| observations on the infectivity of parasitic third-stage larvae of uncinaria lucasi stiles 1901 (nematoda: ancylostomatidae) of northern fur seals, callorhinus ursinus linn., on st. paul island, alaska. | twelve fur seal pups, which had not nursed their mothers, were used in an infectivity experiment. pups were exposed to parasitic 3rd-stage larvae of uncinaria lucasi from belly tissues of fur seal bulls, bachelors, and pregnant cows, to determine maturation capability of the larvae. hookworms were not recovered from the intestines of 3 pups receiving larvae from belly blubber of bulls, 6 pups receiving larvae from belly blubber of bachelors, and 1 nonexposed pup. maturation of hookworms did occu ... | 1978 | 149188 |
| historic importance of some aspects of research by o. wilford olsen on hookworms (uncinaria lucasi) in northern fur seals (callorhinus ursinus) and steller sea lions (eumatopias jubatus) in 1951 on st. paul island, alaska. | the purpose of this paper is to disseminate, more widely, certain historically important aspects of research by o. wilford olsen on hookworms (uncinaria lucasi) in northern fur seals (callorhinus ursinus) and steller sea lions (eumatopias jubatus) in 1951 on st. paul island, alaska. highly meaningful facets of the research were recorded only in a report with limited availability by olsen in 1952. portions of his research presented here include measurements of hookworm free-living infective third ... | 2005 | 15719260 |
| 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 |
