[Analyse on the epidemiological characteristics of brucellosis and in Inner Mongolia through the observation of the change among Brucella species].

This article analysed the epidemiological characteristics of Brucellosis in Inner Mongolia. Data had been collected for the last fourty years since 1,937 on the changes of Brucella species in their distribution, variation, toxicity, types, etc. The authors pointed out that changes of Brucella species played a decisive role in changing the epidemiological patterns, while intentionally active or passive intervention importantly contributed to the change of Brucella species. It was emphasized that the survey on Brucella species and the dynamic change of epidemiological features were closely related which should not be ignored for the forecasting of Brucellosis epidemics.
