With the increasing use of real-time PCR techniques, Leptospira isolation has mostly been abandoned for the diagnosis of human leptospirosis. However, there is a great value of collecting Leptospira isolates to better understand the epidemiology of this complex zoonosis and to provide the researchers with different isolates. In this study, we have successfully isolated different Leptospira strains from BacT/Alert aerobic blood culture bottles and suggest that this privileged biological material offers an opportunity to isolate leptospires.
