Evolutionary and phylogenetic relationships between E. zuernii and other congeneric species. a Patterns of K2P distance between Eimeria zuernii and other 30 Eimeria species determined on the basis of single and concatenated mt PCGs. Gray lines indicate the same K2P distance from the center. Black dots show the relative K2P distances between E. zuernii and other eimerian parasites. Dots closer to the edge of the patterns indicate a smaller K2P distance between E. zuernii and the corresponding species. Species abbreviations: E. anseris, Eans; E. chapmani, Echa; E. kofoidi, Ekof; E. legionensis, Eleg; Eimeria sp._JRBarta-2021b, Espj; E. acervuline, Eace; E. brunetti, Ebru; E. lata, Elat; E. maxima, Emax; E. mitis, Emit; E. nagambie, Enag; E. necatrix, Enec; E. praecox, Epra; E. tenella, Eten; E. zaria, Ezar; Eimeria cf._ictidea_JRB-2016, Ecfi; E. falciformis, Efal; E. furonis, Efur; E. leuckarti, Eleu; E. mephitidis, Emep; E. flavescens, Efla; E. intestinalis, Eint; E. irresidua, Eirr; E. kongi, Ekon; E. magna, Emag; E. media, Emed; E. vejdovskyi, Evej; E. adenoeides, Eade; E. gallopavonis, Egal; E. meleagridis, Emel. b Phylogenetic tree inferred by MP, ML, and BI algorithms using complete mitogenome datasets of E. zuernii and other congeneric species. Eimeria species, together with their branches, are marked with different colors according to host origins as follows: bird in light blue, chicken in dark blue, horse in light green, mephitis in dark red, mouse in yellow, mustela in purple, rabbit in green, turkey in blue, and yak/cattle in red. Eimeria zuernii sequenced in this study is indicated in bold font along with a star. The color boxes at each node showed bootstrap values for MP/ML/BI
