title: Human leptospirosis in Italy, 1986-1993.
abstract: In the eight-year period 1986-1993, the Italian National Center for Leptospirosis and the Regional Leptospira Laboratories confirmed 312 cases of clinical leptospirosis by using the microscopic agglutination (MA) assay. The majority of cases was observed in Northern regions of the Country. Cases were reported in all age groups, but were most common in the working-age population. Of 312 cases, 291 (93.3%) occurred among males. The largest number of infections was ascribed to occupational activities (45.8%). The typical leptospiral seasonal course, with a peak during the summer, was observed. Involvement of the liver was the most frequent manifestation. Influenza-like symptoms were the only signs of illness in 11.1% of cases. Anti-leptospira antibodies, cross-reacting with two or more serovars, were found in 28.2% of sera. The most frequent serovar-specific antibodies were those against poi, icterohaemorrhagiae, bratislava, copenhageni and sejroe.
