“…By comparing our serological results with results from previous studies on other geese species, we found differences in the seroprevalence of IAV, AAvV-1, and EDSV between different species (Table 4). Native European migratory species, e.g., greater white-fronted goose (Anser albifrons), seem to be more exposed to IAV showing mean seroprevalence of 10.6% (Kruckenberg et al 2011) compared to neozootic resident species, such as Egyptian and Canadian geese (Branta canadensis) which show 6.1% and 2.8% seroprevalences, respectively (this study, Bönner et al 2003). Similar trends can be observed also in case of AAvV-1 (Table 4).…”

“…In line with this, AAvV-1 seroprevalence in greater white-fronted goose shows clear seasonal variation (Table 4). Molecular results from a previous study in Germany revealed a prevalence of 13.8% (4/29) for AAvV-1 in Canada geese during molt in autumn and of 1.6% (2/128) in white-fronted geese in winter (Kruckenberg et al 2011). Another RT-PCR-based study by (Fouchier et al 2003) reported a prevalence of 1.4% for IAV in wild geese (i.e., white-fronted, greylag (A. anser) and brent goose (Branta bernicla) ratio 20/1387) and of 2.6% in wild ducks (i.e., widgeon (Anas penelope), mallard (A. platyrhynchos), shoveler (A. clypeata), and teal (A. crecca) ratio 57/2232) on wintering grounds in northern Europe.…”

Aquatic birds can act as vectors and reservoir hosts for pathogens relevant for wild birds and poultry as well as human health. In this study, we address the questions (1) if the Egyptian goose (Alopochen aegyptiacus), as one of the most successful neozootic bird species in Europe, carry infectious agents that are relevant for poultry and wild birds and (2) if seasonal prevalences of these infectious agents differ from those of native geese species. In 2015 and 2016, up to 190 Egyptian geese from Western Germany were investigated serologically for antibodies (Ab) against influenza A viruses (IAV), Avian avulavirus 1 (AAvV-1), aviadenoviruses, Duck atadenovirus A (syn.: egg drop syndrome 1976 virus) (EDSV), and West Nile virus (WNV). Ab were detected against IAV in 6.1% (10/164), against AAvV-1 in 2.4% (4/165), against EDSV in 15.2% (16/105), and against aviadenoviruses in 0.86% (1/116) of the geese blood samples, respectively. None of the birds had Ab against WNV (0/84). PCR-based techniques (cloacal and/or pharyngeal swabs) were applied for the presence of IAV, AAvV-1, Mycoplasma spp., and Riemerella anatipestifer. Riemerella DNA was detected in the pharyngeal swabs with an overall prevalence of 70.3% (104/148). Neither Mycoplasma DNA nor IAV or AAvV-1 RNA could be detected in the pharynx or cloaca of the examined birds. Our study shows that Egyptian geese are frequent carriers of Riemerella anatipestifer and furthermore provides serological evidence of exposure to IAV, AAvV-1, and EDSV. It is one of very few studies on infectious agents of neozootic bird species. Comparing our results from a neozootic non-migratory goose species with published results from native migratory geese species (bean goose (Anser fabalis) and white-fronted goose (A. albifrons)) and another neozootic non-migratory goose species (Canada goose (Branta canadensis)), we found differences in the seroprevalence of viral pathogens. Native goose species show higher seroprevalences of IAV and AAvV-1, whereas neozootic non-migratory geese reveal higher seroprevalences for EDSV. The findings are discussed in the frame of seasonal variations in selected infectious agents, differences in sampling periods, and contrasting movement ecology of the different geese species.

“…1800 samples from Ukraine from all seasons (mute swan Cygnus olor , whooper swan Cygnus cygnus , greater white-fronted goose Anser albifrons , greylag goose Anser anser , and red-breasted goose Branta ruficollis ), but were able to isolate APMV-1 only in two greater white-fronted geese sampled in winter. German studies based on serology report either negative results (greylag goose [ 23 ]), 6–8% seroprevalence in breeding Canada geese Branta canadensis ,[ 24 ] 14% in Canada geese in fall,[ 25 ] and 45% in greater white-fronted geese in October.

“…As stated above, Newcastle disease is not of immediate human health concern, but the role of swans and geese as reservoir or spill-over hosts [ 21 , 30 ] and their potential to act as long-distance biological or mechanical vectors [ 22 , 25 , 31 ] of precursors to velogenic APMV-1 strains remains poorly understood, and warrants continued attention ( cf .

There are more herbivorous waterfowl (swans and geese) close to humans, livestock and poultry than ever before. This creates widespread conflict with agriculture and other human interests, but also debate about the role of swans and geese as potential vectors of disease of relevance for human and animal health. Using a One Health perspective, we provide the first comprehensive review of the scientific literature about the most relevant viral, bacterial, and unicellular pathogens occurring in wild geese and swans. Research thus far suggests that these birds may play a role in transmission of avian influenza virus, Salmonella, Campylobacter, and antibiotic resistance. On the other hand, at present there is no evidence that geese and swans play a role in transmission of Newcastle disease, duck plague, West Nile virus, Vibrio, Yersinia, Clostridium, Chlamydophila, and Borrelia. Finally, based on present knowledge it is not possible to say if geese and swans play a role in transmission of Escherichia coli, Pasteurella, Helicobacter, Brachyspira, Cryptosporidium, Giardia, and Microsporidia. This is largely due to changes in classification and taxonomy, rapid development of identification methods and lack of knowledge about host specificity. Previous research tends to overrate the role of geese and swans as disease vectors; we do not find any evidence that they are significant transmitters to humans or livestock of any of the pathogens considered in this review. Nevertheless, it is wise to keep poultry and livestock separated from small volume waters used by many wild waterfowl, but there is no need to discourage livestock grazing in nature reserves or pastures where geese and swans are present. Under some circumstances it is warranted to discourage swans and geese from using wastewater ponds, drinking water reservoirs, and public beaches. Intensified screening of swans and geese for AIV, West Nile virus and anatid herpesvirus is warranted.
