| | | In complement-fixation tests performed in Vellore, non-reactive with hyperimmune mouse sera to: group A virus, Sindbis; group B viruses, dengue, Japanese, encephalitis, West Nile; other arboviruses including Chittoor (Bunyamwera), Sathuperi (Simbu) and Umbre (Turlock); other agents isolated previously in Vellore and believed to be arboviruses though not at the time identified or grouped; and to the LGV- ornithosis viruses. Reactive with hyperimmune mouse sera to other strains of same agent. | | At the Yale Arbovirus Research Unit (YARU), the Thimiri virus (I66414) was found to be closely related or identical by CF and NT to viruses isolated in Egypt from a Sylvia communis in 1963 (EgAn 6165) and from a Sylvia curraca in 1966 (EgAn 890-3). The EgAn 890-3 strain reacted by CF with Simbu grouping ascitic fluid and not with 16 other grouping fluids. A Serum of EgAn 890-3 with homologous titer of 1024 reacted to 16 with Buttonwillow, to 32 with Oropouche and to 8 with Simbu antigens and was negative with 6 others, indicating that the relationship by CF to the Simbu group viruses was definite [4] . | | Results of cross-neutralization comparisons of Simbu group viruses place Thimiri virus in the Thimiri complex within the Simbu serogroup [6] . | | |
