Relationships of bunyamwera group viruses by neutralization. 1979

A R Hunt, and C H Calisher

A standardized serum dilution plaque reduction neutralization test was used for cross-neutralization studies of 23 strains of Bunyamwera serogroup viruses. Antigenic relationships were determined by inspection of the neutralization tests results as well as by numerical taxonomic analysis. Based on these analyses five complexes, containing 1-11 viruses, were distinguished. Little or no cross-reactivity was observed between viruses of different complexes. Three of the viruses tested were indistinguishable from prototypes and probably represent strains or varieties of those prototypes. A tentative classification scheme for the Bunyamwera group is presented.

UI	MeSH Term	Description	Entries
D009500	Neutralization Tests	The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).

D010948	Viral Plaque Assay	Method for measuring viral infectivity and multiplication in CULTURED CELLS. Clear lysed areas or plaques develop as the VIRAL PARTICLES are released from the infected cells during incubation. With some VIRUSES, the cells are killed by a cytopathic effect; with others, the infected cells are not killed but can be detected by their hemadsorptive ability. Sometimes the plaque cells contain VIRAL ANTIGENS which can be measured by IMMUNOFLUORESCENCE.

D002042	Bunyamwera virus	A species in the ORTHOBUNYAVIRUS genus of the family BUNYAVIRIDAE. A large number of serotypes or strains exist in many parts of the world. They are transmitted by mosquitoes and infect humans in some areas.	Batai virus,Cache Valley virus,Calovo virus,Chittoor virus,Bunyamwera Group Viruses

D001103	Arboviruses	Arthropod-borne viruses. A non-taxonomic designation for viruses that can replicate in both vertebrate hosts and arthropod vectors. Included are some members of the following families: ARENAVIRIDAE; BUNYAVIRIDAE; REOVIRIDAE; TOGAVIRIDAE; and FLAVIVIRIDAE.
