| efficacy of ivermectin and oxfendazole against taenia solium cysticercosis and other parasitoses in naturally infected pigs. | smallholder semi-confined pig production is a fast growing practice in sub-saharan africa with an unfortunate outcome of high prevalence of taenia solium cysticercosis and other parasitoses. the widely used anthelmintic for control of endo and ecto-parasites in pigs in the area is ivermectin at a recommended dose of 0.3mg/kg. this study was conducted to evaluate the efficacy and safety in pigs after subcutaneous injection of ivermectin (ivm, 0.3mg/kg) and orally administration of oxfendazole (of ... | 2013 | 23806569 |
| new insights in cysticercosis transmission. | taenia solium infection causes severe neurological disease in humans. even though infection and exposure to swine cysticercosis is scattered throughout endemic villages, location of the tapeworm only explains some of the nearby infections and is not related to location of seropositive pigs. other players might be involved in cysticercosis transmission. in this study we hypothesize that pigs that carry nematodes specific to dung beetles are associated with cysticercosis infection and/or exposure. ... | 2014 | 25329903 |
| development of some larval nematodes in experimental and natural animal hosts: an insight into development of pathological lesions vis-a-vis host-parasite interactions. | infective third-stage larvae of three spiruroid nematodes, ascarops strongylina and physocephalus sexalatus of pigs and spirocerca lupi of dogs, were recovered from 14 species of coprophagous beetles belonging to 4 different genera. these larvae were fed to rabbits and/or guinea pigs to study their development in these experimental hosts. larvae of a. strongylina reached the adult stage in all rabbits and one guinea pig. the adult worms recovered in these hosts were 40% and 4%, respectively, and ... | 2013 | 24453801 |
| the effect of a nematode parasite on feeding and dung-burying behavior of an ecosystem engineer. | dung beetles (genus phanaeus) consume feces in both their larval and adults forms and because of their unique dietary niche, and behaviors associated with the burial of feces, are considered ecosystem engineers. in addition, because these insects subsist on a diet composed exclusively of feces, it is likely they encounter parasitic propagules more frequently than other animals do. parasites often alter their host's behavior, so we set out to test whether physocephalus sexalatus (a cosmopolitan n ... | 2014 | 24737785 |
