Isolation and Some Properties of Periplaneta fuliginosa Virus
Abstract: Recently, we isolated a non-occluded virus from spontaneous mortal Periplaneta fuliginosa(Serville). The virus suspension was mixed in sterile food to feed healthy P. fuliginosa nymphs(of 154—169 days). The percent mortality of the nymphs which died with infected virus was over 98%. Under electronmicroscope the virus was isometric particle about 23nm in diameter. The ultraviolet absorption of the virus was as character as nucleoprotein Purified virus suspension was used to distinguish the nucleic acid kinds...
