Inclusion Body--An Important Morphological Marker of Infectious canine hepatitis virus

Morphological characterization of Infectious canine hepatitis virus specific inclusion bodies was carried out by both immunogold electron microscopy and electron microscopy in sire hybridization． Three morphological types of inclusion bodies were observed：loose homogeneous，paracrystalline an d dense gran ular inclusion body．The former two labelled with immunogold are viral an tigenic protein of viral particles，the latter one labelled with viral DNA probe is composed of viral DNA．Th e possible relationship among the inclusion bodies an d their be aring to virus morphogenesis were discussed
