Some investigations on Newcastle disease in Egyptian ostriches (Struthio camelus).

摘要

During late autumn and winter (December 2004-February 2005), four ostrich farms around Egypt were surveyed and samples from 54 clinically diseased and fresh dead birds were collected and tested for detection and determination of the incidence, course, clinical signs, postmortem and histopathological findings and the pathogenicity of NDV among ostriches (Struthio camelus). Two NDV isolates were detected, propagated in chicken embryos, pathotyped and examined by EM. HI was adopted for the detection and quantification of antibodies to NDV..
