| bronchoalveolar lavage and pulmonary histopathology in harp seals (phoca groenlandica) experimentally infected with otostrongylus circumlitus. | the objective of this study was to characterize pathologic changes associated with experimental infection of harp seals (phoca groenlandica) with the lungworm otostrongylus circumlitus (metastrongyloidea: crenosomatidae). the leukocyte differential cell count in samples obtained by unguided bronchoalveolar lavage (bal) and the intensity of the histologic lesions in the lungs were assessed in seven harp seals experimentally exposed to 300 infective, third-stage o. circumlitus larvae. seven unexpo ... | 2010 | 20688634 |
