Reconstruction of Transmission events in a <i>K. pneumoniae</i> outbreak.

<p>Outbreaker (<b>A</b>) and SCOTTI (<b>B</b> and <b>C</b>) provide different interpretations of the <i>K. pneumoniae</i> outbreak. <b>A)</b> “Beanbag” tree of transmission events inferred with Outbreaker. Each circle represents a host, with “PMK” removed from their name. The number on transmission arrows represents the inferred posterior probability of the event. All arrows represent direct transmissions (without intermediate non-sampled hosts, with more than 85% support) except the one from PMK9 to PMK10 which is inferred to be through at least one intermediate host. <b>B)</b> “Beanbag” tree of transmission events inferred with SCOTTI. Numbers on arrows represent the inferred posterior probabilities of the corresponding direct transmission events. Colour intensity is proportional to posterior support. <b>C)</b> “Maypole” maximum clade credibility tree (see Fig A in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005130#pcbi.1005130.s001" target="_blank">S1 Text</a>) inferred with SCOTTI, annotated and coloured with the highest posterior probability hosts for internal nodes. “NS” represents all non-sampled hosts. Branch width indicates the posterior probability of the inferred host at the node at the right end of the considered branch. Branches are annotated with 95% posterior intervals of the number of transmissions. For non-annotated branches, the interval is [0, 1].
