Mitigating such disease threats is challenging, partly because uncertainty about disease dynamics makes it difficult to identify the best management approaches. Serious impacts on susceptible populations most frequently occur when generalist pathogens are maintained within populations of abundant (often domestic) ‘‘reservoir’’ hosts, and spill over into less abundant host species. If this is the case, disease control directed at the reservoir host might be most appropriate. However, pathogen transmission within threatened host populations may also be important, and may not be controllable by managing another host species. Methodology/Principal Findings: We investigated interspecific and intraspecific transmission routes, by comparing African wild dogs’ exposure to six canine pathogens with behavioural measures of their opportunities for contact with domestic
