[Anti-rabies measures by the Infectious Disease Prevention Service at the "La Sapienza" University of Rome in the years 2005-2007].

Antirabies service activities of the Infectious Diseases Prophylaxis Centre of the Sapienza University of Rome during the period 2005-2007. Authors analyzed data, of antirabies activity, from 3206 patients treated at the Infectious Diseases Prophylaxis Centre of the University of Rome "La Sapienza" during the period 2005-2007 Dogs were responsible for most bites (92.1%).

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).

Persistent hepatitis G virus (HGV) infection in chronic hemodialysis patients and non-B, non-C chronic hepatitis.

Three groups of patients have been studied longitudinally for 24 months to analyze the role of hepatitis G virus (HGV) in hepatic disease. Group 1 consisted of 50 patients with non-B, non-C chronic hepatitis, group 2 consisted of 44 hemodialyzed patients, and group 3 consisted of 50 healthy blood donors. The presence of HGV RNA was detected by both reverse transcription-polymerase chain reaction (RT-PCR) and capillary zone electrophoresis (CZE).

Detection and clinical evaluation of GBV-C/HGV in plasma from patients with chronic hepatitis of unknown etiology.

Purpose: The role of GBV-C/HGV virus infection in patients with chronic hepatitis of unknown etiology has been studied. Two groups of patients have been included: a) 50 consecutive patients with chronic hepatitis (mean age 47 yrs; M/F = 35/15), negative for markers of hepatitis viruses (HBV-HCV). These patients did not show evidence of metabolic, autoimmune, alcoholic or toxic liver disease; b) 50 healthy blood donors (mean age 35 yrs; M/F = 35/15).
