Abstract
The specificity of lethal infection was studied in noninbred white mice (age - 15 to 20 and 25 to 30 days) infected intraperitoneally with the EP-2 strain of cowpox virus (CPV) in doses 10s, 106 and 107 PFU. The virus caused the lethal infection in the 15-20-day mice; while the 25-30-day mice remained healthy and survived. Virologic, immunologic-and-histochemical and electron-microscopy examinations of the 15-20-day mice revealed a replication of the EP-2 strain in tissues bordering on the virus introduction area; there was no generalization of infection. The virus replicated first in the mesothelium cells, and after that, in fibroblasts as well as in the endothelial, fatty, adventicial, cross-striated and muscle cells and in myosatellites.
