Fig. 2From: The seal louse (Echinophthirius horridus) in the Dutch Wadden Sea: investigation of vector-borne pathogensPhylogenetic analysis of A. spirocauda. The phylogeny is based on the MAFFT alignments for a partial cox1 sequence and complete ITS2 rDNA region of A. spirocauda and other Acanthocheilonema species using Bayesian inference (Dirofilaria immitis sequence as outgroup). The A. dracunculoides ITS2 sequence is shorter and does not cover the whole sequence of A. spirocauda. Branch lengths are drawn proportionally to evolutionary distance (scale bar is shown). Numbers adjacent to nodes indicate posterior probabilities in per cent. Branch labels provide species names/host/two-letter country code/GenBank accession numberBack to article page
