“…Fifty-six acanthocephalan adults and four cystacanths were collected from the 25 positive SAMs. Three adult species of the genus Corynosoma (Lühe 1904), C. obtuscens (Lincicome 1943), C. strumosum (Rudolphi 1802), and C. validum (Van Cleave 1953) and immature specimens of the genus Bolbosoma (Porta 1908) were identified (Fig. 1).…”

Intestines of dead northern fur seals (Callorhinus ursinus) on St. Paul Island (SPI), Alaska were inspected for specific internal parasites (hookworms and acanthocephalans) in July and August, 2007. Pups (n=64) were examined for adult hookworms (Uncinaria lucasi) and four (6.25%) were infected. The number of specimens per infected pup was 1, 2, 2, or 408. Low prevalence was similar to that determined in the last investigation (2001) in dead fur seal pups on SPI by two of the present authors (Lyons and Spraker). Subadult males (SAMS-3-4 years old, n=115) were examined for acanthocephalans and 25 (21.7.0%) were infected. Adult Corynosoma (C. obtuscens, C. strumosum, and C. validum) (n=56) and immature Bolbosoma spp. (n=4) were found. Apparently, this is a new host record for C. obtuscens and C. validum. Notes were made on finding tapeworms. in 114 of the 115 SAMs. Examination of some specimens revealed scolices characteristic of Diphyllobothrium spp.

“…A total of 2,268 specimens of acanthocephalans representing fi ve species from three genera of the family Polymorphidae Meyer, 1931: Andracantha phalacrocoracis (Yamaguti, 1939) Schmidt, 1975, Andracantha sp., Corynosoma strumosum (Rudolphi, 1802), C. obtuscens Lincicome, 1943 and Profi licollis altmani (Perry, 1942), were collected. Prevalence and intensity of infections with separate species of acanthocephalans varied widely between sea lions of diff erent age groups (table 1).…”

“…Specimens intended for morphological analysis were mounted in Berlese's medium and examined under light microscope Zeiss Axio Imager M1. Specimens were identifi ed on the basis of their morphology using descriptions by Perry (1942), Lincicome (1943), Van Cleave (1953 a), Petrochenko (1958), Golvan (1959). Photomicrographs were made from a representative specimen of each species with a digital camera mounted on Zeiss Axio Imager M1 microscope.…”

“…However, not many studies on helminths parasitizing California sea lions have been performed and published (Lincicom, 1943;Dailey, 1969;Dailey & Hill, 1970;Lyons et al, 1997Lyons et al, , 2001Lyons et al, , 2005Kuzmina & Kuzmin, 2015). To date, eleven helminth species including fi ve species of nematodes from the genera Acanthocheilonema Cobbold, 1870, Anisakis Dujardin, 1845, Contracaecum Mozgovoi et Shakhmatova, 1971, Parafi laroides Dougherty, 1946and Uncinaria Frölich, 1789; one species of cestodes from the genus Diphyllobothrium Cobbold, 1858; three species of trematodes from the genera Pricetrema Ciurea, 1933, Stictodora Looss, 1899and Zalophotrema Stunkard et Alvey, 1929; and two species of acanthocephalans from the genus Corynosoma Lühe, 1904 have been reported from California sea lions (Lincicome, 1943;Van Cleave, 1953 a, b;Delyamure, 1955;Dailey & Hill, 1970;Dailey & Brownell, 1972). Acanthocephalans were found in California sea lions twice; the fi rst report documenting acanthocephalans from California sea lions was p ublished by Lincicome (1943), who reported two species, Corynosoma osmeri Fujita, 1921 andC.…”

To increase the currently limited knowledge addressing acanthocephalans parasitizing California sea lions (Zalophus californianus), 33 animals including pups, juvenile and adult males and females from the Marine Mammal Center (TMMC), Sausalito, California, USA were examined. Totally, 2,268 specimens of acanthocephalans representing five species from the genera Andracantha (A. phalacrocoracis and Andracantha sp.), Corynosoma (C. strumosum and C. obtuscens) and Profilicollis (P. altmani) were found. Profilicollis altmani and A. phalacrocoracis, predominantly parasitize fish-eating birds; they were registered in Z. californianus for the first time. Prevalence and intensity of California sea lion infection and transmission of acanthocephalans in these hosts of different age groups were analyzed and discussed. We provide brief morphological descriptions of the five species of acanthocephalan found in California sea lions.

Acanthocephalans in northern fur seals (Callorhinus ursinus) and a harbor seal (Phoca vitulina) on St. Paul Island, Alaska: species, prevalence, and biodiversity in four fur seal subpopulations

et al. 2012

Monitoring studies of acanthocephalans in northern fur seals (Callorhinus ursinus Linnaeus, 1758) (NFSs) and a harbor seal (Phoca vitulina Linnaeus, 1758) were performed on St. Paul Island, Alaska, in July-August 2011. Gastrointestinal tracts of 105 humanely harvested NFS subadult males (SAMs) (3-4 years old) were collected during the annual Aleut subsistence harvest at four haul-out areas (HOAS): Lukanin (n = 26 NFSs), Polovina (n = 28), Gorbatch (n = 30), and Morzhovyi (n = 21). One gastrointestinal tract collected from a harbor seal (about 3-4 years old) found dead at Morzhovyi HOAS was also examined. The total prevalence of infection in NFSs with acanthocephalans was 29.52 % with variations from 7.69 % to 47.62 % between the four different HOAS. Eight acanthocephalan species of two genera-Corynosoma Lühe, 1904 (Corynosoma strumosum, Corynosoma alaskensis, Corynosoma cameroni, Corynosoma semerme, Corynosoma similis, Corynosoma validum, and Corynosoma villosum), and Bolbosoma Porta, 1908 (Bolbosoma nipponicum)-were found in the NFSs and a harbor seal. This is a new record of C. alaskensis for the NFSs. Short biological notes of the species found are presented. Differences in species composition as well as in prevalence of acanthocephalans parasitizing NFSs were observed in subpopulations from four different HOAS on St. Paul Island. The highest biodiversity of acanthocephalans and infection were found in subpopulations on Polovina and Morzhovyj HOAS, the lowest was on Lukanin HOAS. From 3.2 % (for C. validum) to 19.4 % (for C. villosum) of NFSs were infected by one acanthocephalan species; two species were found in 22.6 %; three in 9.7 %; and four in 3.2 %. Further studies of NFS parasites are necessary to follow the trends in parasitic infection rates and diversity in NFS population on the Pribilov Islands and for monitoring the influence of various ecological factors on NFS populations in Alaska.
