This study was carried out to investigate the status of acid-base balance and blood gases in camels with trypanosomosis compared to healthy camels. The haematobiochemical profiles were also reported in both groups. Forty-two camels with chronic weight loss, ventral oedema and ascites were examined. Passive haemagglutination test showed that 38 of the 42 camels (90%) were positive for Trypanosoma evansi. Compared to a value of 7.54±0.16 in healthy camels, the blood pH in diseased camels was 7.37±0.051. The partial pressure of carbon dioxide (PCO2) was higher in camels with trypanosomosis than healthy camels. On the contrary, the oxygen partial pressure (PO2) was lower in camels with trypanosomosis. The base excess (BE) was also lower in diseased camels than healthy ones. Similarly the bicarbonate (HCO3) was lower in diseased camels. In a similar pattern, the total carbon dioxide (TCO2) was lower in diseased than healthy group. The oxygen saturation (SO2) decreased significantly in camels with trypanosomosis when compared to healthy group. Concerning the haematological parameters, leukocytosis, neutrophilia and lymphopenia was found in diseased camels. The RBCs count, haemoglobin and haematocrit decreased significantly in camels with trypanosomosis. Concerning, the biochemical parameters albumin and phosphorus decreased significantly and globulin and magnesium increased significantly in diseased camels. The serum activity of alkaline phosphatase, γ-glutamyl transferase and creatine kinase increased significantly in diseased camels compared to healthy camels. In conclusion, camels with trypanosomosis have metabolic acidosis, and the HCO3 was lower than healthy camels. The PCO2 was higher, while PO2, BE, HCO3, TCO2 and SO2 were lower in camels with trypanosomosis compared to healthy camels.
