Table 5: 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 | 0 | - |
| Reference drug | 6 | 5 | 8 ± 10.95 |
| Anti-Tryps serum (μl/g bw) | |||
| 2.5 | 6 | 2 | 40 ± 0*a |
| 5 | 6 | 3 | 33 ± 11.55*a |
| F = 9.43 ; P = 0.01 | |||
Asterisks show the significant difference (P < 0.05) between the groups of mice that received the anti-tryps serum and the reference drug. Letters show the significant difference (P < 0.05) between the groups of mice that received the anti-tryps serum.
