development of dipetalonema gracile and d. caudispina to the infective stage in culicoides hollensis.	the microfilariae of 2 species of dipetalonema (i.e., d. gracile and d. caudispina), common parasites of south american monkeys, develop to the third (infective) stage in the biting midge, culicoides hollensis. development of both species occurs in the abdominal fat body; d. gracile requires 13 days and d. caudispina 9 days. despite similarities in the patterns of development of both species, the third-stage larvae of each is morphologically distinct.	1979	571910
exfoliative colpocytology: a method for the diagnosis of capuchin monkey filariasis?	during vaginal fluid examinations (papanicolaou) to study the physiological sexual cycle of cebus sp., abundant dipetalonema gracile microfilariae (110-160 microns x 4-5 microns, without a sheath) were encountered in the genital fluid, but not in peripheral blood. considering the great difficulty in diagnosing this obscure parasitosis, exfoliative colpocytology was found to be an efficient diagnostic.	1992	1413462
[microfilariae in vaginal exudates from argentinian apes].	the finding of dipetalonema gracile larves in vaginal content of capuchin monkeys (cebus apella) was reported. the sizes of microfilarias, which did not present capsule, were 110-160 microns long and 4-5 microns wide. microfilarias did not find in peripheral blood. assuming that the cycle of this worm is not yet elucidated, the authors postulate that the presence of larves in the female genital tract could relate with venereal transmission.	1991	1670474
longevity of microfilariae following removal of the adult worms.	the present study was undertaken to determine the longevity of a population of microfilariae in a natural host following the removal of the adult worms without drug intervention. four squirrel monkeys previously infected with dipetalonema gracile were allowed to develop stable microfilaremias. all adult worms were then removed surgically from the peritoneal cavity. weekly microfilaria counts were made on each animal and the decline in microfilariae recorded. at the time of adult worm removal, mi ...	1986	3563316
development of dipetalonema gracile in the squirrel monkey (saimiri sciureus), with notes on its biology.	infective larvae of dipetalonema gracile, which had developed in culicoides hollensis, were inoculated into 4 laboratory-born squirrel monkeys, saimiri sciureus. weekly blood sampling revealed the mean prepatent period to be 297 days. all 4 monkeys developed patent infections in which peak microfilaremias were reached 13 to 18 wk after patency. two laparotomies, performed at 27 and 64 wk, were conducted to evaluate pathological involvement and, at that later time, to recover adult parasites. sli ...	1985	3981344
the prevalence of trypanosomes and microfilariae in panamanian monkeys.	a total of 3,523 wild caught monkeys from panama was examined for blood parasites from august 1968 through june 1972. trypanosomes or microfilariae were observed in the blood of 31.1% of the monkeys. mixed infections, with microfilariae and trypanosomes, were detected in 6.6% of the animals. trypanosoma cruzi was found in marmosets. saguinus geoffroyi (12.2%), in white-faced capuchins, cebus capucinus (5.0%), in squirrel monkeys, saimiri sciureus (1.7%) and in black spider monkeys, ateles fuscic ...	1974	4217567
dipetalonema gracile in a capuchin monkey (cebus capucinus).		1970	4992912
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
[new data on the dipetalonema lineage (filarioidea, nematoda)].	the evolutionary line of dipetalonema can apparently be divided into four groups: i: australian species; ii: paleoendemic south american species; iii: the tetrapetalonema group; iv: the acanthocheilonema group. loxodontofilaria at present insufficiently known to be classified and several species belonging to the acanthocheilonema group are the object of the present study. descriptions are given of loxodontofilaria asiatica n. sp., parasite of elephas indicus in burma, cercopithifilaria degraaffi ...	1982	6891995
courses of infections with plasmodium falciparum in own monkeys displaying a microfilaremia.	infections with the uganda palo alto, malayan camp-ch/q, vietnam oak knoll, and vietnam smith strains of plasmodium falciparum in owl monkeys (aotus trivirgatus griseimembra) with concomitant microfilaremias usually, but not always, followed a more benign course than infections with the same strains in monkeys free of filarial infections. four distinct microfilariae were identified in systematic examinations of 26 monkeys, 5 with self-limited infections with p. falciparum, 9 with normally benign ...	1981	7011072
phylogeny of wolbachia pipientis based on glta, groel and ftsz gene sequences: clustering of arthropod and nematode symbionts in the f supergroup, and evidence for further diversity in the wolbachia tree.	current phylogenies of the intracellular bacteria belonging to the genus wolbachia identify six major clades (a-f), termed 'supergroups', but the branching order of these supergroups remains unresolved. supergroups a, b and e include most of the wolbachiae found thus far in arthropods, while supergroups c and d include most of those found in filarial nematodes. members of supergroup f have been found in arthropods (i.e. termites), and have previously been detected in the nematode mansonella ozza ...	2005	16339946
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
