目的了解南宁市职业人群布鲁菌感染状况,为开展科学防治工作提供依据。方法采用试管凝集试验对南宁市南、北2大奶场的饲养员、挤奶工和农贸市场的生畜肉的销售员进行3年的布鲁菌抗体血清学跟踪检测。结果 636人份血清中检出阳性37份,阳性率为5.81%,南边奶场和农贸市场畜肉类销售员均为阴性。阳性感染者集中在北边奶场,且数量呈逐年递增趋势。检测和回访中发现阳性感染者血清抗体滴度以1:100～200者占97.30%(36/37),达到1:400仅1份,感染者未见有临床症状或有不适。结论本市职业人群布鲁菌感染者的抗体阳性滴度不高,几乎均无临床症状。控制家畜布鲁菌病的流行是降低人群布鲁菌感染率的关键,同时应继续关注并跟踪隐性感染者的健康状况。
Objective To understand the prevalence of brucellosis among occupational groups in Nanning and provide the basis for scientific prevention and treatment. Methods Tubes agglutination test was carried out to detect the brucellosis serology of brucellosis serogroups in breeders, milking workers and farmer’s markets of south and north two big dairy farms in Nanning City. Results A total of 37 positive samples were detected in 636 serum samples, the positive rate was 5.81%. The meat salesmen in the south dairy farms and farmers’ markets were all negative. Positive infections were concentrated in the north dairy farm, and the number showed a trend of increasing year by year. Serum antibody titers of positive patients infected with positive infection were 97.30% (36/37) in 1: 100 ~ 200 cases and reached 1: 400 in 1 case. There was no clinical symptoms or discomfort in those infected. Conclusion The antibody positive titers of brucellosis in occupational population of this city are not high, almost no clinical symptoms. Controlling the prevalence of brucellosis in livestock is key to reducing the prevalence of brucellosis in the population and should continue to focus on and track the health status of those with latent infection.
