There was no significant difference in growth of WT parasite in the presence or absence of GlcN (the parasitemia at day 4 were 7.01±0.41, 0.27±0.11, 6.25±0.36, 0.16±0.07, 7.03±0.19, and 6.27±0.12 for Tg1 GlcN-, Tg1 GlcN+, Tg2 GlcN-, Tg2 GlcN-, WT GlcN-, and WT GlcN+, respectively, average ± SE; Fig 2E). This evidence concerns the gene TGM2 and parasitic infectious disease.
