First report of human infection with Leptospira interrogans serovar Bratislava in the Eastern Black Sea region of Turkey

Leptospirosis is one of the most common zoonotic bacterial infections worldwide. It is an infection that usually affects people with low socioeconomic status, with morbidity and mortality risk. The clinical course of the disease may range from mild, featuring nonspecific clinical signs and symptoms, to severe, resulting in death. The respective studies conducted in Turkey indicate that leptospirosis seropositivity in animals and humans is higher in coastal and rural areas. Turkey’s Eastern Black Sea Region has a humid climate with heavy rainfalls and a large population of mice and other rodents. However, a Leptospira interrogans serovar Bratislava case is yet to be reported in this region. This article reports the case of a 38-year-old patient who presented fever and acute renal failure and was diagnosed with Leptospira interrogans serovar Bratislava after hospitalization.
