Though recent advancements in scientific knowledge have been gained, gaps still remain about the biology of this filarioid, as well as its genetic structure. Based on mitochondrial genes, two highly divergent genotypes were identified, in the Iberian Peninsula (genotype 2) and Europe, Asia, and the United States (genotype 1), meanwhile only a draft nuclear genome of\n                      <jats:italic toggle=\"yes\">O. lupi<\/jats:italic>\n                      from the United States is available.

Despite recent scientific advances, gaps remain in both the biology and genetic structure of this parasite. To date, two genotypes have been described (genotype 1 distributed in Europe, Asia, and the United States, and genotype 2 circulating in the Iberian Peninsula) based on mitochondrial gene analysis. This study provided three distinct genomes (nuclear, mitochondrial, and\n                        <jats:italic toggle=\"yes\">Wolbachia<\/jats:italic>\n                        endosymbiont) of\n                        <jats:italic toggle=\"yes\">O. lupi<\/jats:italic>\n                        isolated from a dog living in Portugal.
