The antioxidant defence mechanisms of parasite and host after chronic Hymenolepis diminuta infestation of the rat.
نویسندگان
چکیده
The aim of the present study was to determine antioxidant defence mechanisms in the rat and Hymenolepis diminuta after long-term infestation. We determined levels of oxidative stress markers, and activity of antioxidant enzymes in the rat small intestine and in particular parts of H. diminuta. Observed changes in antioxidant enzymes activity in H. diminuta and the rat intestine indicate the defence against parasitic infestation and probably allowed parasite to adapt and live in oxidative stress.

Establishment of Hymenolepis diminuta Life Cycle to Provide Parasite Mass Production
BACKGROUND The main object of this experimental work was to practise laboratory production both adult and the larval stage of Hymenolepis diminuta with conventional modification to make further studies easier.

متن کاملEstablishment 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...
متن کاملNew Data on Human Macrophages Polarization by Hymenolepis diminuta Tapeworm—An In Vitro Study
Helminths and their products can suppress the host immune response to escape host defense mechanisms and establish chronic infections. Current studies indicate that macrophages play a key role in the immune response to pathogen invasion. They can be polarized into two distinct phenotypes: M1 and M2. The present paper examines the impact of the adult Hymenolepis diminuta (HD) tapeworm and its ex...
متن کاملMonospecific helminth and arthropod infections in an urban population of brown rats from Doha, Qatar.
Parasitic infections were studied for the first time in an urban population of brown rats (Rattus norvegicus) from Doha. Only one species of helminth was found, the cestode Hymenolepis diminuta, and one ectoparasite, the flea Xenopsylla astia, from a sample size of 136 rats (52 males and 84 females). The prevalence of H. diminuta was 17.6%, increasing with host age but not in relation to host s...
