摘要目的：分析布鲁菌病临床流行病学的变化特点，以利于布鲁菌病的积极预防控制。方法对105例布鲁菌病临床流行病学资料进行回溯性调查。结果105例布鲁菌病患者中，农民94例（89．52％），城镇居民31例（10．48％），男性占70．48％，主要发病年龄51～60岁（33．33％）；发病时间分布显示以夏末秋初发病最甚；有明确牛、羊接触史的89例患者中，在与牛、羊接触工作时采取防护措施的仅15例（16．85％）；该组资料中，总共涉及山西省8个地区，分布集中在太原市附近；该组患者有直接或间接有牛、羊接触史者93例，达88．57％，流行病学史非常明确，但仅22．86％患者首诊确诊为布鲁菌病。结论布鲁菌病流行模式发生了很大变化，报告病例的地区数逐年增加，城区居民发病比例上升，疫区从牧区向农业区、城市蔓延，流行形式以多发、分散的点状流行代替了大规模的暴发流行形式，发病者的人群从传统的职业人群向非职业人群扩散。
