Fig. 1From: First molecular detection and genetic characterization of Coxiella burnetii in Zambian dogs and rodentsEvolutionary relationships of Coxiella strains based on isocitrate dehydrogenase (icd) gene sequences. The neighbor-joining tree was constructed using Kimura 2-parameter model in MEGA software. The GenBank accession numbers are in parentheses while the host and country of origin are in square brackets. The Coxiella strains characterized in this study are in bold and red text, with the district of origin indicated after the colon. Bootstrap values ≥ 50% are shown at branch nodes. The scale-bar indicates the number of substitutions per siteBack to article page
