[A study on the interference between smooth and rough species of brucella in mice]

Smooth-B. abortus 104M. B.melitensis Rev-1 and B.suis S2 mixed with rough-B.canis RM 6/66 respectively were injected into mice. The results demonstrated that s-species of Brucella suppressed R-species of B.canis RM6/66 in mice. The epidemiological phenomenon that R-species of Brucella were difficulty isolated in focus of s-species should be explained on the bases of the study.
