Novel chlamydiae in whiteflies and scale insects: endosymbionts 'Candidatus Fritschea bemisiae' strain Falk and 'Candidatus Fritschea eriococci' strain Elm, by K. D. E. Everett, M. Thao, M. Horn, G. E. Dyszynski and P. Baumann
International Journal of Systematic and Evolutionary Microbiology vol. 55, part 4, pp. 1581 - 1587

Supplementary Fig. S1. Clustering of 331 chlamydial 16S rRNA gene signature sequences. An uncorrected neighbour-joining tree is shown. The nine species from the Chlamydiaceae represent the 177 available sequences. This tree reflects the diversity of chlamydiae. Source/host is indicated by colour: red, humans (red CRGs are from human blood or aortic aneurysms); blue, animals/insects; green, fertilizer; black, water or other micro-organisms (Meijer et al., 2000). Strains obtained from two or more hosts/environments are indicated with asterisks in the other colour(s). Validly published names and Candidatus species are in boldface/italic type. Bar, 5 substitutions per 100 nucleotides.
