Figures & data

Figure 1. The geographic locations of samples from farm and slaughtering environments. The triangular shades of blue represent the different farms of beef cattle, dairy cattle or sheep, and shades of red prismatic stand for different abattoirs of beef cattle, or sheep in major cattle and sheep producing areas in China. (A) Dairy cattle farm located in Changchun; (B) beef cattle farm located in Yitong; (C) beef cattle farm located in Dunhua; (D) beef cattle farm located in Zhenlai; (E) beef cattle farm located in Tongliao; (F) beef cattle farm located in Daqing; (G) dairy cattle farm located in Suihua; (H) dairy cattle farm located in Shenyang; (J) beef cattle farm located in Shaanxi; (K) beef cattle farm located in Xinjiang; (L) sheep farm located in Dunhua; (N) sheep farm located in Zhenlai; (O) beef cattle abattoir in Daqing; (P) beef cattle abattoir in Jixi; (Q) sheep abattoir in Zhenlai; (R) beef cattle abattoir in Siping; (S) beef cattle abattoir in Changchun; (T) beef cattle abattoir in Yanji.

Figure 2. The dendrogram generated by the ApaI enzyme-based pulsed-field gel electrophoresis patterns of the 34 representative L. monocytogenes strains was constructed. The corresponding data, including the name of the strain (Strain ID), PFGE types, serotype, MLST type, the type of sample, sampling date and district, are shown alongside the dendrogram to the right.

Figure 3. The minimum spanning tree of the seven STs of the 50 L. monocytogenes isolates obtained from ruminants in farm and slaughtering environments in China. The corresponding sequence type is displayed around the circles. The size of each circle corresponds to the isolate count, and the colour within these circles represent the type of region (A) or sample (B).
