Intestinal helminth fauna of the South American sea lion Otaria flavescens and fur seal Arctocephalus australis from northern Patagonia, Argentina
TLDR
Sea lions and furs seals from northern Patagonia harbour the intestinal helminth communities that could be predicted for otariids, i.e. the combination of species of the genera Corynosoma, Diphyllobothrium, Pseudoterranova, Contracaecum and, in pups, Uncinaria. Expand
High morphological plasticity and global geographical distribution of the Pacific broad tapeworm Adenocephalus pacificus (syn. Diphyllobothrium pacificum): molecular and morphological survey.
TLDR
Phylogenetic analyses based on newly characterised sequences of mitochondrial cytochrome c oxidase subunit 1 and nuclear large subunit ribosomal RNA genes consistently reveal Adenocephalus pacificus as a sister lineage to the clade formed of the remaining Diphyllobothrium species and other genera (Digramma, Diplogonoporus, Ligula). Expand
Assessing host–parasite specificity through coprological analysis: a case study with species of Corynosoma (Acanthocephala: Polymorphidae) from marine mammals
TLDR
Results suggest that both acanthocephalans contact sea lions and franciscanas regularly, however, C. cetaceum cannot apparently reproduce, nor even grow, in Franciscanas and sea lions, respectively. Expand
From mammals back to birds: Host-switch of the acanthocephalan Corynosoma australe from pinnipeds to the Magellanic penguin Spheniscus magellanicus
TLDR
The occurrence of reproductive individuals of C. australe in Magellanic penguins could be interpreted as an adaptive colonization of a novel avian host through favourable mutations, and could also be considered as an example of ecological fitting through the use of a plesimorphic (host) resource. Expand
A checklist of the helminth parasites of marine mammals from Argentina.
TLDR
G gaps in the knowledge of their taxonomic identification, composition, distribution, host specificity and life cycles were revealed in the data compiled on the helminth of marine mammals from Argentina. Expand
A New Species of Ascocotyle (Trematoda: Heterophyidae) from the South American Sea Lion, Otaria flavescens, Off Patagonia, Argentina
TLDR
A new heterophyid species is described based on specimens collected from the intestines of the South American sea lion Otaria flavescens from Patagonia (Argentina), which is the first species of the subgenus Ascocotyle described from a marine mammal. Expand
Novel morphological and molecular data for Corynosoma hannae Zdzitowiecki, 1984 (Acanthocephala: Polymorphidae) from teleosts, fish-eating birds and pinnipeds from New Zealand.
TLDR
Phylogenetic analyses of the newly-generated sequences and for available cox1 sequences revealed a close relationship between C. hannae and C. australe Johnston, 1937, both species infecting pinnipeds in the Southern Hemisphere. Expand
Patterns of trunk spine growth in two congeneric species of acanthocephalan: investment in attachment may differ between sexes and species
TLDR
Invest strategies on attachment may differ, not only between congeneric species of acanthocephalan, but also between sexes of the same species. Expand
Morphological and molecular analyses of a new species of Saccocoelioides Szidat, 1954 (Haploporidae Nicoll, 1914) in the fat sleeper Dormitator maculatus (Bloch) (Perciformes: Eleotridae) from the
TLDR
This is the third species of Saccocoelioides described in Mexico, and the 17th species from the Americas, and it is revealed that S. olmecae n. Expand
A New Species of Empruthotrema (Monogenea: Monocotylidae) from Pteromylaeus bovinus (Myliobatidae) from the Western Mediterranean
TLDR
Emputhotrema chisholmae is the first species of the genus reported from the Mediterranean and differs from the other species by the following combination of features: haptor with 13 marginal loculi, the presence of eyespots, the absence of an accessory piece associated with the male copulatory organ, and a long egg appendage.
