Structure views of mitogenomes of 33 chicken Eimeria isolates identified in this study. a–g Mitochondrial genome organizations of the Eimeria isolates 1–33 corresponding to seven chicken-infecting Eimeria species. Isolates in the same species are arranged together and contrast with the reported mitogenome organization. Red color indicates protein-coding genes, blue color indicates fragments of rRNA genes, green and purple colors indicate positive and negative GC-skew, respectively, and black color indicates the GC content of every position in the genome. h The average AT-skew and GC-skew values of the complete mitogenomes (Entire), concatenated PCG datasets (PCGs), LSU and SSU rRNAs of each species
