A162 EXPULSION OF THE TAPEWORM HYMENOLEPIS DIMINUTA FROM MICE OCCURS INDEPENDENT OF SEROTONERIC SIGNALLING

Thymus dependence of tapeworm (Hymenolepis diminuta) elimination from mice.

Although normal mice eliminated the lumen-dwelling intestinal cestode Hymenolepis diminuta by day 21 post-cysticercoid inoculation, congenitally thymus-deficient (nude) mice maintained their work burdens. Nude mice grafted with thymus glands or injected with thymus cells eliminated their worms.

Effect of the expulsion phase of Trichinella spiralis on Hymenolepis diminuta infection in mice.

The rapid elimination of the intestinal phase of Trichinella spiralis in NIH mice is associated with progressive inflammation of the intestinal tract. The non-specific effects of this inflammation were studied in mice concurrently infected with an unrelated parasite, Hymenolepis diminuta, which does not stimulate a visible inflammatory response but is also immunologically rejected by this strai...

Identification of an NAD-dependent 3-acetamidobenzamide-sensitive system in oncospheres from the tapeworm Hymenolepis diminuta.

( a ) Autoradiograph of RNA species which arise in a transcription reaction. Nomenclature, fragment sizes and experimental conditions are as in 141. RNA circles are arrowed wth their tentative sizes in nucleotides. Precursor (p), ribozyme (IVS), ligated exons (SE3E) and precursor in which the downstream exon has been hydrolysed (5EI) are depicted. ( b ) Autoradiograph of radiolabelled amplified...

Establishment Success of the Beetle Tapeworm Hymenolepis diminuta Depends on Dose and Host Body Condition

Parasite effects on host fitness and immunology are often intensity-dependent. Unfortunately, only few experimental studies on insect-parasite interactions attempt to control the level of infection, which may contribute substantial variation to the fitness or immunological parameters of interest. The tapeworm Hymenolepis diminuta-flour beetle Tenebrio molitor model-has been used extensively for...
