A validated method to identify Echinococcus granulosus sensu lato at species level.

A validated method to identify Echinococcus granulosus sensu lato at species level. Infect Genet Evol. 2020 Sep 29;:104575 Authors: Santolamazza F, Santoro A, Possenti A, Cacciò SM, Casulli A Abstract The zoonotic tapeworm Echinococcus granulosus sensu lato (s.l.) represents a species complex encompassing multiple causative agents of cystic echinococcosis, a neglected tropical disease affecting more than one million people in the world. At least eight genotypes, grouped in five species, are currently recognized within this species complex, and they differ in terms of relative public health impact. Here we present a molecular method that first identifies the common E. granulosus sensu stricto (s.s.) (genotypes G1 and G3) based on a PCR-RFLP assay, and can further identify the remaining species based on a multiplex PCR assay. We demonstrate the applicability of the method to DNA extracted from parasitic cyst material of human and animal origin, preserved in ethanol or frozen. The method has been developed and validated at the European Union Reference Laboratory for Parasites (EURLP), according to the ISO/IE 17025. PMID: 33007497 [PubMed - as supplied by publisher]
