Epidemiological and clinical aspects of Brucella suis infection in 17 workers from a pork processing plant in Argentina occurring between January 2014 and July 2015 are presented. All patients reported working 9 h daily without adequate personal protection garment. Blood cultures were positive for Brucella spp. in 14 of the 17 patients (82.3%). All isolates were identified as B. suis biovar 1. Although fever, sweats, asthenia, myalgia and hepatic involvement were the most frequent clinical manifestations, an unusually high incidence of respiratory involvement was found. From 13 patients in which chest radiography was performed, four (30%) had radiological abnormalities, including lobar pneumonia in two cases (one with pleural effusion) and interstitial involvement in other two. The high frequency of respiratory involvement in our series makes necessary to consider brucellosis in the differential diagnosis of respiratory diseases in pork processing plant employees.
本文介绍了2014年1月至2015年7月间，阿根廷一家猪肉加工厂的17名工人感染猪布鲁氏菌的流行病学和临床情况。所有患者均报告称每天工作9小时，且未配备足够的个人防护装备。17名患者中有14名（82.3%）的血培养布鲁氏菌属呈阳性。所有分离株均鉴定为猪布鲁氏菌生物变种1。尽管发热、盗汗、乏力、肌痛和肝脏受累是最常见的临床表现，但发现呼吸道受累的发生率异常高。在进行胸部X线检查的13名患者中，有4名（30%）有影像学异常，包括2例大叶性肺炎（1例伴有胸腔积液）和另外2例间质性病变。我们系列中呼吸道受累的高频率使得在猪肉加工厂员工呼吸道疾病的鉴别诊断中必须考虑布鲁氏菌病。
