### History of serovar:

The strain was isolated in 1964 by Nitynanda from a bakerr living near Colombo, Shri-Lanka (Ceylon), and was included in Annex 2 of the list of 1967 (WHO, 1967) although not yet published. Inthis list the strain name is given as Dynanda of serovar ceylonica. Nityananda and Sulzer described the strain in 1969 and desginated it Piyasena, which takes precedence over Dyananda.
