Sensitivity of Bovine Tuberculosis Surveillance in Wildlife in France: A Scenario Tree Approach

摘要: Bovine tuberculosis (bTB) is a common disease in cattle and wildlife, with an impact on animal human health, economic implications. Infected wild animals have been detected some European countries, bTB reservoirs wildlife identified, potentially hindering the eradication of from populations. However, surveillance involves several practical difficulties not currently covered by EU legislation. We report here first assessment sensitivity system for free-ranging launched France 2011 (the Sylvatub system), based scenario tree modelling. Three components were identified: (i) passive scanning hunted boar, red deer roe deer, carcass examination, (ii) found dead, moribund or abnormal behaviour, badger (iii) active boar badger. The application these three depends geographic risk infection which turn prevalence cattle. estimated effectiveness quantitatively, each species separately. Active examination approaches most likely to detect at least one infected population given design prevalence, regardless local level considered. awareness hunters, their training risk, was affect sensitivity. results obtained are relevant hunters veterinary authorities wishing determine actual efficacy as function area species, could provide support decision-making processes concerning enhancement strategies.
