Research on this parasite has mainly focused on epidemiological surveys and life cycle studies. So far, limited laboratory studies have been reported. Here, experimental infection of <jats:italic>E. shiquicus<\/jats:italic> metacestode in BALB\/c mice and Mongolian jirds (<jats:italic>Meriones unguiculatus<\/jats:italic>) was carried out to establish alternative laboratory animal models. Intraperitoneal inoculation of metacestode material containing protoscoleces (PSCs) obtained from infected plateau pikas were conducted on BALB\/c mice. Furthermore, metacestode material without PSCs deriving from infected BALB\/c mice was intraperitoneally inoculated to Mongolian jirds. Experimental animals were dissected for macroscopic and histopathological examination. The growth of cysts in BALB\/c mice was infiltrative, and they invaded the murine entire body. Most of the metacestode cysts were multicystic, but a few were unilocular. The cysts contained sterile vesicles, which had no PSCs. The metacestode materials were able to successfully infect new mice. In the jirds model, <jats:italic>E. shiquicus<\/jats:italic> cysts were typically formed freely in the peritoneal cavity; the majority of these cysts were free while a small portion adhered loosely to nearby organs. The proportion of fertile cysts was high, and contained many PSCs. The PSCs produced in Mongolian jirds also successfully infected new ones, which confirms that jirds can serve as an alternative experimental intermediate host. In conclusion, a laboratory animal infection was successfully established for <jats:italic>E. shiquicus<\/jats:italic> using BALB\/c mice and Mongolian jirds. These results provide new models for the in-depth study of <jats:italic>Echinococcus<\/jats:italic> metacestode survival strategy, host interactions and immune escape mechanism.<\/jats:p>","DOI":"10.1017\/s0031182023000604","type":"journal-article","created":{"date-parts":[[2023,7,3]],"date-time":"2023-07-03T01:29:26Z","timestamp":1688347766000},"page":"813-820","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Establishment
