Human intestinal parasites in Mahajanga, Madagascar: The kingdom of the protozoa
Fig 5
Molecular phylogenetic analysis of the four S. similis strains isolated in our study based on 18S rRNA sequences.
The evolutionary history was inferred by using the Maximum Likelihood method based on the Tamura 3-parameter model (1000 replicates) using MEGA6. Only bootstrap values higher than 70% are shown. The strains found in human stool (MAJ 224, MAJ171, MAJ 213, MAJ 237) are similar to each other and very similar to the CH394 strain found in Melampheus faber.
