Genetic relationships between the sequence types of Pasteurella multocida identified in this study. Neighbour Joining phylogenetic tree based on concatenated sequences of 62 sequence types of P. multocida, showing main host association (blue = ovine isolates, purple = porcine isolates, yellow = avian isolates, green = bovine respiratory isolates, pink = bovine non-respiratory isolates and 2 elephant isolates, grey = no clear host association). Eleven groups, defined as isolates sharing 5 of 7 alleles, are shown.
