Diversity and geographic distribution of haplotypes of Dirofilaria immitis across European endemic countries
Abstract Background Dirofilaria immitis, also known as heartworm, is one of the most important parasitic nematodes of domestic dogs, causing a potentially serious disease, cardiopulmonary dirofilariosis, which can be lethal. This species seems to be less 'expansive' than its sister species...
