  The study involved the evaluation of the effect of T. congolense infection on pyruvate concentration in the serum of Yankassa sheep. Three groups of six sheep each were used; groups A and B were experimentally infected with T. congolense. Animals in group A were treated with Diminazene aceturate after first peak of parasitaemia but group B animals were left untreated. Sera of infected and uninfected control sheep were analyzed using DNS method to determine pyruvate and its concentrations. Group B animals which were not treated had mean values which were lower compared to that of group A (post treatment) and the control. Mean values of 72.4-25.7 g L-1, 79.6-5.2 g L-1 for groups A and B respectively were significantly different (p<0.0001) and indicative that the presence of parasites might have enhanced depletion of the pyruvate in the plasma. However, the cause of pyruvate depletion which occurred when the trypanosome parasites were in general circulation needs further investigations.

  The concentration change of pyruvate was studied in serum of uninfected and infected sheep with T. congolense. In the uninfected, the mean concentration of 61.23-76.63 mg L-1 of pyruvate was determined using the DNS method. There was a depressed concentration of pyruvate in the two infected groups (A and B); pyruvate level fell to 25.7 mg L-1 in gp A that was treated immediately after the first peak of parasitaemia while in gp B, the concentrations continued to fall (5.2 mg L-1) until the termination of the experiment. The fall might have been as a result of the utilization of the pyruvate by either the host or its conversion to other compounds. It is therefore concluded that animals use the pyruvate or its converted to another compound during trypanosome infection. The decrease in pyruvate levels may be a possible cause of weakness and eventual death in infected animals.

  Mitracarpus scaber is a local herb traditionally used for the treatment of eczema and other skin disorders. Methanolic extracts made from leaves, stem, fluorescence and roots were prepared and dried. Graded concentrations of the 4 separate plant parts were prepared in nutrient broth contained in universal bottles at 10, 7, 5, 3 and 2 g mL 1. Standard chloramphenicol (Norbrook Laboratories Ltd., London) was similarly prepared and used as known antibiotic. An isolate of Dermatophilus congolensis was obtained and inoculated in each of the graded broth media and incubated at 37C, microaerophilically, for 24 h. Two replications were made with blank controls and growth of Dermatophilus congolensis was observed and recorded. The results obtained showed that leaves, fluorescence and root extracts were inhibitory at concentration of 3 g mL 1 while, stem extract was at 5 g mL 1. Chloramphenicol was inhibitory at 2 g mL 1. It is recommended that research be carried out on this plant to further elucidate its antimicrobial potentials.
