To investigate the prevalence and molecular characteristics of Cystoisospora sp. in blue fox (Alopex lagopus), Sheather’s sugar floatation method was conducted to detect coccidia in 423 fresh fecal samples randomly collected from blue fox farms from three cities in China. The overall prevalence of coccidia was 1.4% (6/423), and three Cystoisospora sp. (Cystoisospora fennechi, Cystoisospora sp. I and Cystoisospora vulpina) were identified by their morphological characteristics. The 18S ribosomal RNA (rRNA) and cytochrome c oxidase subunit I (COI) locus sequences were sequenced for molecular biological identification, homology comparison, and phylogenetic analysis of Cystoisospora sp. by single-oocyst selection technology and multi-locus-nested PCR amplification. At the 18S rRNA and COI loci, C. vulpina had 99.48% and 99.59% homology, respectively, with Cystoisospora canis and Cystoisospora ohioensis from canines. Phylogenetic analysis indicated that C. vulpina was clustered in a clade with Cystoisospora sp. from Canidae, which the relatives are consistent with the hosts. To our knowledge, this is the first report on molecular identification and evolutionary analysis of C. vulpina at two different loci. [ABSTRACT FROM AUTHOR] |
