“…Published data show that different vertebrate hosts have variable levels of susceptibility to R. nana and other Hymenolepididae species (Woodland, 1924;Larsh, 1944;Schiller, 1959a, b;Litchford, 1963;De Rycke, 1966;Turton, 1971;Hopkins et al, 1972;Isaak et al, 1977;Murray et al, 1984;van Haeren & de Rycke, 1984;Ishih et al, 1992;Stradowski, 2004). It has been found that non-immunosuppressed M. unguiculatus have low susceptibility to the mouse isolates of R. nana used herein, even when different infection methods are employed.…”

A mouse-derived strain of Rodentolepis ( = Hymenolepis) nana was transferred to the Mongolian jird Meriones unguiculatus. It was found that M. unguiculatus has low susceptibility to R. nana mouse isolates. Likewise, adaptation of the parasite to jird hosts, in the absence of dexamethasone treatment, was not demonstrable, at least during ten-passage trials. Nevertheless, the parasite was able to establish, grow and develop to gravid adults in M. unguiculatus treated daily with dexamethasone. Prepatent periods in dexamethasone-treated jirds in ten-passage series ranged from 10 to 17 days post-infection (DPI), the average being 12 days, and the patent periods lasted from 18 to 30 DPI, with an average of 25 days. The population pattern of faecal egg output in immunosuppressed jirds suggests that under a daily dexamethasone treatment protocol, the parasite is able to maintain egg production as long as treatment is sustained.

“…This, it was felt, would minimize the effect of the actual contents of the lumenal environment on the lipid deposition in the worm, since all animals receive the same commercial rat food. This type of host comparison study is not without precedent as Ackert (1935), Larsh (1944Larsh ( , 1946, Voge (1952), Read and Voge (1954), and Read (1956) have used different strains and species of host in studying various responses by single parasitic types.…”
