Imported Leptospira licerasiae infection in traveler returning to Japan from Brazil

Abstract

We describe a case of intermediate leptospirosis resulting from Leptospira licerasiae infection in a traveler returning to Japan from Brazil. Intermediate leptospirosis should be included in the differential diagnosis for travelers with fever returning from South America. This case highlights the need for strategies that detect pathogenic and intermediate Leptospira species.
