SCOTTI: Efficient Reconstruction of Transmission within Outbreaks with the Structured Coalescent (original) (raw)
Fig 5
Reconstruction of transmission events in a FMDV outbreak.
Outbreaker (A) and SCOTTI (B) provide different interpretations of the 2007 South of England FMDV outbreak. A) “Beanbag” tree (see Fig A in S1 Text) of Transmission events inferred with Outbreaker. The two numbers on each transmission arrow represent respectively the number of nucleotide substitutions separating two hosts, and the inferred posterior support of the event (in this case always 1, meaning 100% support). All transmissions are inferred to be direct with more than 95% posterior probability. B) “Beanbag” tree of transmission events inferred with SCOTTI. Numbers within host circles represent the posterior probabilities of the corresponding host being the index host (the root) of the considered outbreak. Numbers on arrows represent the inferred posterior probabilities of the corresponding direct transmission events. Colour intensity is proportional to posterior probability.
