Table 1.
Posterior state transition rate estimates from the Bayesian analysis of bartonella gltA sequences, with data partitions for bat host family, superfamily, suborder, and geographic region. Only transition rates with a median rate greater than one are shown. Probability estimates indicate the likelihood of the median number of transition occurring since the time of the common ancestor of the 173 genotypes, as tested against a null gamma distribution (shape = 1, scale = 1). Bolded probability values are marginally significant (0.05 < P ≤ 0.1), underlined values are statistically significant (P < 0.05). Clock rates reflect the mean number of state transitions occurring across all nodes of the tree.
