Pyk is crucial for the virulence of B. abortus in mouse model of infection. A Bacterial loads of the S2308 strain, the pyk mutant in the spleens of BALB/c mouse at 1 and 5 weeks post-infection. B Spleen weight of the S2308 strain and the pyk mutant infected mice at 1 and 5 weeks post-infection. C Bacterial loads of the S2308 strain, the pyk mutant and the complementation strain in the spleens of BALB/c mouse at 1 week post-infection. D Spleen weight of the S2308 strain, the pyk mutant and the complementation strain infected mice at 1 week post-infection *p ≤ 0.05; ***p ≤ 0.001.
