Sari is one of the strains isolated in 1940 from patients in Nothern Italy by Mino (1941), who considered the mto be closely relate, but not identical to serovar sejroe. Babudieri (1956) studied the strain and described it as a new serovar which he named mini. The strain was submitted to factor analysis by Kmety (1977), who suggested that is should be placed in a new serogroup named Mini. The TSC accepted this suggestion during the Boston meeting in 1982, and consequently this serovar appears in the REvised List (1988) in the new serogroup Mini.
