Abstract:
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.
