This report presents the results of surveillance on transmissible spongiform encephalopathies (TSE) in cattle, sheep, goats, cervids and other species, and genotyping in sheep, carried out in 2019 by 28 Member States (MS), and by Iceland, Montenegro, North Macedonia, Norway, Serbia and Switzerland (non-MS). In total, 1,150,388 cattle were tested by MS, a 2.7% decrease from 2018 and 44,557 by the six non-MS. Six cases of H-BSE were reported by France (4) and Spain (2), and 1 L-BSE by Poland. The number of H- BSE cases was the largest reported per year including the youngest ever case (5.5 years of age). In total, 338,098 sheep and 143,529 goats were tested in the EU, an increase of 3.9% in both species compared with 2018. In sheep, 17 inconclusive cases by two MS and 997 cases of scrapie were reported: 911 classical (97 index cases (IC), one of ARR/ARR genotype and 98.7% with genotypes of susceptible groups) by seven MS, 86 atypical (AS) (80 IC) by 11 MS. Thirty-one ovine scrapie cases were reported by Iceland and Norway. Random genotyping was only reported by eight MS: Cyprus excluded, 15.7% of genotyped sheep carried genotypes of susceptible groups. In goats, three inconclusive cases by two MS and 390 cases of scrapie were reported: 379 classical (24 IC) by six MS, 11 atypical (10 IC) by six MS. The heterogeneous enforcement of a 3-year surveillance programme for chronic wasting disease (CWD) in six MS (Estonia, Finland, Latvia, Lithuania, Poland and Sweden) resulted in the testing of 7,980 cervids and confirmation of three CWD cases in wild moose in Sweden. Other seven MS tested 2,732 cervids with no positive results. Norway tested 30,147 cervids in 2019, with two new moose cases. In total, 122 animals from four other species reported by three MS TSE tested negative.
本报告展示了2019年28个成员国以及冰岛、黑山、北马其顿、挪威、塞尔维亚和瑞士(非成员国)对牛、羊、山羊、鹿及其他物种进行的传染性海绵状脑病(TSE)监测结果,以及在绵羊中进行的基因分型结果。成员国共检测了1,150,388头牛,比2018年减少了2.7%,六个非成员国检测了44,557头。法国(4例)和西班牙(2例)报告了6例H型疯牛病,波兰报告了1例L型疯牛病。H型疯牛病病例数是历年报告中最多的,包括有史以来最年轻的病例(5.5岁)。欧盟共检测了338,098只绵羊和143,529只山羊,与2018年相比,这两个物种的检测数量均增加了3.9%。在绵羊中,两个成员国报告了17例不确定病例,997例羊瘙痒病病例:七个成员国报告了911例经典型(97例索引病例(IC),其中1例为ARR/ARR基因型,98.7%为易感群体基因型),11个成员国报告了86例非典型型(AS)(80例IC)。冰岛和挪威报告了31例绵羊瘙痒病病例。只有八个成员国报告了随机基因分型情况:不包括塞浦路斯,15.7%的基因分型绵羊携带易感群体基因型。在山羊中,两个成员国报告了3例不确定病例,390例羊瘙痒病病例:六个成员国报告了379例经典型(24例IC),六个成员国报告了11例非典型型(10例IC)。六个成员国(爱沙尼亚、芬兰、拉脱维亚、立陶宛、波兰和瑞典)对慢性消耗病(CWD)的三年监测计划执行情况不一,共检测了7,980头鹿,确认瑞典的野生驼鹿中有3例CWD病例。其他七个成员国检测了2,732头鹿,未得到阳性结果。挪威在2019年检测了30,147头鹿,发现了2例新驼鹿病例。三个成员国报告的其他四个物种的122只动物TSE检测呈阴性。
