Abstract

Leptospirosis is an emerging zoonosis of global concern; however, its contemporary occurrence in Sweden, a European country partly located north of the Arctic Circle, is poorly known. Four out of 30 brown rats, captured within urban districts in Sweden, were found to be positive for antibodies to Leptospira interrogans serovar Icterohaemorrhagiae. This serovar causes Weil's disease in humans, a severe infection with jaundice, renal failure, and hemorrhage. Our study is the first finding of this highly pathogenic serovar in Swedish rats since the 1930s.
