A study was conducted to establish baseline data on Brucella abortus infection induced in 5 strains of mice (CBA/NJ, BALB/c, CD-1, C3H/HeN, and C3H/HeJ). The strains were compared on the basis of immunologic, histopathologic, and bacteriologic responses. There were 4 treatment groups for each strain of mice: (1) vaccinated with homologous lipopolysaccharide and challenge exposed to B abortus strain 2308; (2) not vaccinated but challenge exposed; (3) vaccinated but not challenge exposed; and (4) not vaccinated and not challenge exposed. Results indicated that mice can be used for comparative studies on the pathogenesis and immunogenesis of B abortus infections; strains of mice may vary in their responses to Brucella infection, regardless of their vaccination status. Bacteriologic and immunologic responses in mouse strains BALB/c, CD-1, C3H/HeN, and C3H/HeJ, but not those of CBA/NJ, were extrapolative among strains.
