Phylogenetic tree (left) and aligned sequences (right) of Orientia spp. and locally endemic Rickettsia spp. in a study of Orientia genus endemicity among severe infectious disease cohorts, Uganda. We compared the 16S rRNA gene with an Orientia infection (case D) in Uganda. We aligned the 96-bp amplicon region and created the tree by using the neighbor-joining algorithm in R (The R Foundation for Statistical Computing, https://www.r-project.org). GenBank accession numbers of reference sequences are in parentheses. A single polymorphism aligned with Candidatus O. chuto, possibly differentiating case D from other Orientia spp. Scale bar indicates nucleotide substitutions per site.
