entry of cell culture cells and organ explants, and the in vivo tropism and pathogenesis. This review will give an overview of the literature on avian coronavirus spike proteins with particular focus on our recent studies on binding of recombinant soluble spike protein to chicken tissues. With this, we aim to summarize the current understanding on the avian coronavirus spike's contribution to host and tissue predilections, pathogenesis, as well as its role in therapeutic and protective interventions.

“…Although its viral origin was previously suspected, virus remained unknown. Liais et al (2014) identified a novel avian gamma coronavirus associated with this disease which was distantly related to TCoVs. To decipher the RNA virus community from turkey flocks experiencing enteric disease, Day et al (2010) analyzed turkey gut RNA virus metagenomics and demonstrated the presence of turkey-origin members of the Picornavirales, and the genus Caliciviridae, and the turkey picobirnaviruses.…”

Summary. -Increased globalisation, climatic changes and wildlife-livestock interface led to emergence of novel viral pathogens or zoonoses that have become serious concern to avian, animal and human health. High biodiversity and bird migration facilitate spread of the pathogen and provide reservoirs for emerging infectious diseases. Current classical diagnostic methods designed to be virus-specific or aim to be limited to group of viral agents, hinder identifying of novel viruses or viral variants. Recently developed approaches of next-generation sequencing (NGS) provide culture-independent methods that are useful for understanding viral diversity and discovery of novel virus, thereby enabling a better diagnosis and disease control. This review discusses the different possible steps of a NGS study utilizing sequence-independent amplification, high-throughput sequencing and bioinformatics approaches to identify novel avian viruses and their diversity. NGS lead to the identification of a wide range of new viruses such as picobirnavirus, picornavirus, orthoreovirus and avian gamma coronavirus associated with fulminating disease in guinea fowl and is also used in describing viral diversity among avian species. The review also briefly discusses areas of viral-host interaction and disease associated causalities with newly identified avian viruses.
