### History of serovar:

The strain was isolated from the urine of a spiny rat (Proechimys semispinosus) in the Panama Canal Zone by Gale (1966) and typed by Galton (WHO, 1967).

It was included in the serovar list of 1967 as a recognized new serovar balboa, reference strain LT 761, although no description had been published at that time.

The isolation and the descirption of the strain was not published until 1982 (Sulzer et al., 1982). In that publication the strain name is designated 73 U, which therefore takes precedence over the laboratory code LT 761.
