Haemoassessment of Dogs Experimentally Infected with Single and Conjunct Trypanosoma congolense and Ancylostoma caninum and Treatment with Diminazene Aceturate and Mebendazole

Abstract

The haemoassessment of dogs with single Trypanosoma congolense (T. congolense) and conjunct T. congolense /A. caninum was determined in this study. Twelve mongrels of both sexes weighing between 4 to 8 kg were grouped into 3 of 4 members each. The group i (GPI) was the uninfected (control), group ii (GPII) was infected with T. congolense and group iii (GPIII) was conjunct infection of T. congolense/A. caninum. Post acclimatization GPIII was infected with 200 infective L3 of A. caninum, 2 weeks later both GPII and GPIII were given 2.5x106 trypanosomes intraperitoneally. Three weeks post trypanosome infection, treatment was done with 100 mg of mebendazole twice daily for 3 days and 7 mg/kg of diminazene aceturate. Result showed a significant decrease (p<0.05) in PCV, Hb and Rbc of both GPII and GPIII. The decrease in GPIII was more compared to that in GPII. There was significant decrease (p<0.05) in neutrophil, monocyte, lymphocyte and eosinophil counts of both GPII and GPIII except in basophil count which showed no significant difference (p<0.05) from GPI (control) throughout the experiment. Treatment with both diminazene aceturate and mebendazole cause significant haematological improvement.
