| a new species of dipetalonema (filarioidea: onchocercidae) from ateles chamek from the beni of bolivia. | we describe a new species of dipetalonema occurring in the body cavity of ateles chamek (humboldt, 1812) from north-central bolivia. morphologic characters serving to separate dipetalonema yatesi n. sp. from known forms include a vagina vera with a simple tube and thin walls and a left spicule, which possesses a handle shorter than the lamina (ratio 2.7); the latter displays an anterior membranous alae similar in length to the terminal flagellum, a distal extremity of the left spicule within a s ... | 2007 | 17626361 |
| prevalence and molecular phylogenetic characterization of trypanosoma (megatrypanum) minasense in the peripheral blood of small neotropical primates after a quarantine period. | neotropical primates of the cebidae and callitrichidae, in their natural habitats, are frequently infected with a variety of trypanosomes including trypanosoma cruzi, which causes a serious zoonosis, chagas' disease. the state of trypanosome infection after a 30-day quarantine period was assessed in 85 squirrel monkeys (saimiri sciureus) and 15 red-handed tamarins (saguinus midas), that were wild-caught and exported to japan as companion animals or laboratory animals, for biomedical research, re ... | 2008 | 18576832 |
| trypanosomes and microfilariae in feral owl and squirrel monkeys maintained in research colonies. | a group of 358 owl and squirrel monkeys imported from colombia, peru, and bolivia for the u.s. agency for international development malaria vaccine development program was examined for trypanosomes and microfilariae. trypanosoma rangeli, isolated by hemoculture from aotus nancymai, saimiri b. boliviensis, and s. b. peruviensis, accounted for 76.6% of all trypanosome infections. trypanosoma cruzi was isolated from 25 of 194 s. b. boliviensis, including two mixed infections with t. rangeli. identi ... | 1993 | 8357088 |
| chemotherapy of filariasis in squirrel monkeys (saimiri sciureus). | the effect of some known antifilarial drugs on naturally-occurring filariae in squirrel monkeys, saimiri sciureus, was evaluated. four drugs, dithiazanine iodide, naphuride sodium, thiacetarsamide sodium, and diethylcarbamazine were tested against dipetalonema gracile and tetrapetalonema marmosetae. dipetalonema caudispina was included in some of the studies using diethylcarbamazine. these are the three most commonly encountered filarial species in squirrel monkeys. dithiazanine iodide proved to ... | 1982 | 6890602 |
