In 1987 a seroepidemiological research was performed to verify the prevalence of leptospira agglutinins on the urban and rural population of Milan, Bergamo and Mantova Provinces in Lombardia Region. Were controlled 150 subjects (75 males and 15 females) in Milan town, 58 (49 males and 9 females) in municipalities of Bergamo Province, and 68 (55 males and 13 females) of Mantova Province. La prevalence of leptospira agglutinins in exposed subjects was 14.3% and in unexposed subjects 8.6%. In the females was noted a significative higher prevalence of agglutinins (14.4%) than in males (9.5%), especially in the females exposed (36.3%) than in females unexposed (9.6%). The leptospira serovars most interested were L. sejroe (15.9%), L. poi (13.6%), L. bratislava, L. canicola and L. Zanoni (9.1%). The sera tested proved reactivity of 56.8% also against two or three different serovars of pathogenic leptospira and prevalence of 13.6% of coagglutinins against nonpathogenic L. patoc serovar.
1987年进行了一项血清流行病学研究，以核实伦巴第大区米兰、贝加莫和曼托瓦省城乡人口中钩端螺旋体凝集素的流行情况。在米兰市对150名受试者（75名男性和75名女性）进行了检测，在贝加莫省各市对58名（49名男性和9名女性）进行了检测，在曼托瓦省对68名（55名男性和13名女性）进行了检测。暴露组中钩端螺旋体凝集素的流行率为14.3%，未暴露组为8.6%。女性凝集素的流行率（14.4%）明显高于男性（9.5%），尤其是暴露女性（36.3%）高于未暴露女性（9.6%）。最常涉及的钩端螺旋体血清型为 sejroe 型（15.9%）、poi 型（13.6%）、布拉迪斯拉发型、犬型和扎诺尼型（9.1%）。检测的血清对两种或三种不同致病性钩端螺旋体血清型也有56.8%的反应性，对非致病性巴托斯血清型的协同凝集素流行率为13.6%。
