A Note on Porrocaecum depressum (Zeder, 1800) (Nematoda: Anisakinae)

Helminths ofMilvago chimango temucoensis(Aves: Falconiformes) from Los Ríos Region, Chile: New Records for Neotropical Raptors

“…In comparison to Morgan & Schiller (1950), eggs measurements in the present study were greater to the previously mentioned study, yet other characteristics such as body length, dentigerous ridge in labias, number of pre-cloacal and post-cloacal papillae and similitude of both spicules are coincident for P. depressum. Another species isolated from raptors is Porrocaecum angusticolle Molin 1860 (Scott, 1956;Hartwich, 1979), but this species is smaller and spicules are shorter that P. depressum.…”

“…The mucron as itself is not mentioned in the descriptions of this ascarid. However, in the illustrations of Morgan & Schiller (1950) is evident the presence of the mucron in the posterior end. Such structure was also detected at the posterior end of an adult nematode of Porrocaecum crassum Deslongchamps 1824, from Anas georgica Gmelin 1789 (Anseriformes, Anatidae) (Veterinary Parasitology Laboratory, UACh, unpublished data) in Chile.…”

New Host and Distribution Records for Gastrointestinal Parasites of Raptors from Connecticut, U.S.A

“…Other North American records from this host: Ohio and/or Wisconsin, U.S.A. (Morgan and Schiller, 1950a).…”

“…Additional records from North American raptors: Accipiter cooperii, Florida, U.S.A. (Kinsella et al, 1995); A. striatus, New Jersey (Morgan and Schiller, 1950a), Pennsylvania (Wood, 1931;Morgan and Schiller, 1950a), and South Carolina, U.S.A. (Morgan and Schiller, 1950a); Asio wilsonianus, Wisconsin, U.S.A. (Morgan and Schiller, 1950a); Asio flammeus, Florida, U.S.A. (Leidy, 1886); B. scandiacus, Michigan (Morgan and Schiller, 1950a) Remarks: Although Morgan and Schiller (1950a) listed the states from which they examined raptors for P. depressum, in some cases they did not specify states where infected birds were recorded. Although this species appears to be primarily a parasite of owls judging by prevalence and intensities of infection, it shows little host specificity and has also been recorded from several species of hawks.…”

“…; S. occidentalis, Oregon, U.S.A (Hoberg et al, 1989)(Kinsella et al, 2001), Iowa, Ohio, and/or Wisconsin, U.S.A (Morgan and Schiller, 1950a)(Kinsella et al, 2001)…”
