Prevalence of bovine trypanosomiasis in the kangaba circle (Mali)

This study carried out between September and November 2023, in the Kangaba circle aimed to determine the prevalence of trypanosomiasis. Blood samples taken from 219 cattle comprising 142 females and 77 males examined for trypanosomes. Trypanosomes identified using the Buffy coat technique. This work made it possible to obtain a prevalence of 35.16% bovine trypanosoma. Statistical analysis revealed a statistically significant difference (p<0.05) between the prevalence rates observed in the different species of trypanosomes identified, such as Trypanosoma .congolense (68.83%), T. vivax (19.48%). %) and T. brucei (11.69%). The prevalence of trypanosomiasis observed in male and female cattle was 42.86% for male cattle and 30.99% for females. Statistical analysis of the results revealed a significant difference (p<0.05) between trypanosomiasis prevalence rates observed in adult cattle (8.14%) and in young cattle (52.63%). In the commune of Kaniogo, out of 110 cattle examined, 42 individuals were positive for trypanosomiasis, representing an overall prevalence rate of 38.18%. Regarding the commune of Karan, 35 cattle were positive for trypanosomiasis out of 109 subjects examined, representing an overall prevalence rate of 32.11%. The results of our work revealed that bovine trypanosomosis constitutes a real threat to cattle in the Kangaba circle.
