Table 2.
The prevalence of T. evansi, T. vivax and mixed infection in camels with different diagnostic tests
| Area | Giemsa-stained blood smearsa | Wet blood filmb | MHCT | KIN-PCR T. evansi |
RoTat 1.2 VSG-PCRc | KIN-PCR T. vivax |
TviCatL-PCR | Mixed infectiond |
|---|---|---|---|---|---|---|---|---|
| East Nile | 9% (13/148) | 14% (20/148) | 22% (33/148) | 36% (54/148) | 59% (32/54) | 25% (37/148) | 33% (49/148) | 19% (28/148) |
| West Nile | 0% ( 0.0/41) | 3% (1/41) | 7% (3/41) | 39% (16/41) | 56%(9/16) | 24% (10/41) | 24% (10/41) | 15% (6/41) |
| Total | 7% (13/189) | 11% (21/189) | 19% (36/189) | 37% (70/189) | 59% (41/70) | 25% (47/189) | 31% (59/189) | 18% (34/189) |
aGiemsa-stained blood smears: 10 samples showed typical T. evansi morphology, 2 samples showed typical T. vivax morphology and 1 sample showed mixed infection
bWet blood film: 19 samples showed a typical T. evansi movement pattern while 2 samples showed a typical T. vivax movement pattern
cA RoTat 1.2 VSG-PCR was performed on KIN-PCR-positive samples (70 samples)
dMixed infection was defined by KIN-PCR-positivity for T. evansi and TviCatL-PCR-positivity for T. vivax
