ABSTRACT
Objective The main purpose is to investigate the status of brucellosis infection in high-risk areas of Urumqi and population characteristics,and to provide a basis for prevention of brucellosis.Methods In Urumqi City,Dabancheng District,Gaoxin District,Midong,Zone and Urumqi County were selected as survey sites;according to pastoral,agro-pastoral and agricultural,all towns in each survey site were classified into three categories;150 to 200 residents in each township were selected as subjects.Basic demographic information was collected,and blood samples were collected for serological detection.rose bengal plate agglutination test (RBPT) was used for preliminary screening,RBPT positive persons were further confirmed by standard tube agglutination test (SAT).Different regions,gender,age,occupation,exposure difference and brucellosis infection rates were studied.x2 test was used to compare rates.Results The infection rate was 5.42％ (29/535).Furthermore,the infection rate ofthe Dabancheng District [10.34％ (12/116)] was higher than those of Gaoxin District [2.94％ (3/102)] and Urumqi County [2.58％ (4/155),x2 =4.643,7.199,all P ＜ 0.05],the differences were statistically significant (x2 =9.327,P ＜0.05).Besides,infection rate of the average exposure occupation [8.33％ (24/288)] was higher than those of low exposure occupation [0(0/61)] and high exposure occupation [2.72％ (5/184),x2 =5.459,6.140,all P ＜ 0.05].The differences were statistically significant (x2 =10.846,P ＜ 0.05).The differences of infection rates in ages and nations showed no statistical significance (x2 =2.396,4.639,all P ＞ 0.05).Conclusions High risk areas of brucellosis are still exist in Urumqi.Health education should be strengthened in the future,in order to enhance residents' seff-protection awareness in exposed population.
