Austrodiplostomum ostrowskiae n. sp. (Digenea: Diplostomidae: Diplostominae) from the Double-crested Cormorant, Phalacrocorax auritus (Phalacrocoracidae) from the Galveston, Texas Area of the Gulf of Mexico, U.S.A.

The influence of geographical location, host maturity and sex on intestinal helminth communities of the double-crested cormorantPhalacrocorax auritusfrom the eastern United States

“…This is the first study to document the intestinal parasite infracommunities of P. auritus collected from multiple localities within the eastern US. We report infections as previously observed in P. auritus and other cormorant species near sampling regions in this study (Dubois & Mahon, 1959; Hutton & Sogandares-Bernal, 1960; Hutton, 1964; Threlfall, 1982; Chandler & Rausch, 1984; Kuiken et al , 1999; Overstreet & Curran, 2004, Robinson et al , 2008, 2009; Doffitt et al , 2009; Dronen, 2009; Violante-Gonzalez et al , 2011; Garcia-Varela et al , 2012; Wagner et al , 2012; O'Hear et al , 2014; Kudlai et al , 2015) and confirm the widespread distribution of many parasites of this host. In particular, D. auritus occurred in all locations sampled in this study, consistent with high prevalence values reported in Robinson et al (2010) and Wagner et al (2012).…”

“…Many studies have documented the intestinal parasites of P. auritus at single locations or within a narrow region of its distribution, often focusing on a particular parasite taxon (Hutton, 1964; Threlfall, 1982; Flowers et al , 2004; Dronen, 2009; Wagner et al , 2012). This is the first study to document the intestinal parasite infracommunities of P. auritus collected from multiple localities within the eastern US.…”

Parasite assemblages of Double-crested Cormorants as indicators of host populations and migration behavior

“…Acanthocephalan prevalence was highest in the east. The prevalences reported here are comparable to those of cormorants in Florida (Hutton and Sogandares-Bernal, 1960;Hutton, 1964;Threlfall, 1982), Texas (Dronen, 2009), Mississippi (Overstreet and Curran, 2004;Doffitt et al, 11 2009, O'Hear et al, 2014, central Canada (Chandler and Rausch, 1984;Kuiken et al, 1999;Robinson et al, 2008;Robinson et al, 2009;Wagner et al, 2012), and Mexico (Violante-Gonzalez et al, 2011;Garcia-Varela et al, 2012; see data imbedded in Supplemental Interactive Map and Table S.3). Because individual parasite species exhibit geographic gradients, and not all in parallel, the analysis of the parasite assemblage as a whole rather than of any one or few species will best discriminate populations from different sites, regions, or of different migration status.…”

Two New Metacercariae of Genus Austrodiplostomum (Trematoda: Diplostomidae) from Oreochromis niloticus (Cichlidae) and Varicorhinus beso (Cyprinidae) in Tana Lake, Ethiopia

“…Before this study, the genus Austrodiplostomum was represented by three species: A. compactum , A. mordax Szidat et Nani, 1951(Szidat & Nani, 1951, and A. ostrowskiae Dronen, 2009(Dronen, 2009). All of them as adult are endohelminthic parasites of cormorants Szidat & Nani, 1951;Ostrowski de Núñez, 1970;Dubois & Macko, 1972;Nasir & Díaz, 1972;Dubois, 1977;Rietschel & Werding, 1978;Fedynich et al, 1997;Dronen, 2009) and freshwater fishes (Machado et al, 2005;Salgado-Maldonado, 2006;Novaes et al, 2006;Violante-González et al, 2009) (Rosser et al, 2016). As metacercariae the genus Austrodiplostomum was represented by A. compactum Dubois, 1970, A. mordax (Szidat et Nani, 1951) n.…”

“…As metacercariae the genus Austrodiplostomum was represented by A. compactum Dubois, 1970, A. mordax (Szidat et Nani, 1951) n. comb., and A. ostrowskiae Dronen, 2009. These metacercariae are parasites of different South American, Central American and North American freshwater fishes.…”
