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...

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.

Cestodiases are common parasitic diseases of animals and humans. As cestodes have complex lifecycles, hexacanth larvae, metacestodes (including cysticercoids), and adults produce proteins allowing them to establish invasion and to survive in the hostile environment of the host. Hymenolepis diminuta is the most commonly used model cestode in experimental parasitology. The aims of the present stu...

Bertiella studeri is a rare parasite of humans and inhabits the small intestine. Monkeys are its natural hosts. Certain species of oribatid mites serve as intermediate hosts. Accidental ingestion of the mite containing the cysticercoid stage gives rise to human infection. The first case of human infection in Sri Lanka was reported in 1976 [1] and three more cases have been reported since [2,3]....

Two cysticercoids, belonging to ascocercus type, namely euascocercus and multicercus, were found in haemocoele of dragonfly larvae of the genus Aeshna from the lakes of the Magadan Province. The cysticercoid of Schistotaenia srivastavai Raush, 1970 (euascocercus) is formed of the outer (exocyst) and inner (endocyst) envelopes, containing the scolex and larval strobila. The outer and inner surfa...

background: hymenolepis diminuta is a cestod of rodents and rarely infects humans. infection in humans is via ingestion of infected insects. this study was aimed to detect h. diminuta cysticercoids in red flour beetles, tribolium castaneum, and cockroaches originated from different regions of iran. methods: the red flour beetles and cockroaches were collected from local bakeries in five cities ...

A study on the parasitofauna of 7 species of Iraqi reptiles revealed the presence of at least 8 adult helminth species and some tentatively identified larvae. The reptiles were Hemidactylus flaviviridis, H. persicus, Asaccus elisae, Spalerosophis d. cliffordi, Testudo g. terrestris, Mauremys c. caspica and Trionyx euphraticus. The helminths found comprised 1 species of digenetic trematodes (Tel...
