Fig. 2

Phylogenetic relationship among isolates collected in different regions of Burkina Faso according to year. a CC181 NmX collected 2010–2012. b CC11 NmW isolates collected 2011–2012. Colored circles indicate the region of Burkina Faso in which the isolate was collected. Additional isolates are labeled with country and year of origin, except for isolates from Burkina Faso, which are indicated with a non-filled circle. The year of isolation is indicated by the position on the horizontal axis. The location of isolates from 2012 is marked at the bottom, and the range of years represented in the primary isolate collection is marked at the top. A dashed vertical line is included as a guide, indicating the location of 2012
