Fig. 2From: Molecular detection of Rickettsia in fleas from micromammals in ChilePhylogenetic tree of gltA 830-bp gene of Rickettsia. The values on each node show the Bayesian probability of each clade. The accession number for each sequence is indicated. Flea species and locality are indicated for the sequences generated in this study. The principal clades are labelled R1, R2a and R2bBack to article page
