Background: Trypanosomosis is an important disease of both humans and animals commonly found in most parts of Africa and South America. Because of their activities, the parasites produce numerous changes in the cellular and biochemical constituents of blood. Also, trypanosomosis cause immunosuppression and also induce lipid peroxidation in the host. Probiotics confer beneficial health benefit to the host such as immune stimulation, protection against pathogens, metabolism, reduced oxidative stress, etc.

Methods: Thirty (30) adult albino rats were assigned into 5 groups (A – E) of 6 rats each. Groups A, B and C rats were fed feed supplemented with probiotics at 0.08, 0.12 and 0.16 mg per kg respectively. On day 14 on the supplementation (OTS), groups A, B, C and D rats were infected with 1 x 106 trypanosomes intraperitonealy. Group E served as the not infected, not supplemented control.

Results: The pre-infection supplementation did not vary the serum alanine transaminase (ALT), aspartrate transaminase (AST), urea, creatinine and total protein values of groups A, B and C. However, following infection, the ALT value of group D (infected, not supplemented) was significantly (p<0.05) higher than other groups on day 42 OTS. Also, the AST value of groups A and D were significantly (p<0.05) higher than group E but not with groups B and C on days 42 and 56 on the supplementation. On day 28 OTS, the urea level of group B was significantly (p<0.05) lower than group D whereas on days 42 and 56, group E and groups E and C were significantly (p<0.05) lower than other groups respectively. The serum creatinine level showed increase following infection with groups A and D being significantly (p<0.05) higher than other groups on days 42 and 56 OTS. On day 28 OTS, the total protein value of group A was significantly (p<0.05) lower than group C but not with other groups. By days 42 and 56 OTS, group D showed significantly (p<0.05) lower protein level when compared with other groups. The mean parasitaemia level of group D was significantly higher than other infected infected groups on days 28 and 42 on the supplementation. However, on day 56, the parasitaemia level of all infected groups did not vary (p>0.05).

Conclusion: The ability of the supplementation to keep serum biochemical values before infection within range, and the subsequent maintenance of the value during most part of the infection were indication that probiotic was not toxic and may play a vital role in management of trypanosomosis.
