云南省澄江市一起犬传人间布鲁菌病的流行病学调查处置

Epidemiological investigation and treatment of a human brucellosis case transmitted by dogs in Chengjiang City,Yunnan Province

通过对2023年澄江市一起人间布鲁菌病疫情现场调查分析,探讨分析引起人间布鲁菌病病因,为今后监测防控提供参考依据。通过对病例开展现场流行病学调查,进行疫区病例主动搜索,采集疫区内高危人员,羊、犬动物标本开展布鲁菌病检测和病原体分离培养,采用描述流行病学方法进行资料统计分析。该起疫情累计发现人间布病1例,从患者血标本分离培养出光滑型布鲁菌(羊种3型),从患者饲养的犬只检出光滑型布鲁菌抗体阳性2份,阳性率为16.67%,高危人员、山羊布鲁菌检测均为阴性,综合判定为一起通过犬向人间传播羊种布鲁菌疫情。该起疫情为人、犬共同感染光滑型布鲁菌(羊种3型),传播方式为少见的由犬到人模式,建议在今后疫情监测防控中重视犬布鲁菌病的预防控制工作,提高犬只养殖户防病意识。

To investigate and analyze the causes of a human brucellosis epidemic in Chengjiang City in 2023 through field epidemiological investigation,and to provide a reference for future surveillance and control.A field epidemiological investigation of the case was carried out,with an active search of cases in epidemic areas.Samples from high-risk individuals,sheep,and dogs in the epidemic area were collected for brucellosis testing and pathogen isolation and culture,and the data were statistically analyzed by descriptive epidemiological method.One case of human brucellosis was detected in the outbreak,with smooth Brucella glabrata(ovine biotype 3)isolated from the patient's blood.Smooth Brucella glabrata antibodies were detected in two samples from the patient's dogs,with a positive rate of 16.67%.Tests for brucellosis in high-risk individuals and goats were negative,leading to a determination that this was an outbreak of ovine brucellosis transmitted from dogs to humans.This outbreak represented a rare instance of Brucella glabrata(ovine biotype 3)co-infected by humans and dogs.In dealing with the epidemic of human brucellosis,it is necessary to expand ideas and methods,strengthen the prevention and control of canine brucellosis,pay attention to the infection of dogs,and raise the protection awareness of dog farmers.
