Paratuberculosis is a chronic disease in ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). Most economic losses due to MAP occur in the dairy industry. However, the infection is not restricted to cattle, but also occurs in other ruminants, such as sheep, goat, and deer. Although deer are of minimal economic importance in The Netherlands, they may constitute a source of infection for the dairy industry. This pilot study was conducted to estimate the prevalence of Johne's disease in farmed red deer in The Netherlands. Serum and faecal samples were collected from 140 animals, originating from 8 different farms. Four of the farms had animals that tested positive for Johne's disease. The within-herd MAP seroprevalence varied between 4.8% and 21.2%. In conclusion, this pilot study provides evidence of MAP infection in the Dutch farmed deer population, and thus there might be a risk of MAP transmission between farmed red deer and dairy cattle.
副结核病是由鸟分枝杆菌副结核亚种（MAP）引起的反刍动物慢性疾病。MAP造成的大部分经济损失发生在乳制品行业。然而，这种感染并不局限于牛，也发生在其他反刍动物身上，如绵羊、山羊和鹿。尽管鹿在荷兰的经济重要性很低，但它们可能是乳制品行业的感染源。本试点研究旨在估计荷兰养殖马鹿中约翰氏病的患病率。从来自8个不同农场的140只动物身上采集了血清和粪便样本。其中4个农场的动物约翰氏病检测呈阳性。牛群内MAP血清阳性率在4.8%至21.2%之间。总之，本试点研究提供了荷兰养殖鹿群中MAP感染的证据，因此养殖马鹿和奶牛之间可能存在MAP传播的风险。
