Abstract：Cross-section study was conducted to estimate the seroprevalence of brucellosis, identify risk factors for animals testing seropositive, and assess the knowledge, attitude and practices (KAPs) of livestock owners regarding to brucellosis. A total of 69 630 goat serum samples were detected using rose bengal test (RBT) and standard tube agglutination test (SAT), which collected from different large-scale farms in Dazhou during 2015 and 2018, and a field questionnaire survey and analysis was conducted to investigate the basic information of farm, breeding, biosecurity. The results showed that a total of 835 positive sera were detected in 59 positive farms, and the samples positive rate, farm positive rate for brucellosis were respectively 1.20% (835/69 630) and 1.84% (59/3 199) in during 2015 and 2018. The farm annual positive rate for brucellosis were respectively 6.31% (28/444), 2.34% (18/769), 0.85% (12/1 417) and 0.18% (1/569) (n=3 199, χ2=66.415,P<0.05), and sample annual positive rate were 4.55% (376/8 268), 1.90% (263/13 810), 0.61% (195/32 001), and 0.01% (1/15 551) (n=69 630, χ2=1 121.088,P<0.01) in recent four years. In addition to Qu County, the positive samples for brucellosis were detected in the different scale farms of the other six counties, mainly in the form of a point-like sporadic epidemic. The positive rate of farm with goat number less than 50 was higher, however the significant difference was not found(n=3 199, χ2=0.497,P>0.05). Comparing with other districts, the positive rate of Dachuan District is significantly different (n=3 199, χ2=34.612,P<0.05). The questionnaire survey found that three factors including goat introduction (OR=9.11, 95%CI:1.08~77.29) were the main risk factors in the past one year. The brucellosis cases of Dazhou City showed a downward trend in recent years, and goat introduction, farmer’s poor awareness of biosecurity and brucellosis were the main risk factors for brucella infection of goat in this region.
