最近的研究表明，獾可能是西班牙北部牛感染牛分枝杆菌的潜在宿主。这项研究的目的是调查牛和獾之间潜在的流行病学联系。从2008年至2012年全国结核病根除行动中扑杀的牛，以及同期捕获和检查的171只身体獾和60只活动物的培养和分子分型数据。从14只(8.2%)身体獾的混合组织中分离出结核分枝杆菌复合菌，其中II株被鉴定为牛分枝杆菌：随后鉴定出6种不同的牛分枝杆菌亚型。在牛和獾共享这些分离物的两个地理位置，受感染的牛群和獾生活在密切接触中。虽然目前尚不清楚獾在这种情况下是牛分枝杆菌的维持宿主还是溢出宿主，但采取预防措施以减少牛和獾之间的接触似乎是谨慎的。(C)2013爱思唯尔有限公司。保留所有权利。
Recent studies suggest that badgers may be a potential reservoir of Mycobacterium bovis infection for cattle in Northern Spain. The objective of this study was to investigate potential epidemiological links between cattle and badgers. Culture and molecular typing data were available for cattle culled during the national tuberculosis (TB) eradication campaigns between 2008 and 2012, as well as from 171 necropsied badgers and 60 live animals trapped and examined over the same time period.Mycobacterium tuberculosis complex strains were isolated from pooled tissues of 14 (8.2%) necropsied badgers, of which II were identified as M. bovis: six different spoligotypes of M. bovis were subsequently identified. In two geographical locations where these isolates were shared between cattle and badgers, infected cattle herds and badgers lived in close contact. Although it remains unclear if badgers are a maintenance or spill-over host of M. bovis in this setting, it would appear prudent to have precautionary measures in place to reduce contact between cattle and badgers.
