Abstract：This review focuses on biological characteristics of Echinococcus felidis including molecular genetic markers,species status,host coverage,geographical distribution,epidemiological implications,phylogeny,and evolution. The molecular genetic markers are involved in mitochondrial cox1 (cytochrome C oxidase subunit 1) and nad1 (nicotinamide adenine dinucleotide dehydrogenase subunit 1) genes,nuclear protein-coding gene sequences such as elp (ezrin-radixin-moesin-like protein),ef1a (elongation factor 1 alpha),pepck (phosphoenolpyruvate carboxykinase),pold (DNA polymerase delta),and ribosome RNA gene sequences such as ITS1 and 18S rRNA. The establishment of species status is based on distinctly discriminated morphological characteristics such as hooks on the rostrum with apparent rugae,the special definitive host (lions),and divergence of DNA sequences,etc. between E. felidis and other Echinococcus species. In brief,the review has provided researchers and experts in the field of echinococcosis with fundamental background knowledge and guidelines for future research directions,clinical and epidemiological investigations,and prevention and control of echinococcosis.
