Phylogenetic tree of Rickettsia species inferred with partial sequences (490 bp) of the ompA gene using the neighbor-joining method showing the novel obtained sequences (n = 11) from Tunisian small ruminant ticks. Bootstrap values (1,000 replicates) are indicated in each node (only percentages >50% are shown). The 11 genotypes of Rickettsia spp. obtained in the present study are indicated in bold. The host or vector, the genotype, strain or isolate name, the country of origin, and the GenBank accession number are represented. One R. felis ompA partial sequence was added as an outgroup.
