“…For example, subtype C has a global distribution, but only two subtypes have ever been found in North America, AMPV-C and the newly identified and yet unclassified subtype [15,18]. AMPV RNA has been identified in various wild birds, such as ducks, geese, gulls, starlings, and others [15,18,19,20,21,22].…”

Wild birds are recognized viral reservoirs but our understanding about avian viral diversity is limited. We describe here three novel RNA viruses that we identified in oropharyngeal/cloacal swabs collected from wild birds. The complete genome of a novel gull metapneumovirus (GuMPV B29) was determined. Phylogenetic analyses indicated that this virus could represent a novel avian metapneumovirus (AMPV) sub-group, intermediate between AMPV-C and the subgroup of the other AMPVs. This virus was detected in an American herring (1/24, 4.2%) and great black-backed (4/26, 15.4%) gulls. A novel gull coronavirus (GuCoV B29) was detected in great black-backed (3/26, 11.5%) and American herring (2/24, 8.3%) gulls. Phylogenetic analyses of GuCoV B29 suggested that this virus could represent a novel species within the genus Gammacoronavirus, close to other recently identified potential novel avian coronaviral species. One GuMPV–GuCoV co-infection was detected. A novel duck calicivirus (DuCV-2 B6) was identified in mallards (2/5, 40%) and American black ducks (7/26, 26.9%). This virus, of which we identified two different types, was fully sequenced and was genetically closest to other caliciviruses identified in Anatidae, but more distant to other caliciviruses from birds in the genus Anas. These discoveries increase our knowledge about avian virus diversity and host distributions.

“…The glycoprotein attachment (G) gene sequence was the most frequently targeted (Cha et al., 2013 ; Curland et al., 2018 ; Delogu et al., 2004 ; Felippe et al., 2011 ), followed by the matrix (M) gene sequence (Bennett et al., 2004 ; Jardine et al., 2018 ; Turpin et al., 2008 ). Lastly, the nucleoprotein (N) gene (Rizotto et al., 2019 ) and the large polymerase (L) gene sequences were, respectively, targeted once (van Boheemen et al., 2012 ), whereas Heffels‐Redmann et al. ( 1998 ) did not specify the gene used for PCR analysis.…”

“…Viral isolation was attempted in five out of 11 studies through inoculation of chicken embryo fibroblast cultures (Bennett et al., 2004 ; Turpin et al., 2008 ), chicken embryonated specific pathogen free (SPF) eggs (Rizotto et al., 2019 ) or chicken embryo tracheal organ cultures (Heffels‐Redmann et al., 1998 ).

“…( 2018 ) in Canada where aMPV infection has never been reported for poultry. Considering South America, aMPV subtypes A and B were detected in numerous free‐living wild species and in individuals hosted in rehabilitation centres (Felippe et al., 2011 ; Rizotto et al., 2019 ), probably implying aMPV spread between the birds sampled in captivity. Concerning Europe, viral subtype C was molecularly detected in wild mallards ( A. platyrhynchos ), graylag geese ( Anser anser ( linnaeus, 1758 )) and common gulls ( Larus canus linnaeus, 1758 ) sampled in the Netherlands (van Boheemen et al., 2012 ) and in wild anatids sampled in Italy (Graziosi et al., 2022 ; Tucciarone et al., 2022 ).…”

Given the avian metapneumovirus (aMPV) disease burden in poultry worldwide and the evidence of a possible role played by wild birds in the virus epidemiology, the present study summarizes aMPV serological and molecular data on free‐ranging avifauna available in the literature by conducting a systematic review and meta‐analysis. A computerized literature research was performed on PubMed, Scopus, CAB Direct and Web of Science to identify relevant publications across the period 1990–2021, along with the screening of reference lists. A random‐effect model was applied to calculate pooled prevalence estimates with 95% confidence intervals. The inconsistency index statistic (I2) was applied to assess between‐study heterogeneity. Subgroup analyses for molecular studies only were performed according to geographical area of samplings, taxonomic order, genus and migration patterns of the birds surveyed. A total of 11 publications on molecular surveys and 6 on serological ones were retained for analysis. The pooled molecular prevalence was 6% (95% CI: 1–13%) and a high between‐study heterogeneity was detected (I2 = 96%, p < .01). Moderator analyses showed statistically significant differences according to geographical area studied, taxonomic order and genus. Concerning serological prevalence, a pooled estimate of 14% (95% CI: 1–39%), along with a high between‐study heterogeneity, was obtained (I2 = 98%, p < .01). Moderator analysis was not performed due to the scarcity of eligible serological studies included. Overall, molecular and serological evidence suggests that some wild bird taxa could play a role in aMPV epidemiology. Particularly, wild ducks, geese, gulls and pheasants, according to scientific contributions hereby considered, proved to be susceptible to aMPV, and due to host ecology, may act as a viral carrier or reservoir. Further surveys of wild birds are encouraged for a better comprehension of the poultry/wild bird interface in aMPV epidemiology and for better characterizing the virus host breadth.

Recent insights into the genetic and antigenic variability of avian metapneumovirus (aMPV), including the discovery of two new subtypes, have renewed interest in this virus. aMPV causes a well-known respiratory disease in poultry. Domestic species show different susceptibility to aMPV subtypes, whereas sporadic detections in wild birds have revealed links between epidemiology and migration routes. To explore the epidemiology of aMPV in wild species, a molecular survey was conducted on samples that were collected from wild birds during avian influenza surveillance activity in Italy. The samples were screened in pools by multiplex real time RT-PCR assays in order to detect and differentiate subtypes A, B, C, and those that have been newly identified. All the birds were negative, except for a mallard (Anas platyrhynchos) that was positive for aMPV subtype C (sampled in Padua, in the Veneto region, in 2018). The sequencing of partial M and full G genes placed the strain in an intermediate position between European and Chinese clusters. The absence of subtypes A and B supports the negligible role of wild birds, whereas subtype C detection follows previous serological and molecular identifications in Italy. Subtype C circulation in domestic and wild populations emphasizes the importance of molecular test development and adoption to allow the prompt detection of this likely emerging subtype.
