Foot-and-mouth disease
The virus strain was identified on 4 August as FMDV BFS 1860 O1 1967 (Foot-and-mouth disease virus, British field strain 1860, serotype O, subtype 1, isolated in 1967; also referred to as strain BFS 1860/UK/67). The virus was first isolated during the 1967 foot-and-mouth outbreak and until the 2007 outbreak was not in circulation in animals. It was the same strain as used at the nearby Pirbright laboratory sites that housed separate units of the Institute for Animal Health (IAH) and Merial Animal Health Ltd at Pirbright, away.
