Electron microscopic study of virus infections in the erythrocytes of the frog Ptychadena anchjetae from northern Transvaal, South Africa revealed icosahedral iridovirus-like particles measuring 175 to 198 nm in diameter. containing a dense, pleomorphic nucleoid. Virions were enveloped by 2 membranes, and may be associated with extensive membranous clots. The virus assembled in the cytoplasm within spherical fibrillar virosomes. Infected cells contained a large crystalloid inclusion body in
