Abstract

Serological data on leptospira infection were reported and discussed. From 1995 to 2001, the blood serum samples of 9885 domestic and wild animals and humans, living in Northern and Central Italy, were examined by the macroagglutination test (MAT) employing bratislava, ballum, canicola, grippotyphosa, icterohaemorrhagiae, pomona, hardjo and tarassovi serovars as antigens. Considering sera with > or = 1:400 antibody titers as positive, 674 (6.81%) animals scored positive. Sheep, horses, pigs and dogs gave the highest number of positive responses, particularly against the serovar bratislava and, for dogs, against icterohaemorrhagiae. The percentages of seropositivity observed in the most important animal species were: 12.13% in ovine (132 positive among 1088 tested animals), 11.40% in horses (107 positive animals among 938), 9.46% in swine (123 positive animals among 1299), 6.36% in dogs (278 positive animals among 4369), 2.39% in wild boars (11 positive animals among 459), 1.39% in deer (2 positive animals among 143), 0.48% in cattle (3 positive animals among 626). Among 250 human sera examined, 14 (5.60%) scored positive.

摘要

报告并讨论了有关钩端螺旋体感染的血清学数据。1995年至2001年期间，采用布拉迪斯拉发、巴伦、犬型、流感伤寒型、出血黄疸型、波摩那型、哈焦型和塔拉索夫型血清型作为抗原，通过宏观凝集试验（MAT）对生活在意大利北部和中部的9885只家畜、野生动物和人类的血清样本进行了检测。将抗体效价≥1:400的血清视为阳性，674只（6.81%）动物检测为阳性。绵羊、马、猪和狗的阳性反应数量最多，特别是针对布拉迪斯拉发血清型，而狗则是针对出血黄疸型。在最重要的动物物种中观察到的血清阳性率分别为：绵羊12.13%（1088只检测动物中有132只阳性），马11.40%（938只中有107只阳性动物），猪9.46%（1299只中有123只阳性动物），狗6.36%（4369只中有278只阳性动物），野猪2.39%（459只中有11只阳性动物），鹿1.39%（143只中有2只阳性动物），牛0.48%（626只中有3只阳性动物）。在检测的250份人类血清中，14份（5.60%）呈阳性。
