| gastrointestinal helminths of gentoo penguins (pygoscelis papua) from stranger point, 25 de mayo/king george island, antarctica. | the aim of this work is to contribute to the knowledge of gastrointestinal parasites of the gentoo penguin (pygoscelis papua) from 25 de mayo/king george island (south shetlands, antarctica). gastrointestinal tracts of 37 fresh dead individuals (21 chicks, 10 juveniles, and 6 adults) were collected from december 2006 to february 2012 and examined for macroparasites. four adult parasite species were found: one cestoda species (parorchites zederi), two nematoda species (stegophorus macronectes and ... | 2013 | 23435921 |
| mode of attachment and pathology caused by parorchites zederi in three species of penguins: pygoscelis papua, pygoscelis adeliae, and pygoscelis antarctica in antarctica. | we identified and compared gross and microscopic lesions associated with the cestode, parorchites zederi, in the digestive tracts of three species of penguins (spheniscidae): the chinstrap ( pygoscelis antarctica ), gentoo ( pygoscelis papua ), and adélie penguins ( pygoscelis adeliae ). the gastrointestinal tracts of 79 recently dead individuals (71 chicks and eight adults) were collected in locations throughout the antarctic peninsula during summer field trips in 2006-09. parorchites zederi wa ... | 2016 | 27195682 |
