Larval occurrence of hydatigera taeniaeformis Batsh [1786] [cestoda: taeniidae] in the liver of wild rodents in Egypt

Hydatigera taeniaeformis Batsch [1786] was found in the liver of six species of Egyptian wild rodents. The total incidence of this larval stage was found to be 20.0% among cestode infection. It was found in 40.9% Rattus norvegicus, 33.3% Gerbillus gerbillus, 26.8% Rattus rattus, 25.0% Mus musculus, 16.6% Acomys cahirinus and 7.2% Arvicanthis niloticus. The cysts of Hydatigera taeniaeformis was always occupying the marginal surfaces of both right and left lobes and sometimes there was a double cyst contained two strobilae. The rostellar hooks used for identification. The strobilae obtained were in different stages of development. The rostellar hook system was complete and so the suckers, but the segment showed no maturation. Morphological characters and role of rodents as intermediate host for such cestode are discussed

Capillaria hepatica infection of wild rodents in Peninsular Malaysia.

Capillaria hepatica infection in wild rodents collected from the States of Kelantan, Selangor and Johore in Peninsular Malaysia since 1973 is reported. A total of 1,258 rodents consisting of 20 species of house, field and forest rats, and 7 species of squirrels were examined for the parasite and 17 species consisting of 111 murids and 1 flying squirrel were found infected. The house rat, Rattus norvegicus had the highest prevalence rate, followed by 3 species of field rats, R. tiomanicus, R. argentiventer and Bandicota indica. The prevalence of infection was low among forest rats with the exception of Lenothrix canus. Only 1 flying squirrel, Hylopetes spadiceus was found with the parasite. The prevalence of infection in relation to the host behaviour and habitats was discussed. C. hepatica appears to be widespread throughout Malaysia with a wide range of hosts among rodent species. Some new host records are presented herein.
