Summary:
A stable social structure may help control the spread of bovine tuberculosis (TB) among badgers, ecologists have found. The findings -- published online in the British Ecological Society's Journal of Animal Ecology -- have important implications for the role of badger culling as part of the strategy to control bovine TB in the UK.

A stable social structure may help control the spread of bovine tuberculosis (TB) among badgers, ecologists have found. The findings -- published online in the British Ecological Society's Journal of Animal Ecology -- have important implications for the role of badger culling as part of the strategy to control bovine TB in the UK.

According to the authors from the Central Science Laboratory and the Instituto de Investigación en Recursos Cinegético in Spain: "The evidence suggests that movement of individuals between groups may be instrumental in driving disease dynamics at the population level, and adds further support to the contention that the social disruption of badger populations, for example by culling, is likely to promote disease spread."

Data for the study came from an undisturbed high-density badger population in the Cotswolds, Gloucestershire, that has been intensively studied by ecologists for more than 15 years. The authors analysed almost 9,000 trapping records involving 1,859 different badgers between 1990 and 2004. Each time a badger was trapped it was sexed, weighed and samples of blood, sputum, urine and faeces were taken before it was released. They found that TB rates were lowest when there was the least movement of individual badgers between groups.

There have been few experimental studies of the incidence of infectious disease in socially-structured wildlife populations, and this study shows that such information is crucial to understanding how population structure affects the spread of disease.

The results also have major implications for future policy to control bovine TB in the UK. According to the authors: "Past badger culling policies have been accompanied by an inexorable rise in the incidence of TB in cattle. Indeed, it has become apparent that the various strategies may actually have been a contributory factor to the increase in disease through perturbation. The results presented in this paper lend weight to this argument."

"The development of successful strategies for the control of TB in badgers and transmission to cattle will require serious consideration of the likely impact of any interventions on badger social organization," the authors say.
