Ballum Mus 127 1944
Borg-Petersen (1944) isolated the strain Mus 127 from the urine of a field-house mouse (Mus musculus spicilegus), and described it as a new serovar ballum. It appears in the serovar list of 1959 (WHO, 1959). The strain was submitted to factor analysis by Kmety (1967), who confirmed its separate serological status.
