country of origin, source of isolation, SNP and MLVA genotypes. The goat-derived strain (CbBEC1) has been isolated from an animal imported from the Netherlands. This strain has the same genetic profile as the CbNL01, the C. burnetii founder strain of the 2007–2010 Dutch outbreak episodes. SNP and MLVA profile of CbNL01 was derived from publicly available data.
