Material type: materialTypeLabelBookPublisher: 2002Subject(s): Department of ParasitologyDDC classification: 0727,T Dissertation note: Ticks infestation and piroplasmosis are serious problems of domestic cattle. The present study was conducted to find out the prevalent species of ticks and the piroplasms transmitted by these ticks. The effect of ticks and blood parasites on various blood parameters was also studied. The parameters included: RBC count, WBC count, Haemoglobin (Hb) estimation, erythrocytic sedimentation rate (ESR) and differential leukocytic count (DLC). The study was conducted from June to August, 2001. A total of 80 cattle (40 local nondiscript cattle and 40 crossbred) were selected. Each type was divided into four groups i.e. A, B, C and D. The cattle of group-A were free from any infestation/infection. The animals of group B were only tick infested. Animals of group-C were only piroplasm infected and the animals of group-D were infested with ticks and the piroplasms. Each group from both the breeds consisted of 10 animals. Haemotological examination revealed a significant decrease (P<0.05) in TEC, Hb and TLC in groups B, C and D as compared to group-A relating to each breed. The lymphocytes were decreased from normal in all test groups in both the breeds, significantly. However, neutrophil and eosinophils were increased significantly in test groups as compared to control group (A). The values of erythrocytic sedimentation rate (ESR) showed a significant increase in groups B, C and D of both types of cattle as compared to the control group (A). The overall results showed that the effect of mixed infection on haematology was greater than the single infection of ticks or piroplasm.
