[Herpes virus isolated from pigeons (author's transl)].

A virus has been isolated from pigeons with the clinical symptoms of "infectious coryza". The virus produces numerous pocks on the chorio-allantoic membranes; livers from infected embryos have areas of necrosis. Microscopic examinations reveals basophilic and eosinophilic intranuclear inclusions. The virus produces a cytopathic effect of rounded refractile cells after 24 h with rapidly spreads throughout the monolayer. The virus is sensitive to chloroform. Electron microscopy of negatively stained lysed cell preparations shows that the virus is a herpesvirus. The strain is pathogenic for pigeons. Lesions produced by intralaryngeal inoculation consists of small necrotic foci in the laryngeal epithelium and in the liver.
