| limited genetic diversity among sarcocystis neurona strains infecting southern sea otters precludes distinction between marine and terrestrial isolates. | sarcocystis neurona is an apicomplexan parasite identified as a cause of fatal neurological disease in the threatened southern sea otter (enhydra lutris nereis). in an effort to characterize virulent s. neurona strains circulating in the marine ecosystem, this study developed a range of markers relevant for molecular genotyping. highly conserved sequences within the 18s ribosomal gene array, the plastid-encoded rna polymerase (rpob) and the cytochrome c oxidase subunit 1 mitochondrial gene (co1) ... | 2010 | 20071081 |
