Herpesvirus Infections and Treatments

Dogs are a definitive host of Neospora caninum and cattle are intermediate hosts. Alternative life-cycles have not been investigated. Foxes are frequently seropositive, but may not commonly prey upon cattle; therefore, other intermediate hosts may exist that are frequent prey of foxes. Three domestic pigeons (Columbia livia) and three zebra finches (Poephila guttata) were inoculated with N. caninum tachyzoites, to determine if they could serve as intermediate hosts. Tissue culture, PCR, serology, and histology were all positive for one or more pigeons. All finches resisted infection. Further testing of columbiform birds as intermediate hosts of N. caninum is warranted.
