Leptospira fort-bragg isolated from a rat in Barbados

Leptospira fort-bragg was isolated from the kidney tissue of a rat (Rattus rattus) trapped on a plantation in St. Philip Parish, Barbados. This constitutes the first reported isolation of this Autumnalis group serotype outside of the United States and its first known isolation from an animal species. Serologic evidence is presented which indicates that this serotype may be the cause of leptospiral infections in Barbadian cattle.
