the lungworm, halocercus spp. (nematoda: pseudaliidae) in cetaceans from california.three cetaceans from monterey bay, california (usa), were infected with lung nematodes. a beaked whale calf, mesoplodon sp. was infected with adult halocercus sp. this represents a new host record for this nematode. the lungs of a northern right whale dolphin calf, lissodelphis borealis, contained an unidentified nematode similar in size to halocercus sp. the presence of phyllobothrium delphini-type cestode larvae in its blubber is evidence that the calf was feeding on invertebrates. a pregnant ...19938355360
molecular phylogenetics and diagnosis of anisakis, pseudoterranova, and contracaecum from northern pacific marine mammals.individual specimens of anisakis, pseudoterranova, and contracaecum collected from marine mammals inhabiting northern pacific waters were used for comparative diagnostic and molecular phylogenetic analyses. forty-eight new sequences were obtained for this study of 14 anisakis taxa, 8 pseudoterranova taxa, 4 contracaecum taxa, and 4 outgroup species. partial 28s (lsu) and complete internal transcribed spacer (its-1, 5.8s, its-2) ribosomal dna was amplified by the polymerase chain reaction and seq ...200516539026
campylobacter insulaenigrae isolates from northern elephant seals (mirounga angustirostris) in california.there are only two reports in the literature demonstrating the presence of campylobacter spp. in marine mammals. one report describes the isolation of a new species, campylobacter insulaenigrae sp. nov., from three harbor seals (phoca vitulina) and a harbor porpoise (phocoena phocoena) in scotland, and the other describes the isolation of campylobacter jejuni, campylobacter lari, and an unknown campylobacter species from northern elephant seals (mirounga angustirostris) in california. in this st ...200717259365
molecular characterization of sarcocystis neurona strains from opossums (didelphis virginiana) and intermediate hosts from central california.sarcocystis neurona is a significant cause of neurological disease in horses and other animals, including the threatened southern sea otter (enhydra lutris nereis). opossums (didelphis virginiana), the only known definitive hosts for s. neurona in north america, are an introduced species in california. s. neurona dna isolated from sporocysts and/or infected tissues of 10 opossums, 6 horses, 1 cat, 23 southern sea otters, and 1 harbor porpoise (phocoena phocoena) with natural infections was analy ...201020226596
the distribution of 4-nonylphenol in marine organisms of north american pacific coast of the chemical breakdown products of nonylphenol ethoxylates, 4-nonylphenol (4-np), accumulates in organisms and is of concern as an environmental pollutant due to its endocrine disrupting effects. we measured 4-np levels in the seawater, sediment, and twelve organisms within the california estuary, morro bay, and examined biomagnification of 4-np using stable isotope abundances (δ(15)n and δ(13)c) to quantify trophic position. 4-np concentrations in organisms from morro bay included 25000± ...201222257992
