Phylogenetic analyses of hairworms (class Gordiacea) from humans based on 18S rRNA (1,414 bp). The evolutionary history was inferred using the Neighbor-Joining (NJ) method. The evolutionary distances were computed using the Kimura-2 parameter method and are in the units of the number of base substitutions per site. Bootstrap values are shown next to the branches. A high bootstrap value 0.988 (number of 1,000 replicates) was obtained at a junction of Paragordionus spp. and the present 2 worms.
