“…However, the molecular data presented by Chilton et al (2006) provide strong evidence for their inclusion in the Metastrongylina, potentially as a superfamily distinct from the Metastrongyloidea. A more recent molecular study of a limited number of taxa by Lehnert et al (2010) confirmed the position of the Dictyocaulidae as a sister group to the remaining metastrongyloids and suggested that the Pseudaliidae might be paraphyletic.

“…Pinnipeds are infected with lungworms by consumption of intermediate host fish species. Parafilaroides decorus in the California sea lion uses a tide pool fish ( Girella nigricans ) as an intermediate vertebrate host [145,146], whereas P. gymnurus larvae and Pseudalius inflexus were isolated from plaice (Platessa pleuronectes ) and dab ( Limanda limanda ) [147]. Whether the Brucella infection originates from fish or from fish parasites is unknown and warrants further investigation.…”

Brucella spp. were isolated from marine mammals for the first time in 1994. Two novel species were later included in the genus; Brucella ceti and Brucella pinnipedialis, with cetaceans and seals as their preferred hosts, respectively. Brucella spp. have since been isolated from a variety of marine mammals. Pathological changes, including lesions of the reproductive organs and associated abortions, have only been registered in cetaceans. The zoonotic potential differs among the marine mammal Brucella strains. Many techniques, both classical typing and molecular microbiology, have been utilised for characterisation of the marine mammal Brucella spp. and the change from the band-based approaches to the sequence-based approaches has greatly increased our knowledge about these strains. Several clusters have been identified within the B. ceti and B. pinnipedialis species, and multiple studies have shown that the hooded seal isolates differ from other pinniped isolates. We describe how different molecular methods have contributed to species identification and differentiation of B. ceti and B. pinnipedialis, with special emphasis on the hooded seal isolates. We further discuss the potential role of B. pinnipedialis for the declining Northwest Atlantic hooded seal population.

“…In the German Wadden Sea, the most common parasites infecting the respiratory tract of harbor seals are two species of metastrongyloid nematodes ( Otostrongylus circumlitus , Crenosomatidae and Parafilaroides gymnurus , Filaroididae ) (Lehnert et al . , , Rijks et al . ).…”

The stable isotope composition (d N compared to foraging seals. We studied the temporal variation of stable isotope composition of young-of-the-year and adults to determine from which point in time the young-of-the-year tissues (i.e., muscles and vibrissae) are influenced by independent foraging only. These results were compared with the development of trophically transmitted parasitic infections. The d 15 N values in young-of-the-year muscles decreased from June (20.3& AE 0.5&) to October (18.5& AE 0.4&), while those of foraging seals were all year long below 19.2&. This decrease coincides with the increase of parasitic infections in young-of-the-year, reflecting a shift to fish diet. Together these results suggest that the muscles of the young-of-the-year older than 5-6 mo reflect independent foraging and that they can therefore be used in community diet studies. The nursing signal in vibrissae was unclear, as the d 15N values of young-of-the-year were stable over time, whereas those of adults varied seasonally. However, d15 N values of nursing pups were significantly higher than those of adults in May and June, maybe due to their reliance on milk.
