The blood picture and serum biochemistry profile of the African pied crow (Corvus albus)

The blood picture and serum biochemistry profile of the African pied crow (Corvus albus) The crow is commonly regarded as an indicator species for the surveillance of important diseases such as West Nile fever and avian influenza, as these diseases had been associated with significant pathology in crows and death of crows in most cases. This study evaluated the blood picture (haematology) and serum biochemistry profile of apparently healthy African pied crows trapped in Nsukka, Eastern Nigeria. A total of 25 crows were used for the study, and the evaluation of the blood picture and serum biochemistry profile followed standard procedures. Results obtained for the parameters assessed are summarised as follows (mean ± standard error): packed cell volume (%)—42.85 ± 0.90, haemoglobin concentration (g/dl)—14.09 ± 0.36, red blood cell count (106/ul)—3.15 ± 0.09, mean corpuscular volume (fl)—137.53 ± 4.00, mean corpuscular haemoglobin (pg)—45.36 ± 1.68, mean corpuscular haemoglobin concentration (g/dl)—33.01 ± 0.82, total white blood cell count (103/ul)—26.04 ± 1.35, heterophil counts (%)—67.99 ± 1.85, lymphocyte counts (%)—28.52 ± 1.85, monocyte counts (%)—1.28 ± 0.21, eosinophil counts (%)—1.59 ± 0.21, basophil counts (%)—0.36 ± 0.11, alanine amino transaminase (IU/l)—51.16 ± 5.00, aspartate amino transaminase (IU/l)—101.42 ± 3.63, serum alkaline phosphatase (IU/l)—31.34 ± 3.35, total protein (g/dl)—3.13 ± 0.13, albumin (g/dl)—1.32 ± 0.08, globulin (g/dl)—1.81 ± 0.14, cholesterol (mg/dl)—165.95 ± 6.63, blood glucose (mg/dl)—295.22 ± 11.20, urea nitrogen (mg/dl)—6.71 ± 0.63, uric acid (mg/dl)—21.44 ± 3.51 and body weight (g)—453.41 ± 9.30.

Abstract

The crow is commonly regarded as an indicator species for the surveillance of important diseases such as West Nile fever and avian influenza, as these diseases had been associated with significant pathology in crows and death of crows in most cases. This study evaluated the blood picture (haematology) and serum biochemistry profile of apparently healthy African pied crows trapped in Nsukka, Eastern Nigeria. A total of 25 crows were used for the study, and the evaluation of the blood picture and serum biochemistry profile followed standard procedures. Results obtained for the parameters assessed are summarised as follows (mean ± standard error): packed cell volume (%)—42.85 ± 0.90, haemoglobin concentration (g/dl)—14.09 ± 0.36, red blood cell count (106/ul)—3.15 ± 0.09, mean corpuscular volume (fl)—137.53 ± 4.00, mean corpuscular haemoglobin (pg)—45.36 ± 1.68, mean corpuscular haemoglobin concentration (g/dl)—33.01 ± 0.82, total white blood cell count (103/ul)—26.04 ± 1.35, heterophil counts (%)—67.99 ± 1.85, lymphocyte counts (%)—28.52 ± 1.85, monocyte counts (%)—1.28 ± 0.21, eosinophil counts (%)—1.59 ± 0.21, basophil counts (%)—0.36 ± 0.11, alanine amino transaminase (IU/l)—51.16 ± 5.00, aspartate amino transaminase (IU/l)—101.42 ± 3.63, serum alkaline phosphatase (IU/l)—31.34 ± 3.35, total protein (g/dl)—3.13 ± 0.13, albumin (g/dl)—1.32 ± 0.08, globulin (g/dl)—1.81 ± 0.14, cholesterol (mg/dl)—165.95 ± 6.63, blood glucose (mg/dl)—295.22 ± 11.20, urea nitrogen (mg/dl)—6.71 ± 0.63, uric acid (mg/dl)—21.44 ± 3.51 and body weight (g)—453.41 ± 9.30.
