| assessing host-parasite specificity through coprological analysis: a case study with species of corynosoma (acanthocephala: polymorphidae) from marine mammals. | in this paper we report an investigation of the utility of coprological analysis as an alternative technique to study parasite specificity whenever host sampling is problematic; acanthocephalans from marine mammals were used as a model. a total of 252 scats from the south american sea lion, otaria flavescens, and rectal faeces from 43 franciscanas, pontoporia blainvillei, from buenos aires province, were examined for acanthocephalans. specimens of two species, i.e. corynosoma australe and c. cet ... | 2012 | 21554836 |
| 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 |
