Tsetse fly induced humoral responses in mice.

Long-term follow-up of (A) the anti-G. m. morsitans saliva IgG responses and (B) the anti-rTsal1 IgG responses in mice (n = 8/group) exposed to 4 different tsetse fly biting intensities (1 versus 10 flies) and frequencies (single versus weekly exposure for 3 weeks). Arrows indicate the tsetse exposure regimen for single exposed (red arrows) and multiple exposed mice (red and black arrows). Presented data are the mean ΔO.D.450 nm values and the 95% CI obtained with a 1∶1600 dilution of the individual plasmas.
