### History of serovar:

During on outbreak of seven-day fever occurring in a dairy-farming community near Pomona in North Queensland (Australia), Clayton et al.(1937), isolated this train in 1936 from the blood of a patient.

They found the strain antigenically distinct from other serovars known to them. Lumley (1937) and Johnson & Brown (1938) also compared the strain with other strins and confirmed the previous findings. Later Derrick (1942), after having studied 80 cases concluded that the strain Pomona represented a new serovar which he named pomona. The serovar is already quoted in the list of Wolf & Broom of 1954.
