Parasitemia of T. congolense isolates during the experimental infection in mice.

Table 7: Parasitemia of T. congolense isolates during the experimental infection in mice.

Treatment	Number of mice tested	Number of animal resistant	Average parasitemia (Parasites/ml blood)
Normal serum	6	5	33 ± 11.55^ns
Reference drug	6	5	35 ± 19.15^ns
Anti-Tryps serum (μl/g bw)
2.5	6	4	8 ± 17.89^ns, ^a
5	5	3	4 ± 8.94^*,a
	F = 4.39; P = 0.02

Asterisks show the significant difference (P < 0.05) between the groups of mice that received the anti-tryps serum and the control group (Normal serum). Letters show the significant difference (P < 0.05) between the groups of mice that received the anti-tryps polyclonal serum.
