Leptospirosis survey in wild rodents living in urban areas of Rome.
The aim of the study was to survey the current extension of the infected brown rats (Rattus norvegicus) living on the site Ripa Grande-San Michele port located in the center of the sity along the accessible right bank of the Tiber river by using a specific molecular technology. The detection of Leptospira, in 11 trapped brown rats, by tube-based Polymerase Chain Reaction (PCR) was performed. The amplified samples were analysed by capillary zone electrophoresis (CZE). Sequence analysis of the amplified DNAs confirmed the specificity of the detection of leptospires. Five out of 11 brown rats exhibited positivity for Leptospira. The survey points out the high rate of leptospiral infection in the brown rats living in the most ancient urban area of Rome.
