Abstract Ferretti G. , Gabriele F. and Palmas C. 1981. Development of human and mouse strain of Hymenolepis nana in mice. International Journal for Parasitology11: 425–430. An Hymenolepis nana strain isolated from human faeces was transferred in the mouse. At first, the q ratio (the number of parasites to the number of eggs used) was very low. After 10 passages adaptation was complete: when mice of different age and strain (CD1 and BDF1) were infected with eggs of the above strain and eggs of 2… Expand

In order to study the infectivity and development of the human strain of Hymenolepis nana in mice, ahuman strain of H. nana was inoculated into ICR mice and the infection rate and worm recovery rate were 69% and 17%, respectively. Expand
Experimental infection and adaptation of Rodentolepis nana to the Mongolian jird Meriones unguiculatus
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. Expand
It was clear that storage of eggs had a deteriorating effect and that the egg infectivity was dependent upon storage time, and the transmission potential capacity of the human strain of V. nana by mice can not be ignored. Expand
Resistance of mice to infection with the human strain of Hymenolepis nana.
Six attempts were made to infect mice by feeding them eggs of the human strain of Hymenolepis nana, but none was successful. No eggs were found in the mouse faeces 14 days after feeding, and no adultExpand
Gene-based molecular characterization of cox1 and pnad5 in Hymenolepis nana isolated from naturally infected mice and rats in Saudi Arabia
Results demonstrated that the present species are deeply embedded in the genus Hymenolepis with close relationship to other Hymenolespis species, including H. nana as a putative sister taxon, and that the isolates cannot be categorized as belonging to two different groups with origins in Makkah and Riyadh.

Characterisation of Community-Derived Hymenolepis Infections in Australia
A mitochondrial gene, the cytochrome c oxidase subunit 1 (C01) gene and a non-ribosomal nuclear gene, paramyosin, were characterised in a number of Hymenolepis isolates from different hosts, indicating that the 18S gene was too conserved for further genetic characterisation of isolates of H. nana from differenthosts.

Kinetics of mast cells, eosinophils and phospholipase B activity in the spontaneous-cure response of two strains of mice (rapid and slow responder) to the cestodeHymenolepis nana
Findings suggest that the prolongation of H. nana infection in C3H mice may be related to the delayed appearance of MMCs and eosinophils, which triggers a slower generation of the intestinal inflammation response. Expand
Host response of flour beetles, Tribolium confusum to reinfection with larval stage of Hymenolepis nana
The results revealed that the beetles can be infected more than once, and cysticercoids can live through the life of the beetles, there is no effective host resistance associated with a number of infections, nor is there effective interference with cysticERcoids development. Expand
A molecular phylogeny of nuclear and mitochondrial sequences in Hymenolepis nana (Cestoda) supports the existence of a cryptic species
The results obtained from faster evolving genes, and the epidemiological evidence, suggest that the life-cycle of H. nana is a species complex, or ‘cryptic’ species (=morphologically identical yet genetically distinct). Expand
Hydatidosis in Sardinia: review and recommendations.
The eradication campaign should result in a gradual reduction of infection rate from 80% to 10% in sheep, from 30% to 3-5% in dogs and in a reduction of human morbidity from 200 to 15 cases, equal to a prevalence rate of 1 per 100,000 inhabitants. Expand


A mechanism to account for mouse strain variation in resistance to the larval cestode, Taenia taeniaeformis.
It is suggested that, in relatively resistant mouse strains, host protective antibodies prejudice the establishment (or subsequent survival) of larvae prior to the full expression of protective mechanisms in the establishing larvae. Expand

Mice initially infected with Hymenolepis nana eggs became completely immune to challenge with mouse-derived cysticercoids (cysts) after more than 10 days, a strong indication that H. nana successively changes its immunogenicity during development, each stage stimulating immunity after a time lag.

Methodology in experimental infections of mice with Hymenolepis nana
A “natural” infection technique based on the uptake of eggs with feed that may be attained even in the case of large numbers, and in mice infected with many eggs, following treatment with ionizing radiations, q is greater than in the controls. Expand

A series of four experiments revealed that the sex of mice has little or no effect on susceptibility to infection and the importance of quantitative study of cyst size as well as cyst number is emphasized. Expand
The mode of passive protection against Hymenolepis nana induced by serum transfer.

A protective immunity against the cestode Hymenolepis nana was transferred with serum taken from actively immunized mice, and the major effect of immune serum was damaging hatched oncospheres in both the intestinal lumen and the villi within 1 day post infection. Expand
A probabilistic approach to the statistical analysis of experiments on helminth parasites.
A probabilistic method, based on a Bayesian approach, is proposed for the evaluation of results obtained in experimental infections induced by microscopic eggs (or larvae) whose exact number is not directly known; the results are represented by normalized likelihood functions (NLF) or, more generally, through final probability distributions.
