Horse-Specific Cryptosporidium Genotype in Human with Crohn's Disease and Arthritis
Figure

Figure. Maximum-likelihood tree based on partial sequences of 60-kD glycoprotein of Cryptosporidium spp. from a 13-year-old immunocompromised girl and a horse she rode in Poland (and reference sequences. Bold and asterisks indicate isolates reported from humans; gray shading indicates isolates reported from animals. The general time reversible model was applied using a discrete gamma distribution. Robustness of the phylogeny was tested with 1,000 bootstraps. Values along the branches indicate bootstrap values with >50% support. GenBank accession number are indicated in brackets. Country of origin of Cryptosporidium sp. horse genotype isolates is indicated by 3-letter International Organization for Standardization country abbreviation. Scale bar indicates nucleotide substitutions per site.
