[Morphological study of Omsk hemorrhagic fever (OHF) virus with the electron microscope].

Morphological characterization of OHF virus was studied by means of thin section electron microscopy in the brains of mice infected with Omsk hemorrhagic fever virus. The crystals, microvesicles, vacuoles and as beehive structures were observed in the virus-infected cells. The possible relationship between the characteristic structures and virus morphogenesis is discussed. It is indicated that these characteristic structures may be important to morphological characterization of OHF virus.
