First national model for bovine TB calls for more focus on cattle

The first national model to investigate the bovine TB spread has been developed by researchers in England. The results derived from the model demonstrated that the majority of herd outbreaks are caused by multiple transmissions routes -- including failed cattle infection tests, cattle movement and reinfection from environmental reservoirs (infected pastures and wildlife). The study suggests that improved testing, vaccination of cattle and culling all cattle on infected farms would be the most ef...
