first report and characterization of adult uncinaria spp. in new zealand sea lion (phocarctos hookeri) pups from the auckland islands, new zealand. | two species of hookworms (uncinaria lucasi and uncinaria hamiltoni) have been formally described from pinnipeds, but dissimilar types are noted from these hosts. this report is the first description of hookworms (uncinaria spp.) from the new zealand sea lion, phocarctos hookeri. the nematodes were collected from dead pups on enderby island (auckland islands, 50 degrees 30', 166 degrees 17') during january and february, 2004. standard measurements of male and female hookworms were obtained, provi ... | 2006 | 16362338 |
intestinal helminth fauna of the south american sea lion otaria flavescens and fur seal arctocephalus australis from northern patagonia, argentina. | we report on the intestinal helminth fauna of 56 south american sea lions, otaria flavescens, and 5 south american fur seals, arctocephalus australis, from northern patagonia, argentina. a total of 97,325 helminth specimens were collected from sea lions. gravid individuals were represented by 6 species of parasites: 1 digenean (ascocotyle (ascocotyle) patagoniensis), 1 cestode (diphyllobothrium spp.), 3 nematodes (uncinaria hamiltoni, contracaecum ogmorhini s.s., pseudoterranova cattani) and 1 a ... | 2013 | 22967801 |
uncinaria sanguinis sp. n. (nematoda: ancylostomatidae) from the endangered australian sea lion, neophoca cinerea (carnivora: otariidae). | this study investigates the identity of hookworms parasitising the australian sea lion, neophoca cinerea (péron), from three colonies in south australia, australia. the australian sea lion is at risk of extinction because its population is small and genetically fragmented. using morphological and molecular techniques, we describe a single novel species, uncinaria sanguinis sp. n. (nematoda: ancylostomatidae). the new species is most similar to hookworms also parasitic in otariid hosts, uncinaria ... | 2014 | 25065131 |
molecular systematics of pinniped hookworms (nematoda: uncinaria): species delimitation, host associations and host-induced morphometric variation. | hookworms of the genus uncinaria have been widely reported from juvenile pinnipeds, however investigations of their systematics has been limited, with only two species described, uncinaria lucasi from northern fur seals (callorhinus ursinus) and uncinaria hamiltoni from south american sea lions (otaria flavescens). hookworms were sampled from these hosts and seven additional species including steller sea lions (eumetopias jubatus), california sea lions (zalophus californianus), south american fu ... | 2013 | 24162075 |
morphometric and molecular characterization of the species of uncinaria frölich, 1789 (nematoda) parasitic in the australian fur seal arctocephalus pusillus doriferus (schreber), with notes on hookworms in three other pinniped hosts. | this study presents morphological and molecular data on hookworms from the australian fur seal arctocephalus pusillus doriferus (schreber) currently identified in australian waters as uncinaria hamiltoni baylis, 1933. additional specimens from the australian sea lion neophoca cinerea (péron) and the new zealand fur seal arctocephalus forsteri (lesson) from australia, and the southern elephant seal mirounga leonina (linnaeus) from antarctica, were included. using the internal transcribed spacer ( ... | 2013 | 23595493 |
uncinaria hamiltoni (nematoda: ancylostomatidae) in south american sea lions, otaria flavescens, from northern patagonia, argentina. | thirty-one south american sea lion pups (otaria flavescens) found dead in punta león, argentina, during the summer of 2002, were examined for hookworms (uncinaria hamiltoni). parasite parameters were analyzed in 2 locations of the rookery, i.e., a traditional, well-structured breeding area and an expanding area with juveniles and a lax social structure. prevalence of hookworms was 50% in both localities, and no difference was observed in prevalence between pup sexes (p > 0.05). hookworms were co ... | 2004 | 15357082 |
