Phylogenetic tree of the 17-kDa - gltA - ompA - rrs - sca4 - ompB concatenated sequence of Rickettsia slovaca (â–²) and R. raoultii (â—†) from Melophagus ovinus obtained in this study and sequences from Rickettsia species retrieved from the GenBank database. The tree was constructed on the basis of neighbor-joining (NJ; 500 bootstrap replicates) and maximum-likelihood (ML, 1,000 bootstrap replicates) analyses using MEGA6. The scale bar represents the inferred substitutions per nucleotide site. The relative support for clades in the tree was produced from the NJ and ML analyses
