Methods In 2007, the basic situation of people of 7-60 years old and in close contact with livestock was surveyed in Dalian according to the "Surveillance standard for brucellosis"(GB 16885-1997). Blood was collected in brucellosis suspicious or high-risk groups for the laboratory examination, using rose bengal test for qualitative detection and test-tube agglutination test(SAT) method for quantitative detection of serum antibodies; At the same time, brucellosis cases found in the routine monitoring and confirmed in and this survey in the department of endemic disease prevention in the center for disease control and prevention of Dalian City underwent questionnaire surveys. Results All 1563 people were epidemiologically surveyed of brucellosis, 1310 were male, 253 female,livestock care givers accounted for 56.05% (876/1563). 240 blood samples were serologically surveyed, the detection rate was 3.75%(9/240). This survey confirmed 2 cases of brucellosis patients, 3 cases confirmed in routine monitoring. 3 cases were infected via contacting infected brucellosis cows, and the 2 cases were imported. Conclusions To strengthen the quarantine of livestock and timely treat the infected livestock should be the key of control of brucellosis. At the same time, professionals of livestock should be educated to protect themselves.
