Figure 7From: Dynamics of infection and competition between two strains of Trypanosoma brucei bruceiin the tsetse fly observed using fluorescent markersComparison of paired salivary glands from a single fly. Paired salivary glands from individual flies dissected at (A) 2 weeks, and (B) 4 weeks post infected feed. Gland 1 of each pair has a mixed infection and gland 2 a single infection. At the early stage of establishment (A), both glands have about the same density of trypanosomes, while at the later stage (B), trypanosomes in the gland with the mixed infection appear to be more dense than in the gland with the single infection.Back to article page
