### History of serovar:

The strain was isolated 1933 from a patient in Australia by Cotter and Sawers (1934) and studied by Lumley (1937), who tentatively named the group represented by this train Australis B.

Walch-Sorgdrager et al. (1938) studied the strain in more detail and found it to be closely related to Salinem.

In Wolff and room's list of 1954 the strain is placed already within the Pyrogenes group under the serovar name australis B, reference strain Zanoni/C 14.

The serovar name was changed later tozanoni-australis B (WHO, 1959),but in the 1965 list (WHO, 1965) only the name zanoni is given as both teh serovar name and strain name. The strain was submitted to factor analyisis by Kmety (1967), on the basis of which it was suggested that the serovar should be placed in subgroup Zanoni (Dikken, Kmety, 1978).
