An epidemiological investigation of one case of human streptococcus suis type 1 infection in Jiangxi Province

目的通过对江西省一例人感染1型猪链球菌病例的流行病学调查与分析,查找可能的感染来源,为人感染1型猪链球菌病病例的防治提供科学依据。方法采用描述流行病学方法分析。结果经流行病学调查发现,该病例在发病前1周食用过市场上购买的猪肉,可能通过接触携带1型猪链球菌的猪肉感染。结论 1型猪链球菌一般不导致人类感染,但对免疫功能低下或伴有基础性疾病的老年人有致病性,要进一步关注1型猪链球菌毒力的变化和耐药情况,以便今后更好地应对此类病例,减少死亡。
