Abstract Members of the genus Oncicola Travassos, 1916 are generalist parasites able to infect a broad spectrum carnivorous hosts, such as marsupials, procyonids, felids, and canids, distributed globally. Adult specimens were collected from intestines three white-nosed coatis ( N. narica ), whereas cystacanths (larval form) found in body cavities two amphibian species (paratenic hosts) localities northern southeastern Mexico. Morphologically, both stages identified O. luehei (Travassos,...
Members of the genus Strigea Abildgaard, 1790 are endoparasites birds distributed worldwide. Adults an undescribed species were collected from intestines two hawk (Rupornis magnirostris and Accipiter coperii). Other identified as Parastrigea macrobursa that described in Argentina also recovered (Buteogallus urubitinga Buteogallus anthracinus) three localities along coasts Mexico. Specimens sequenced for molecular markers, internal transcribed spacers locus (ITS1-5.8S rDNA- ITS2) domains...
Abstract Polymorphidae is a monophyletic group of acanthocephalans distributed worldwide. Within this family, Hexaglandula corynosoma specialist species that uses single bird as definitive host. Southwellina hispida generalist broad spectrum hosts to complete its life cycle. In the current research, sequences cytochrome c oxidase subunit 1 ( cox1 ) from mitochondrial DNA were generated 44 specimens H. and 76 S. sympatrically in 6 biogeographic provinces Mexico with objective characterizing...
Adults of the genus
Scaphanocephalus is a small trematode genus belonging to the family Opistorchiidae. The currently contains only three species associated with marine fish as intermediate hosts and fish-eating birds definitive hosts. Here, specimens of were collected from Osprey, Pandion haliaetus, White mullet, Mugil curema in Yucatán Peninsula, Mexico. We report for first-time DNA sequences adult Scaphanocephalus, particularly S. expansus, well sequence different sampled metacercaria. Morphological...
Abstract The taxonomy of the 10 recognized Neoechinorhynchus species associated with emydid turtles is complex due to morphological conservatism. In present study, specimens N. emyditoides from northern and southeastern Mexico exhibit great phenotypic plasticity on its diagnostic characteristics. We sequenced three molecular markers: internal transcribed spacers ITS1, ITS2 5.8S gene, D2 + D3 domains large subunit nuclear DNA cytochrome c oxidase I ( cox1 ) mitochondrial DNA. Sequences...
Abstract A new species of the genus Lyperosomum Looss, 1899, from intestine golden-fronted woodpecker ( Melanerpes aurifrons ) northern Mexico is described. cuauhxinqui sp. n. morphologically distinguished other congeneric Americas by a higher oral/ventral sucker ratio and its body length width. The sequences domains D1–D3 large subunit (LSU) nuclear ribosomal DNA cytochrome c oxidase 1 cox mitochondrial were obtained compared with available GenBank. genetic divergence estimated between...
Abstract Saccocoelioides is a genus of trematodes associated with fishes from the Americas. In current research, morphologically distinct specimens spp. were collected six countries in Middle America. Specimens sequenced using three molecular markers, domains D1–D3 large subunit (LSU) nuclear rDNA, cytochrome c oxidase 1 ( cox1 ) and nicotinamide adenine dinucleotide dehydrogenase nad1 mitochondrial DNA. A total 74 new sequences compared aligned other available GenBank. Maximum likelihood...
Los miembros del género Clinostomum, son un grupo de parásitos que en estadio adulto residen la cavidad bucal aves ictiófagas, mientras fase larva conocida como metacercaria, se encuentran forma quiste color amarillo músculo, oral, ojos, branquias, tejido subcutáneo, gónadas, hígado y otros órganos, peces vida silvestre cultivados distribuidos todo el mundo. En presente proyecto investigación recopilamos información disponible base datos GenBank las especies Clinostomum diferentes regiones...
Adult specimens of Andracantha gravida (Alegret, 1941) were recorded from the intestines double-crested cormorant Nannopterum auritus (Lesson) (type host) and brown pelican Pelecanus occidentalis L. in two localities Mexico: Celestún, Yucatan (south-eastern) Punta Piedra, Tamaulipas (north-eastern). The A. are morphologically characterized by having a pipe-shaped body without swellings, absence small trunk spines between fields on foretrunk cylindrical proboscis with 14-16 rows 10-12 hooks...
Abstract Members of the genus Maritrema Nicoll, 1907 include endoparasites aquatic birds and mammals, distributed worldwide. Adult specimens were collected from intestines three bird species (the great black hawks, Buteogallus urubitinga Gmelin; laughing gull, Leucophaeus atricilla Linnaeus; willet, Tringa semipalmata Gmelin) in localities along Gulf Mexico. Photogenophores sequenced for large subunit (LSU) nuclear rDNA, new sequences aligned with other microphalloid available GenBank. The...
