| falcaustra lowei n. sp. and other helminths from the tarahumara frog, rana tarahumarae (anura: ranidae), from sonora, mexico. | seventy-four specimens of falcaustra lowei n. sp. were recovered from the intestines of 9 of 42 (21%) tarahumara frogs. rana tarahumarae, from sonora, mexico. f. lowei is the 14th nearctic species to be described and belongs to that group of species possessing a pseudosucker, namely f. catesbeianae, f. chabaudi, f. chelydrae, f. mexicana, and f. wardi. the new species can be readily differentiated from these by the arrangement of caudal papillae and length of spicules. priority description of f. ... | 2001 | 11318564 |
| helminth infracommunities of rana vaillanti brocchi (anura: ranidae) in los tuxtlas, veracruz, mexico. | a total of 76 adult individuals of rana vaillanti were collected in laguna escondida, los tuxtlas, veracruz, mexico, and their helminth infracommunity structure was determined. among the 21 helminth taxa collected (10 digeneans, 8 nematodes, and 3 acanthocephalans), the digenean langeronia macrocirra reached the highest prevalence (64.4%), mean abundance (6.6), and mean intensity (10.4), as well as the highest total number of individuals (499). only 2 frogs were uninfected, the remainder harbore ... | 2004 | 15357055 |
| helminth parasites in chaunus marinus and cranopis valliceps (anura: bufonidae) from lagunas yalahau, yucatan, mexico. | eight helminth taxa were found parasitizing chaunus marinus (n = 40) and cranopsis valliceps (n = 40) from the parque estatal lagunas yalahau, yucatan, mexico. seven taxa (2 digeneans: langeronia macrocirra, mesocoelium monas; 1 acanthocephalan: oncicola sp.; 3 nematodes: rhabdias füleborni, aplectana itzocanensis, cruzia morleyi; and a nematode larva) were found in c. marinus, while 4 taxa (all nematodes: rhabdias fuelleborni, aplectana itzocanensis, ozwaldocruzia sp., and a nematode larva) wer ... | 2008 | 18605789 |
| helminth parasites of the leopard frog lithobates sp. colima (amphibia: ranidae) from colima, mexico. | the helminth fauna inhabiting lithobates sp. colima from ticuizitán, colima, mexico, comprises 10 species: 4 digeneans ( clinostomum sp., glypthelmins quieta , haematoloechus sp., and langeronia macrocirra ), 5 nematodes ( aplectana itzocanensis , cosmocerca podicipinus , foleyellides striatus , oswaldocruzia subauricularis , and rhabdias sp.), and 1 cestode (cyclophyllidea). glypthelmins quieta , l. macrocirra , and a. itzocanensis represent new host records. these observations, added to previo ... | 2010 | 20496957 |
| molecular evidence that langeronia macrocirra and langeronia cf. parva (trematoda: pleurogenidae) parasites of anurans from mexico are conspecific. | the genus langeronia parasitizing the intestine of several species of anurans is distributed from north to central america. we identified langeronia macrocirra and langeronia cf. parva from the same host and localities, and present here new data not applicable about their tegumental surface by scanning electron microscopy. we compared sequences of the rdna its2 region and mtdna cox1 gene for the two morphotypes. its2 exhibited a high degree of conservation. phylogenetic reconstruction using cox1 ... | 2010 | 21271852 |
