Isolate relatedness in the 2009 outbreak. (a) Maximum likelihood tree of the core genome SNPs for the 29 isolates obtained from five chickens. A total of 30 core genome SNPs between these 29 isolates was identified. The tree is rooted from midpoint. Scale bar shows the number of SNPs. (b) Minimum spanning tree constructed from the total of 210 SNPs identified between the core genomes of the 29 isolates. Isolates with identical core genome: PM1336 and PM1347, PM1331 and PM1353, PM1344 and PM1348, PM1332 with PM1346 and PM1351. (c) Minimum spanning tree when isolates from bird one were compared to each other only.
