| 目的 分析海南省布鲁氏菌病（布病）流行病学特征。方法 对2012-2017年海南省收集的16株布鲁氏菌采用Vitek 2 compact进行布鲁氏菌初步鉴定，再用传统生物学分型方法进行确证，结合饲养家畜血清学和病原学检测结果分析患者的流行病学特征。结果 Vitek 2 compact鉴定12株为羊种布鲁氏菌，4株为人苍白杆菌。传统生物学分型方法鉴定11株为羊种布鲁氏菌3型，5株为猪种布鲁氏菌3型。菌株对应的16例病例中2012年1例，2013年2例，2014年4例，2015年1例，2016年2例，2017年6例，分布在东方市、临高县、海口市、万宁市、乐东县、定安县等地。同时对疫区东方市745份羊血清进行布鲁氏菌血清抗体检测，阳性47例（6.3%），从东方市病羊采集的标本中分离到羊种布鲁氏菌3型。结论 Vitek 2 compact是一种简单、方便的布鲁氏菌鉴定方法，但不能替代传统生物学分型方法；海南地区布病主要流行的菌种为羊种3型及猪种3型，通过东方市2017年布病疫情，说明海南省有布病疫畜传染人的疫情，布病防控形势严峻。 |

| Objective To understand the epidemiological characteristics of brucellosis in Hainan province. Methods Automatic microbial identification system of Vitek 2 compact was used for the preliminary identification of 16 brucellosis cases in Hainan province from 2012 to 2017, and further confirmation was performed with traditional biological typing methods. The epidemiological and clinical characteristics of the patients were analyzed in combination with the results of serological and etiological tests for raised livestock. Results Vitek 2 compact detection results showed that 12 strains were Brucella (B.) melitensis and 4 strains were Ochrobactrum anthropi. Traditional biological typing methods showed that 11 strains were B. melitensis biovar 3 and 5 strains were B. suis biovar 3. Sixteen cases were found in Dongfang, Lingao, Haikou, Wanning, Ledong and Ding'an with 1 case in 2012, 2 cases in 2013, 4 cases in 2014, 1 case in 2015, 2 cases in 2016 and 6 cases in 2017 respectively. At the same time, 745 sheep serum samples from the epidemic area (Dongfang) were collected for Brucella serum antibody detection, in which 47 were positive (6.3%). And B. melitensis biovar 3 was isolated from samples collected from sick sheep in Dongfang. Conclusions Vitek 2 compact is an simple and convenient method for Brucella identification, but it cannot replace traditional biological typing methods yet. The major epidemic strains of Brucella in Hainan were B. melitensis biovar 3 and B. suis biovar 3. The epidemic of brucellosis in Dongfang in 2017 indicated that brucellosis had spread from animal to human in Hainan, and it is very important to strengthen the prevention and control of brucellosis in Hainan. |
