Distribution of artisanal cheese samples in four different dairy basin in Minas Gerais state. (A) Map of Brazil highlighting where Minas Gerais state and Belo Horizonte city are located; (B) All samples were collected in Belo Horizonte city, in the central area of Minas Gerais; (C) An example of artisanal cheese produced in Minas Gerais state; (D) Nucleotide sequence of the VACV detected in commercial artisanal cheese samples (blue) C11R (viral growth factor) gene compared with homologous sequences of several other orthopoxviruses. The amplified fragments were sequenced in both orientations by the dideoxy method in an ABI3130 platform (Applied Biosystems, Foster City, CA, USA), and sequence quality was analyzed by using Sequence Scanner Software 1.0 (Applied Biosystems, Foster City, CA, USA). Sequences were aligned (ClustalW (http://www.genome.jp/tools/clustalw). Information regarding chesse samples processing has been included as Supplementary Material.
