“…During the wild bird surveillance program for AI in Korea, a variety of haemagglutinating viruses were isolated and identified as AIV, APMV type 1, 4 and 6 and their prevalence was comparable to other reports Fujimoto et al, 2010;Hanson et al, 2005;Hinshaw et al, 1985;Hlinak et al, 2006;Shortridge et al, 1980;Stalknecht et al, 1991;Stanislawek et al, 2002;Tumova, 2003). In addition, there was evidence of co-infection found in 15 viruses in this study, which were reported in the other studies including coinfected isolates with different subtypes of AIVs (Sharp et al, 1997), with AIV and APMV type 1 (Dormitorio, 2009) , Table 3 However, there has been little information on the epidemio-logy of APMVs other than APMV type 1 in Korea.…”

“…Surveillance programs on different APMV serotypes have been conducted worldwide on poultry farms, wild populations or both (Alkhalaf, 2009;Maldonado et al, 1994;Maldonado et al, 1995;Stanislawek et al, 2002;Warke et al, 2008a;Zhang et al, 2007). These investigations have been directed at prevalence in order to understand the status of infection in wild birds and domestic flocks and to better understand the role of wild birds in spreading the viruses or infecting domestic birds with the viruses (Hinshaw et al, 2003).…”

Avian paramyxovirus (APMV) type 4 and 6 were isolated during an avian influenza (AI) surveillance program of wild birds. This study also conducted experimental infection of wild-bird-origin APMV type 4 and 6 in specific pathogen free (SPF) chickens to study pathogenicity and transmission within domestic flocks. In addition, serological prevalence data of APMV type 4 and 6 in domestic fowls was conducted with chicken sera collected from 2007 to 2009 in order to understand infection status. The results of the animal experiment showed that APMV type 4 and 6 had the ability to infect chickens with sero-conversion and to transmit the virus from infected birds to contacted birds, but showed low pathogenicity. Serological tests revealed that APMV type 4 was widespread in the poultry industry, especially in layer flocks, but the positive rate for APMV type 6 was very low. This study concluded that wild bird-origin APMV type 4 and 6 could infect the chickens by inter-species transmission and the seroprevalence of APMV type 4 was quite high in Korean poultry. However, since almost all the chicken flocks had a high level of antibody titer against APMV type 1, there was possibility of cross reaction between APMV type 1 and 4, which made the interpretations more complicated. In order to understand infection status in the natural environment, additional study is necessary regarding the seroprevalence of APMV type 4 and 6 in the wild bird population.(Key words : avian paramyxovirus type 4 and 6, experimental infection, inter-species transmission, seroprevalence, commercial chicken flocks) † To whom correspondence should be addressed : moip@cbu.ac.kr

“…It was observed the occurrence of serotype 4 (APMV-4) in free-living birds, such as duck (Alexander et al, 1979;Gough & Alexander, 1984;Stallknecht et al;Maldonado et al, 1995;Stanislawek et al, 2002;Jeon et al, 2008;Rosseel et al, 2011), goose and coot (Maldonado et al) and the serotype 5 (APMV-5) in parakeet, leading to depression, dyspnea, torticollis, vomiting, diarrhea and death (Mustaffabab Jee, 1974;Nerome et al, 1978;Gough et al, 1993).…”

SUMMARY:Diseases caused by avian paramyxovirus (APMV) occur in commercial, captive and wild birds worldwide, demonstrating the significant economic and ecological importance of these agents. Paramyxoviruses belong to the Paramyxoviridae family, Paramyxovirinae subfamily and Avulavirus genus. During the period 2000 to 2011, stool and small intestine samples of 1647 birds species were sent to the Laboratory of Electron Microscopy, Biological Institute of São Paulo, Brazil, for diagnosis of viral agents. The samples were processed by negative staining (rapid preparation) and resin embedding techniques. Under the transmission electron microscope by negative staining technique, in 294 (17.8%) samples of 1647 were visualized paramyxovirus particles pleomorphic, roughly spherical or filamentous, measuring 100 to 500 nm of diameter containing an envelope covered with spikes and characteristic helical herring-bone-like nucleocapsid measuring 15 to 20 nm in diameter. Ultrathin sections of the small intestine fragments revealed the presence of amorphous granular intracytoplasmic inclusions surrounded by membrane and containing viral nucleocapsid measuring 10-14 nm in diameter. Immature particles budding from cell membranes, pleomorphic, spherical and tubular particles containing viral nucleocapsid strands, and the complete particles measured up to 170 nm in diameter were seen in the cytoplasm. Intranuclear inclusions containing viral nucleocapsid were also visualized. Nuclei showed a marginalized chromatin.
