Table 2 The prevalence of T. evansi, T. vivax and mixed infection in camels with different diagnostic tests

From: Trypanosoma vivax is the second leading cause of camel trypanosomosis in Sudan after Trypanosoma evansi

  1. aGiemsa-stained blood smears: 10 samples showed typical T. evansi morphology, 2 samples showed typical T. vivax morphology and 1 sample showed mixed infection
  2. bWet blood film: 19 samples showed a typical T. evansi movement pattern while 2 samples showed a typical T. vivax movement pattern
  3. cA RoTat 1.2 VSG-PCR was performed on KIN-PCR-positive samples (70 samples)
  4. dMixed infection was defined by KIN-PCR-positivity for T. evansi and TviCatL-PCR-positivity for T. vivax
