Figure 7From: What have we learned from brucellosis in the mouse model?Spleen cell proliferation (3 H-thymidine incorporation) in response to killed B. abortus 2308 in BALB/c mice infected with B. abortus virulent 2308 or vaccine-attenuated S19 strains, during 20 weeks [adapted from [[152]] with permission]. Notice the delay in response of spleen cells from 2308 infected mice in relation to those infected with the attenuated strain S19.Back to article page
