Molecular characterization of Ascaris suum nematode infection in the lung of a dog in China, 2019. Phylogenetic trees inferred by using Tamura-Nei model-based maximum likelihood (ML) and GTR+I+G model-based Bayesian inference (BI) analyses based on the partial sequences of the nuclear 18S rDNA gene (a) and the mitochondrial 12S rDNA gene (b) of the isolate from the dog (bold and marked with a solid black circle) and other related species. Loa loa (a) and species of Anisakis and Ortleppascaris (b) were used as outgroups. The numbers along the branches indicate bootstrap values resulting from different analyses in the order ML/BI; values > 70% (ML) and 0.95 (BI) are shown
