### History of serovar:

The strain was isolated in 1952 from a patient in North Queensland, Australia, by Smith et al. (1954). Badudieri (1956) studied the strain and described it as an incomplete biotype of mini.

Wolf and Bohlander (1958) checked the serological status of the strain and considered it to be a new serovar which they named szwajizak.

In the serovar list of 1959 (WHo, 1959) the strain is listed as a subserovar of mini, within the Hebdomadis group, but in the list of 1967 (WHO, 1967) serovar szwajizak is reported as a separate serovar.

The strain was submitted to factor analysis by Kmety (1977), who confirmed its separate serological status and proposed placing it in the new Mini serogroup. During the TSC Boston meeting of 1982) this proposal was accepted.
