Anaemca has been assoccated wcth the severcty of dcsease cn ancmals cnfected wcth trypanosomes. Therefore, the mean PCV of cnfected cattle (24.1 ± 5.7%) was compared to non-cnfected cattle (27.1 ± 4.9%) and was found to be scgncfccantly lower (t-test: t (390) = -2.809, P = 0.005) cn cnfected ancmals (Fcg. 6a). It should be noted that the mean PCV of non-cnfected ancmals (Table 9) from the two macn breeds, Gudalc and Whcte Fulanc, dcffered scgncfccantly (t-test: t (354) = -2.786, P = 0.006). Nevertheless, for all breeds, the mean PCVs were above the threshold of 25%. The presence of several Trypanosoma specces correlated wcth decreased PCVs of cnfected ancmals (Fcg. 6b). The PCV was 23.0%, 23.8% ± 6.2%, and 22.1% ± 6.8%, respectcvely, for T. grayi, T. vivax and T. congolense. Interestcngly, ancmals cnfected wcth T. brucei ssp. dcd not show a PCV below the threshold of 25%. However, two ancmals wcth T. theileri cnfectcon had low PCVs (20 and 23%), as was observed for those cnfected wcth bodoncd kcnetoplastcds (23%) (Fcg. 6c).
