Phylogenetic relationships of Toxocara/Toxascaris spp. from wild and domestic canine and feline carnivores and other related ascaridoid species. The phylogenetic topologies were inferred on the basis of nuclear ITS (a) and mitochondrial cox2 (b) and nad1 (c) as well as a combination of cox2 and nad1 (d) sequences using Bayesian inference (BI) and maximum likelihood (ML) methods. The reference sequences for species of Ascaris were used the outgroups. All species information about ascaridoid nematodes included in this study is summarized in Table 1. Species of Toxocara/Toxascaris recovered from wild and domestic canids and felids were genetically divided into three lineages, i.e. Toxocara canis, T. cati and Toxascaris leonina and indicated by three differently coloured sectors with T. canis in red, T. cati in pink and T. leonina in green. The numbers along the branches show bootstrap values resulting from different analyses in the order BI/ML; values < 50% are not shown
