Dirofilaria repens phylogenetic trees from study of ocular dirofilariasis in California, USA. A) ITS gene sequences; B) 28S gene sequences C) COX1 gene sequences. All 3 marker gene comparisons confirmed the study sample belonged to D. repens. Genbank accession numbers are indicated. Branch numbers indicate nucleotide substitutions per site. ITS, internal transcribed spacer.
