Out of two hundred males during of breeding season, a total of 26 (13%) of microscopically positive flagellated protozoan and 27 (15.5%) of card agglutination test (CATT) positive trypanosomiasis were considered as sub clinically infected animals. The results revealed some decreased measured values related to erythrocyte in the periods of breeding season of infected animals. The leukogram results showed significant increase in total leukocytic count (TLC) and lymphocyte % in infected group comparing with non-infected group during periods of breeding season. Monocyte% and neutrophil% were significantly lower while, eosinophil % showed increase (P<0.01) in infected camels in initial and mid breeding season. Results showed decrease in total proteins (P<0.05) and albumin (P<0.01) during mid-breeding while increased values (P<0.05) of globulin level in initial breeding period were recorded in infected animals. Triglyceride and total cholesterol significantly increased in T. evansi infected camels in mid and late breeding periods. Increased levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine kinase (CK) and total bilirubin were recorded (P<0.01) in infected camels in the different breeding periods. However, alkaline phosphatase (ALP) level was significantly decreased (P<0.01). The present study concluded that subclinical infection of camels with T. evansi can affect some hematological and biochemical parameters related to liver, kidney, hematopoiesis and immune status during late period of breeding season.
