Plasma nitric oxide levels (μM) of chickens infected with Plasmodium gallinaceum, treated (black bars) or not (gray bars), with aminoguanidine and grouped by parasitemia ranges (PR). For noninfected chickens: n = 15 for untreated and n = 13 for treated; for PR of <1: n = 6 for untreated and n = 4 for treated; for PR of 1–10: n = 6 for untreated and n = 9 for treated; for PR of 11–20: n = 4 for untreated and treated; for PR of 21–30: n = 4 for untreated and treated; for chronic chickens: n = 18 for untreated and n = 10 for treated. ## Statistically significant (p < 0.01) in relation to the noninfected value. *Statistically significant (p < 0.05) in relation to the respective treated value. Data are from one representative experiment.
