To get an impression of the presence of pathogens in multi-aged flocks of old fancy chicken breeds in the Netherlands, plasma samples originating from 24 flocks were examined for antibodies against 17 chicken pathogens. These flocks were housed mainly in the centre and east of the Netherlands, regions with a high poultry density. The owners of the tested flocks showed their chicken at national and international poultry exhibitions. Antibodies against Avian Influenza, Egg Drop Syndrome '76 virus, Pox virus, Salmonella pullorum/gallinarum, Salmonella Enteritidis or Salmonella Typhimurium were not detected. However, antibodies against other Salmonella species, Mycoplasma gallisepticum, infectious bursal disease virus, infectious bronchitis virus, avian encephalomyelitis virus, chicken anaemia virus, infectious laryngotracheitis virus, and avian leukosis virus, subgroups A and B, and subgroup J were detected in a varying proportion of the flocks. This study shows that antibodies against many chicken pathogens are present among the flocks of old fancy chicken breeds that are exhibited at international poultry exhibitions.
为了解荷兰古老观赏鸡品种多龄鸡群中病原体的存在情况，对来自24个鸡群的血浆样本进行了检测，以查找针对17种鸡病原体的抗体。这些鸡群主要饲养在荷兰中部和东部，这些地区家禽密度较高。受试鸡群的主人会在国内和国际家禽展览会上展示他们的鸡。未检测到针对禽流感、1976年产蛋下降综合征病毒、痘病毒、鸡白痢/鸡伤寒沙门氏菌、肠炎沙门氏菌或鼠伤寒沙门氏菌的抗体。然而，在不同比例的鸡群中检测到了针对其他沙门氏菌、鸡毒支原体、传染性法氏囊病病毒、传染性支气管炎病毒、禽脑脊髓炎病毒、鸡贫血病毒、传染性喉气管炎病毒以及禽白血病病毒A、B亚群和J亚群的抗体。这项研究表明，在国际家禽展览会上展示的古老观赏鸡品种鸡群中存在针对多种鸡病原体的抗体。
