Seroprevalence of Neospora caninum and Some Hematological and Biochemical Parameters in Sheep, Mosul-Iraq

T the present study to determine seroprevalance of Neosporacanniunm in serum of sheep by using different serological tests; rapid test and indirect Enzyme Linked Immuno Sorbent Assay (iELISA) in addition to study the changes in some hematological and biochemical parameters accompanied with Neosporacaninum in sheep. Methods : Rapid test and indirect ELISA inthe addition to study of changes in some hematology,and biochemical parameters accompanied with Neosporacaninum in sheep. Results : The study included an examination of 133 blood samples in different areas of Mosul city. Results showed that the prevalence of IgG of Neosporosis by using rapid test and iELISA were 18.04% and 21.05% respectively. Hematology assessment showed no changes in Total Red Blood Cells, Hemoglobin, Packet Cell Volume (PCV), but significant increase in Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), and Mean Corpuscular Hemoglobin Concentration (MCHC). In contrast it shows a significant increase in Total White Blood Cells in comparison with control. There was a significant increase in AST, ALT, CRP and Cholinesterase. All these parameters examined on seropositive sera for rapid test and iELISA in compared with seronegative . Conclusion: Presence of Neosporacaninum in sheep in Mosul cityare diagnosed by both applied diagnostic methods, fast test and iELISA and gave a good result, in addition, to the detection of IgG, hematological and biochemical parameters in the infected sheep.
