“…Indeed, the experimental infection of SPF turkeys by the intranasal route with duck APV-C isolates was followed by an APV-C-specific seroconversion, which demonstrates that duck APV-C isolates are indeed infectious for turkeys [24]. The converse experiments have also demonstrated that US APV-C isolates from turkeys are infectious for ducks [25,26]. Altogether, the present study reveals a greater heterogeneity than expected among the G genes of subgroup C APVs and calls for further study of the epidemiological significance of these genetic lineages, both in the United States and in Europe.…”

The gene encoding the attachment glycoprotein (G) was sequenced in three French isolates of-subgroup C avian metapneumovirus (APV-C) from ducks. With 1771 nt, this gene proved as long as recently published for North-American APV-C isolates from turkeys. The nt sequences of the duck viruses shared 99% identity but proved only 75-83% identical with their North-American counterparts, viruses of both origins encoding 585 amino acid (aa)-long G proteins. Alignments revealed more homogeneity within the European and North-American groups (at least 98 and 79% aa identity, respectively) than between European and North-American viruses (at best 70% a identity), and confirmed the presence of an extracellular divergent domain (positions 302-484) in APV-C G. A phylogenetic analysis demonstrated that North-American and French isolates of APV-C belonged to significantly different genetic lineages, in agreement with the different geographical origin and host species of these viruses.

“…Current methods used to detect aMPV subtype C infections, such as virus isolation, positive RT-PCR and detection of aMPV-C-specific antibodies, have demonstrated infection in several wild bird species, including rock pigeons, Canadian geese, blue-winged teals, swallows, house sparrows, ring-billed gulls, Muscovy, Pekin ducks, mallards and ostriches Shin et al, 2000Shin et al, , 2001Bennett et al, 2002Bennett et al, , 2004Turpin et al, 2003Turpin et al, , 2008. Thus, studies involving other aMPV subtypes, especially subtype C, in the Brazilian wild bird population are still needed.…”

“…In support of this, aMPV-C antibodies or viral RNA were detected in many wild avian species, including American coots, American crows, Canada geese, cattle egrets, rock pigeons, blue-winged teal, wild geese, wild ducks and mallard ducks (Shin et al, 2000Bennett et al, 2002Bennett et al, , 2004Bennett et al, , 2005Turpin et al, 2008;Velayudhan et al, 2008;Padhi & Poss, 2009). The ability of aMPV-C viruses to infect and replicate in ducks has also been reported, suggesting that isolates from poultry can infect this avian species (Shin et al, 2001). In Brazil, where only subtypes A and B have been detected, the role of wild and synanthropic birds in the epidemiology of SHS is not yet clear, nor is it known whether the aMPV A and B subtypes can be isolated from these avian species.…”

Detection of and phylogenetic studies with avian metapneumovirus recovered from feral pigeons and wild birds in Brazil

The aim of the present study was to determine whether avian metapneumovirus (aMPV)-related viruses were present in wild and synanthropic birds in Brazil. Therefore, we analysed samples from wild birds, feral pigeons and domestic chickens in order to perform a phylogenetic comparison. To detect the presence of aMPV, a nested reverse transcriptase-polymerase chain reaction was performed with the aim of amplifying a fragment of 270 bases for subtype A and 330 bases for subtype B, comprising the gene coding the G glycoprotein. Positive samples for aMPV subtypes A and B were found in seven (13.2%) different asymptomatic wild birds and pigeons (50%) that had been received at the Bosque dos Jequitibás Zoo Triage Center, Brazil. Also analysed were positive samples from 15 (12.9%) domestic chickens with swollen head syndrome from several regions of Brazil. The positive samples from wild birds, pigeons and domestic chickens clustered in two major phylogenetic groups: some with aMPV subtype A and others with subtype B. The similarity of the G fragment nucleotide sequence of aMPV isolated from chickens and synanthropic and wild avian species ranged from 100 to 97.5% (from 100 to 92.5% for the amino acids). Some positive aMPV samples, which were obtained from wild birds classified in the Orders Psittaciformes, Anseriformes and Craciformes, clustered with subtype A, and others from the Anas and Dendrocygma genera (Anseriformes Order) with subtype B. The understanding of the epizootiology of aMPV is very important, especially if this involves the participation of non-domestic bird species, which would add complexity to their control on farms and to implementation of vaccination programmes for aMPV.

“…aMPVs cause an acute upper respiratory disease characterized by coughing, nasal discharge, tracheal rales, foamy conjunctivitis, and sinusitis that have been reported principally in turkeys; but cases have been identified in chickens, ducks, pheasants, and guinea fowl (3,7,9,21). The first cases were described in turkeys in South Africa in 1978, and the causative agent was isolated and identified as a pneumovirus in 1986 in Europe (4,14,17).…”

“…Much of the research in the United States has focused on turkey and wild birds, while little attention has been focused on farm-raised ducks and geese. The presence of the virus in experimentally infected ducks and the recent isolation of aMPV from wild geese demonstrate that these birds may also harbor the virus (21,22). A quick and inexpensive test is needed to determine the infection status of domestic geese and ducks.…”

Development and Evaluation of a Blocking Enzyme-Linked Immunosorbent Assay for Detection of Avian Metapneumovirus Type C-Specific Antibodies in Multiple Domestic Avian Species

The first cases of infection caused by avian metapneumoviruses (aMPVs) were described in turkeys with respiratory disease in South Africa during 1978. The causative agent was isolated and identified as a pneumovirus in 1986. aMPVs have been detected in domestic nonpoultry species in Europe, but tests for the detection of these viruses are not available in the United States. To begin to understand the potential role of domestic ducks and geese and wild waterfowl in the epidemiology of aMPV, we have developed and evaluated a blocking enzyme-linked immunosorbent assay (bELISA) for the detection of aMPV type C (aMPV-C)-specific antibodies. This assay method overcomes the species-specific platform of indirect ELISAs to allow detection of aMPV-C-specific antibodies from potentially any avian species. The bELISA was initially tested with experimental turkey serum samples, and the results were found to correlate with those of virus neutralization assays and indirect enzyme-linked immunosorbent assay (iELISA). One thousand serum samples from turkey flocks in Minnesota were evaluated by our bELISA, and the level of agreement of the results of the bELISA and those of the iELISA was 94.9%. In addition, we were able to show that the bELISA could detect aMPV-C-specific antibodies from experimentally infected ducks, indicating its usefulness for the screening of serum samples from multiple avian species. This is the first diagnostic assay for the detection of aMPV-C-specific antibodies from multiple avian species in the United States.

Susceptibility of ducks to avian pneumovirus of turkey origin

Abstract: Ducks inoculated with APV of turkey origin may not develop clinical signs of disease, but they are suspected to play a role as nonclinical carriers of APV.
