A survey was conducted on 30 Danish mink farms from April to October 2016 to determine the prevalence and species of Eimeria in Danish farmed mink. In total, 2.6% of mink faecal samples (108/4140) were positive for Eimeria vison-like oocysts by microscopy, with 24.8% (78/315) of mink being positive at least once during the study period. Morphological analysis of sporulated oocysts (n = 20) identified Eimeria vison-like oocysts measuring 21.0 × 13.8 μm with a length/width (L/W) ratio of 1.5. Phylogenetic analysis of 18S rRNA sequences (1221 bp) from three positive mink indicated that Eimeria vison-like shared the highest genetic similarity to Eimeria sp. ex Apodemus agrarius from a Striped field mouse (A. agrarius) from the Czech Republic (99.6%). Analysis of a shorter region of 18S (531 bp) revealed that the E. vison-like genotype sequences grouped in the same clade and shared 97.7% similarity with E. furonis. At the cytochrome c oxidase subunit I (COI) locus, mink-derived sequences were not available from GenBank and phylogenetic analysis placed the novel E. vison-like in a clade with E. cf. ictidea (99.4% similarity) from a black footed ferret (Mustela nigripes) from Canada.
