Serovar Tsaratsovo

Tsaratsovo B 81/7 1982

The strains B 52 and B 81 were isolated from harvest mice (Micromys minutus), in the Plovdiv district of Bulgaria by Ivanov in 1962. They were considered to constitute a new serovar named tsaratsovo with type strain B 52 (Manev, 1974 1975). However during further studies by Manev and others on subcultures and cloned cultures of the strain B 52, it was found that it changed its characteristics and appeared to be identical to these of serovar mozdok (Manev, 1982). The strain B 81 and its clone B 81/7 received by Bakoss, kept the original described antigenic characteristics.
Manev therefore proposed to consider the well studied clone B 81/7 as the new type strain of the tsaratsovo serovar (1982). Using the monoclonal antibody technique, Terpstra et al. (1987) considered the strain to represent a separate serovar. However, Hathaway et al. (1985), using cross-agglutinin absorption and restriction endonuclease analysis, did not reveal sufficient differences between the serovars tsaratsovo and mozdok. Therefore the strain is listed as giving controversial typing results (++) (Kmety & Dikken, 1988).
