Glanders, although known to be endemic in certain regions/countries of the Old and New Worlds for centuries, had been largely overlooked as a threat to equine and human health until the disease re-emerged in the Middle East in 2004. The exponential growth in international horse movements, both legal and illegal, mainly for performance purposes, has enhanced the risk of global spread of glanders in the Middle East and elsewhere. Ever since the First World War, the glanders bacillus has been recognised as a potential biological warfare agent.
