Review
DNA of human cytomegalovirus (HCMV) contains three transforming fragments, which have been mapped in the long unique region of the viral genome(see Fig.1). A minimal region of 558 base pairs(bp) (pCM4127) was localized in the XbaI-Hindlll fragment of HCMV strain AD169 (mapunit 0.123—0.140)and ..., Abstract

Review
Chinese tupaia belangeri yunalises were infected with Russian spring summer encephalitis viruses (Dongbai, YH, T57 strains) by intracerebral, intraperitoneal and subcataneous route. All tupaia belangeri yunalies had viremia and lasted for 7—9 days. Immune response depended on pathogen which light ..., Abstract

Review
Vulvar biopsy specimens from nine patients with vulvar dystrophy were examined for the presence of human papillomavirus DNA by Southern blot hybridization. The results showed that two of eight hypcrplastic dystrophies contained HPV 16 homologous sequence, one contained HPV 33 homologous sequence ..., Abstract

Review
The inactivated EHF vaccine was used inclinincal trial with 75 volunteers. There was not any side effects. It showed that abaut 90% seroconversion rate of neutraliztion antibody occurred. The vaccine stored for 14 months in 4℃ still had better immunogenicity. It was shown for the second time that ..., Abstract

Review
Dot hybridization assay was developed to detect epidemic hemorrhagic fever virus(EHFV)RNA genome using probe which biotin-7-dATP labeled R-3 cDNA clone of M fragement of EHFV R-22 strain. This probe was used to detect RNA genome of the human original EHFV H-114 and H-435 strains in cell cultures. ..., Abstract

Review
Using PAGE method, we analysed genomic RNA patterns of several standard strains of rotavirus including Wa, Ito, Yo Hochi, ST, SA-11 and UK strains, and the epidemic strains of rotavirus which caused infant diarrhoea in Nanjing in October to December 1989. It was interesting that the electrophoretic ..., Abstract

Review
The larvae of Ostrinia furnacalis are susceptible to the infection with the nuclear polyhedrosis virus of Plusia agnata(PaNPV), the Antheraea pernyi NPV (ApNPV)and the cytoplasmic polyhedrosis virus of Dendrolimus spectabilis(DsCPV). The ID_50 for the 1st instar larvae infected with DsCPV is ..., Abstract

Review
Narcissus mosaic virus(NMV) was obtained from the mixed infected narcissus plants and purified from the inoculated leaves of Chenopodium amarnticolor. The procedures of purification involved precipitation with 6% PEG ( M. W. 6000 ), differential centrifugation and 20—50% sucrose density-gradient ..., Abstract

Review
The hybridoma cell lines secreting monoclonal antibodies to Potato Leafroll Virus (PLRV) were established by fusion of myeloma cells SP2/0 with spleen cells of BALB/C mouse immunized with purified PLRV by direct spleen injection followed by two tail injections. The hybridoma were screened ..., Abstract

Review
The isolated strawberry pseudo-mild yellow edge virus(SPMYEV)was maintained in the strawberry-Fragaria vesca L.var. UC-4, and was successfully extracted and purified through homogenization by polyethyleneglycol (PEG) precipitation, differential centrifugation in the sucrose cushion and continuous ..., Abstract

Review
Eight common fishes were infected with grass carp hemorrhage virus (GCHV)that was from sick grass carp with hemorrhage symptom. ELISA detection showed that artificially infected black carp, silver carp and Hemiculter bleekeri blcckeri were positive, and then carp, variegated carp, triangular bream ..., Abstract
