Morphological and molecular characterization of a novel eimerian species (Apicomplexa: Eimeriidae) from the Australian pelican Pelecanus conspicillatus Temminck, 1824 (Pelecaniformes: Pelecanidae) in Western Australia

Eimeria erythrorhynchosi n. sp. (Apicomplexa: Eimeriidae) from the American white pelican Pelecanus erythrorhynchos Gmelin, 1789 (Pelecaniformes: Pelecanidae) in Toluca, Mexico

“…from cormorants was reported by Rakhmatullina-Batyrshina and Svanbaev (1972) in Russia. Two Eimeria species, Eimeria pelecani Courtney and Ernst (1975) , and Eimeria briceae Yang et al (2023) , have been reported from the genus Pelecanus in the family Pelecanidae ( Courtney and Ernst, 1975 ; Yang et al, 2023 ). Eimeria erythrorhyncosi can be differentiated from Eimeria pelecani , Eimeria briceae , Eimeria ardae Shamsuddin and Jasim (1980) , and Eimeria auritusi Yabsley, Gottdenker & Fisher, 2002 , by micropyle being present.…”

“…Up to now, two species of Eimeria has been identified in pelicans: Eimeria pelecani in the brown pelican ( P. occidentalis ) in USA ( Courtney and Ernst, 1975 ) and Eimeria briceae in the Australian pelican ( P. conspicillatus ) in Australia ( Yang et al, 2023 ). Hence, the aim of the present study was morphologically characterise the coccidial oocyst found in faeces from AWP.…”
