The complete mitochondrial genome of Eimeria anseris from the wintering greater white-fronted goose in Shengjin Lake, China, and phylogenetic relationships among Eimeria species

Phylogenetic relationships of 52 Eimeria species based on COI sequences

“…The nucleotide compositions of the 52 COI sequences for Eimeria are biased toward A and T, with T being the most common nucleotide and G the least common. The mean total nucleotide composition was: A, 26.1%; C, 18.5%; G, 16.9%; and T, 38.5%; the average AT content (55.6%) being slightly higher than the CG content (44.4%), which is similar to the most Eimeria, in which the rarest nucleotide is G (Lin et al 2011;Ogedengbe et al 2014;Hafeez et al 2015;Liu et al 2019).…”

“…Eimeria can cause serious damage to the digestive tract of the host, resulting in malabsorption of nutrients and diarrhea, which causes decreased body weight gain, and possibly lead to death, and has been one of the biggest challenges faced by the global poultry industry (Lin et al 2011;Chengat Prakashbabu et al 2017;Song et al 2017). However, the relationships of Eimeria species are not clear at present (Ogedengbe et al 2013;Liu et al 2019).…”

“…COI gene provide useful markers for investigating population genetic structures, systematics and phylogenetics of organisms, it has been extensively used as genetic markers for phylogenetic analyses at different levels (Lin et al 2011;Liu et al 2019). Here, we sequenced the COI of three Eimeria species (E. tenella, E. mitis, E. anseri) isolated from wintering Anser albifrons feces which collected in Shenjin lake (E117 0 0 42.55 00 , N30 20 0 30.73 00 ), Anhui province of China in January, 2019.…”
