Evolutionary relationships of ompB gene Rickettsia sp. The evolutionary history was inferred using the Neighbor-Joining method. The analysis involved 704-bp (nucleotide 3556–4259 of R typhi ompB gene) of 46 nucleotide sequences. Sequences from subjects of AFIRE study are denoted with black triangle (▲). All positions containing gaps and missing data were eliminated. Evolutionary analyses were conducted in MEGA7
