Abstract

Trypanosomiais prevalence was evaluated in the flocks of the cotton basin in the Sudanese zone of Côte d'Ivoire. The blood samples were taken from April 22 to May 21, 2016, on 582 cattle including 374 males and 195 females, belonging to the phenotypes Méré, Zébu and Ndama. Trypanosome species were first identified in the field from blood smears and then characterized in the laboratory using PCR (Polymerase Chain Reaction). The three species diagnosed are, in decreasing order of their prevalence rate, Trypanosoma congolense savannah group, Trypanosoma vivax and Trypanosoma brucei brucei. Most of the infected cattle come from Korhogo, followed by M'Bengué and then Ferkessédougou. The infection rate is lower and of the same order in Katiola, Koumbala, Diawara and Niellé. Méré are the most infected compared to Zebu and Ndama. The latter are the most weakly infected. For the Ndama, trypanotolerance appears to be even more efficient in animals less than 8 years old. The Méré show a strong parasitaemia due to Trypanosoma congolense or Trypanosoma vivax, without however being sick.
