Clinical and Haematobiochemical Changes in Cattle with Theileria orientalis Infection

Abstract

Out of 110 animals suspected for theileriosis, 100 cattle were positive for T. orientalis infection. The predominant clinical signs were tick infestation (45%), anorexia (80%), pyrexia (22%), swollen lymph node (83%), pale conjunctival mucous membrane (73%), nasal discharge (65%), bruxism (43%), dyspnoea (67%), tachycardia (71%), reduced milk yield (62.35%) and lameness (12%). Haematological analysis revealed significant (P<0.05) decrease in haemoglobin (Hb), haematocrit (PCV), red blood cells (RBC) and platelets and significant (P<0.05) increase in mean corpuscular volume and eosinophil count. Serum biochemistry revealed significant (P<0.05) reduction in mean serum albumin and albumin: globulin ratio and significant (P<0.01) increase in mean total protein and globulin was observed in Theileria infected cattle to the control.
