Grippotyphosa Moskva V 1928
Tarassov and Epstein isolated strains from patients with "water-fever" in the Moscow region of the Soviet-Union, studied them serologically and denominated them as L. grippotyphosa. No names of strains are mentioned in the original paper (Tarassov, Epstein, 1928).
According to Chernukha (personal communication), Terskikh isolated in 1929 a strain from a patient which was sent to Amsterdam under the designation "Moskva Y". The strain was studied by Dinger (1930), who found it serologically distinct from Icterohaemorrhagiae and other strains. This is apparently the strain known today as Moskva V. It is considered to be the reference strain of serovar Grippotyphosa.
The strain was later submitted to factor analysis (Kmety, Lataste-Dorolle, 1973), which revealed its antigenic structure.
Using monoclonal antibodies strains of this serovar can be further subdivided (Kmety et al. and Ananyina et al., Leptospirosis Research Conference Moskou, 1991).
Based on various differences described by Wolff and Bohlander, 1952, Steinen et al., 1992 and Hartskeerl et al., 2004, the serovar Grippotyphosa have been divided into two types, i.e. Grippotyphosa type Moskva and Grippotypohosa type Duyster (Hartskeerl et al., 2004). This division in types has been recognized by the Subcommittee on the taxonomy of Leptospiraceae, in the meeting of 18 September 2007 in Quito (TSC, 2008).
It should be noted that according to the current criteria that define a separate serovar (TSC 1987), the serovars Grippotyphosa, Ratnapura, Valbuzzi and Muelleri actually consist of a single serovar (Hartskeerl et al., 2004)
