“…JSPX03E showed a close relationship with SDFC12, which was isolated from ducks with BADS disease by other scholars. In the previous reports, DuCV and NGPV were found to be vertically transmitted respectively (Chen, Tang, Dou, Zheng, & Diao, 2016;Li et al, 2014). This study firstly confirmed the possibility of simultaneous vertical transmission of DuCV and NGPV in individual embryos.…”

“…The duplex PCR assay with high specificity and sensitivity was established for simultaneous detection of mixed infection of the two genotypes of DuCVs in our previous study (Li et al., ). The primers DuCV‐F (CGG GAA ATG ACG TAG TCG TCA TG, position 640–662) and DuCV‐R (GGA(C) C(T)TG(A) AAC ATG AGA TGG GC, position 1653–1672) were designed for DuCV‐1 and DuCV‐2, and DuCV‐1F (GTT CAC TCC G(T)GT TGT GTT GTC C(T)GG, position 1226–1249) and DuCV‐2R (GAT AAT GCG ACC(T) GGC GAC G, position 1219–1239) were designed for genotype DuCV‐1 and DuCV‐2, respectively (Li et al., ).…”

As a newly emerged infectious disease, duck "beak atrophy and dwarfism syndrome (BADS)" disease has caused huge economic losses to waterfowl industry in China since 2015. Novel goose parvovirus-related virus (NGPV) is believed the main pathogen of BADS disease; however, BADS is rarely reproduced by infecting ducks with NGPV alone. As avian circovirus infection causes clinical symptoms similar to BADS, duck circovirus (DuCV) is suspected the minor pathogen of BADS disease. In this study, an investigation was carried out to determine the coinfection of NGPV and DuCV in duck embryos and in ducks with BADS disease. According to our study, the coinfection of emerging NGPV and DuCV was prevalent in East China (Shandong, Jiangsu and Anhui province) and could be vertical transmitted, indicating their cooperative roles in duck BADS disease.

Risk to public and/or animal health of the treatment of dead‐in‐shell chicks (Category 2 material) to be used as raw material for the production of biogas or compost with Category 3 approved method

In 2011, EFSA assessed the risk posed by the possible use of dead‐in‐shell chicks for the production of processed pet food. In 2014, the European Commission asked for an update on the risk posed by the same material but as raw material for the production of biogas and compost according to standard transformation parameters normally used for Category 3 material. According to current European Union legislation, the following processing method was considered: maximum particle size before entering the processing unit: 12 mm; minimum temperature in all material in the unit: 70°C; and minimum time in the unit without interruption: 60 minutes. A list of pathogens potentially present in the material to be treated was compiled and available literature data were used to assess the ability of the processing methods to inactivate the most resistant pathogens identified. Spores of Clostridium botulinum were identified as the most resistant hazard potentially present in the material to be processed. Circovirus and parvovirus and Enterococcus faecium were considered the most heat‐resistant viruses and non‐sporulating bacterium, respectively. Moreover, depending on storage conditions, the formation of bacterial toxins is possible. The processing methods considered were therefore assessed for their ability to inactivate those hazards. The probability of survival of pathogens related to the use of dead‐in‐shell chicks subjected to the treatment process was considered to be extremely low for the heat‐sensitive pathogens that could be present in the material, which include bacteria such as Salmonella and avian influenza virus. However, this treatment is unable to sufficiently inactivate other relevant hazards (e.g. bacterial spores, thermoresistant viruses and certain bacterial toxins).
