Efficacy of condensed tannins against larval Hymenolepis diminuta (Cestoda) in vitro and in the intermediate host Tenebrio molitor (Coleoptera) in vivo

Efficacy of condensed tannins against larval Hymenolepis diminuta (Cestoda) in vitro and in the intermediate host Tenebrio molitor (Coleoptera) in vivo.

Natural anti-parasitic compounds in plants such as condensed tannins (CT) have anthelmintic properties against a range of gastrointestinal nematodes, but for other helminths such effects are unexplored. The aim of this study was to assess the effects of CT from three different plant extracts in a model system employing the rat tapeworm, Hymenolepis diminuta, in its intermediate host, Tenebrio m...

Efficacy of condensed tannins against larval Hymenolepis diminuta ( Cestoda ) in 1 vitro and in the intermediate host Tenebrio molitor ( Coleoptera ) in vivo

Effect of age of the intermediate host Tribolium confusum (Coleoptera) on infection by Hymenolepis diminuta (Cestoda).

A cross-sectional study of 27 cohorts of Tribolium confusum aged 2-78 wk was done to examine effects of host age on exposure to eggs of Hymenolepis diminuta under standardized conditions. Pre-exposure, fasting, and postexposure mortality were low, sex ratio was equal, and fecundity of hosts was high during the first 30 wk, followed by increasing mortality and male bias of the sex ratio, and dec...

Sex differences in frass production and weight change in Tenebrio molitor (Coleoptera) infected with cysticercoids of the tapeworm Hymenolepis diminuta (Cestoda)

In their intermediate host, parasites alter aspects of host physiology including waste production and body weight. Further, this alteration may differ between female and male hosts. To study this, a beetle (Tenebrio molitor)-tapeworm (Hymenolepis diminuta) system was used. Infected and uninfected male and female beetles were individually housed in vials without food. Each beetle's weight change...

Therapeutic efficacy of Zanthoxylum rhetsa DC extract against experimental Hymenolepis diminuta (Cestoda) infections in rats.

Zanthoxylum rhetsa DC (Rutaceae), commonly called prickly ash, is used in the folk medicine of Naga tribes in India as a deworming remedy. In the present study, the therapeutic efficacy of Z. rhetsa leaf extract was investigated against experimental Hymenolepis diminuta (Cestoda) infections in albino rats. The efficacy of extract was determined on the basis of reduction in the eggs per gram of ...
