Evaluation of some acute phase proteins in cattle naturally infected with Babesia bigemina.
Bovine babesiosis due to Babesia bigemina infection induces systemic inflammation, evidenced by increased sialic acid (SA) levels and declined cholinesterase activity. The current study was undertaken to assess further indicators of the systemic inflammation in the naturally infected cattle. To this end, serum levels of some selected acute phase-proteins (APPs) including serum amyloid A (SAA), haptoglobin (Hp), ceruloplasmin (Cp), and fibrinogen were measured. Additionally, sensitivity and specificity of the APPs were calculated by receiver operating characteristic curve. The correlation among APPs, SA and cholinesterase activity were also assessed. Our previous blood specimens were used to measure APPs. Briefly, the diseased animals were divided into two groups according to the parasitemia: 12 mildly (20 % <) and 8 severely (20 %>) infected animals. Moreover, 10 healthy animals as the control were included. The levels of all APPs were measured to be significantly elevated in a parasitemia burden-dependent fashion as compared to the control. Furthermore, all the APPs showed 100 % specificity, but only SAA and Cp had 100 % sensitivity. A strong and positive correlation was calculated between the APPs and SA; however, cholinesterase activity was inversely correlated with AAPs and SA. In conclusion, inﬂammatory reactions play a pivotal role in the pathogenesis of bovine babesiosis and APPs can be considered as the potential indicators of inflammation.
