“…The higher prevalence of γ-CoVs in the US of 4.99% is consistent with findings from some previous studies. In a screening study from Brazil, quail were susceptible to both δ- and γ-CoV [20]. The higher prevalence of γ-versus-δ-CoVs and variations in preferred avian host species have been also reported by other researchers in other countries, such as Australia [6], Asia (Hong Kong and Cambodia) [11] and Finland [14].…”

“…Environmental sampling of high-risk and co-mingling sites in Alberta and Saskatchewan Canada, identified δ-CoV in sparrows, that are closer phylogenetically to porcine δ-CoVs than to those from waterfowl [19]. To date, the presence of δ-CoV is confirmed in sparrows in Canada and the US [13], in quail in Brazil [20] and in various birds in Australia [6], suggesting that δ-CoVs circulate in different avian species in the Americas. Since porcine δ-CoV often results in severe clinical disease and mortality in piglets, which impacts the swine industry, it is important to understand the morbidity and interspecies transmission rates between birds and pigs [4,5].…”

Porcine deltacoronavirus (δ-CoV) is the object of extensive research in several countries including the United States. In contrast, the epidemiology of δ-CoVs in wild birds in the US is largely unknown. Our aim was to comparatively assess the prevalence of δ- and γ-CoVs in wild migratory terrestrial and aquatic birds in Arkansas, Illinois, Indiana, Maryland, Mississippi, Missouri, Ohio, Tennessee and Wisconsin. A total of 1236 cloacal/fecal swabs collected during the period 2015–2018 were tested for γ- and δ-CoVs using genus-specific reverse transcription-PCR assays. A total of 61 (4.99%) samples were γ-CoV positive, with up to 29 positive samples per state. In contrast, only 14 samples were positive for δ-CoV (1.14%) with only 1–4 originating from the same state. Thus, unlike previous reports from Asia, γ-CoVs are more prevalent than δ-CoVs in the US, suggesting that δ-CoVs may spread in birds with lower efficiency. This may indicate δ-CoV emerging status and incomplete adaptation to new host species limiting its spread. Phylogenetic analysis of the partial N gene revealed that the newly identified δ-CoV strains were most closely related to the HKU20 (wigeon) strain. Further studies are necessary to investigate the role of aquatic bird δ-CoVs in the epidemiology of δ-CoVs in swine and terrestrial birds.

“…The disease is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, further referred to as CoV-2), one of only seven known human coronaviruses, which belong to either alpha or beta coronaviruses (Coronaviridae Study Group of the International Committee on Taxonomy of, 2020; Gralinski and Menachery, 2020). Two other genera of coronaviruses, gamma and delta, do not comprise any members that affect human health and are mostly found in other mammals (mostly pigs) or avian species (Chu et al, 2011;Torres et al, 2016;Wang et al, 2014;Woo et al, 2012). Most of the human coronavirus infections are mild and are estimated to cause up to 15% of the common cold cases (Perlman and Netland, 2009).…”

“…Such modified virus could then spillover in the reverse direction back to a poultry population, and the possibility of its higher pathogenicity could not be ruled out (36). Recently, interesting results for the presence of both gamma- and deltacoronaviruses in quails were reported (39, 40, 41). The identified gammaCoVs revealed a similarity to IBV strains unique to South America (40).…”

Coronaviruses (CoVs) are a large group of enveloped viruses with a single-strand RNA genome, which continuously circulate in mammals and birds and pose a threat to livestock, companion animals, and humans. CoVs harboured by avian species are classified to the genera gamma- and deltacoronaviruses. Within the gamma-CoVs the main representative is avian coronavirus, a taxonomic name which includes the highly contagious infectious bronchitis viruses (IBVs) in chickens and similar viruses infecting other domestic birds such as turkeys, guinea fowls, or quails. Additionally, IBVs have been detected in healthy wild birds, demonstrating that they may act as the vector between domestic and free-living birds. Moreover, CoVs other than IBVs, are identified in wild birds, which suggests that wild birds play a key role in the epidemiology of other gammaCoVs and deltaCoVs. Development of molecular techniques has significantly improved knowledge of the prevalence of CoVs in avian species. The methods adopted in monitoring studies of CoVs in different avian species are mainly based on detection of conservative regions within the viral replicase, nucleocapsid genes, and 3’UTR or 5’UTR. The purpose of this review is to summarise recent discoveries in the areas of epidemiology and diagnosis of CoVs in avian species and to understand the role of wild birds in the virus distribution.
