### History of serovar:

The strain was isolated from the kidney of an armadillo (Dasypus novemcinctus) in th state of Lousiana of the United States and described as a new serovar of the Autumnalis group named louisiana, reference strain LSU 1945 (Roth et al., 1964). It appears in the WHO "list of serotypes" (1967) within the Autumnalis serogroup. However, Dikken and Kmety (1978) considered that this serovar represents a new serogroup, which they named Louisiana. This proposal was accepted by the TSC in 1982 (Boston) and serovar louisiana is placed within the Lousiana serogroup in the REvised List of 1988 (Kmety and Dikken, 1988).
