Comparison of the compositions of antioxidant enzymes in 59 nematodes. The sizes of the circles represent the number of antioxidant enzymes in a category. The biology of lifestyle, human infection, definitive host range, and intermediate host range of the nematode are shown. Taxonomic classification is retrieved from the Taxonomy database. The topology of nematode phylogeny is inferred by combining previous studies [10, 24, 36]. The designated shapes for clades and colors for subclades are used consistently throughout the study
