Material type: materialTypeLabelBookPublisher: 1996Subject(s): Department of ParasitologyDDC classification: 0511,T Dissertation note: This study was contemplated to evaluate some aspects of prevalent species including taxonomy of Eimeria infection& in young cattle and buffalo calves. In addition the effects of Eimeria infections on various haematological parameters i.e., Haemoglobin, PCV, RBC count, ESR and Differential leucocyte count were also studied. For this purpose the animals (Buffalo and Cattle calves) were divided into two groups. Firstly those having diarrhoea and secondly those which were apparently healthy. The buffalo and cattle calves were divided into four groups (A, B, C and D) on the basis of the age in days under the maximum age of 120 days. A group ranged from 1-30 days, B ranged 31- 60 days, C ranged 61-90 and D ranged 91-120 days. The haematological observations were recorded from both the groups formulated upon the basis of age as A, B, C and D in both cattle and buffalo calves and findings compared with the control groups A, B, C and D having the same age range. Results revealed that out of 816 animals (442 cattle and 374 buffalo calves), 167 (84 cattle and 83 buffalo calves) were found to be positive (20.46%) for Eimeria species infection. Whereas 62 out of 250 (24.80%) suffering from diarrhoea and 22 out of 192 (11%) apparently healthy cattle calves showed coccidial infections. For buffaloes 63 out of 220 cases (29%) were positive from animals showing diarrhoea and 20 out of 154 (13%) were found positive for coccidiosis from apparently healthy group. Four species of Eimeria namely, Eimeria zuernii, Elmerip bovis, Eimeria cylindrica and Eimeria ellipsoidalis were found in the above mentioned ca1ves E. zuernhi was the most prevalent species found (48%) followed by . bovis (27%), Eimeria cvlindrica (16%) and Eimeria ellipsoidalis (10%) respectively. OPG count carried out ranged from 2500-70,000 oocyst per gram of faeces. Haematological observations showed anaemia, which was a feature of the diarrhoeic calves and not found in apparently healthy animals although some of them had been harbouring Eimeria infection. The PCV decreased proportionately with haemoglobin whereas erythrocyte count also showed decrease in positive cases. On the other hand ESR of the above referred calves increased. There was neutrophilia in the infected animals versus control animals and lymphocytes decreased in infected animals. There was no significant change in eosinophil and monocyte counts.

This study was contemplated to evaluate some aspects of prevalent species including taxonomy of Eimeria infection& in young cattle and buffalo calves. In addition the effects of Eimeria infections on various haematological parameters i.e., Haemoglobin, PCV, RBC count, ESR and Differential leucocyte count were also studied. For this purpose the animals (Buffalo and Cattle calves) were divided into two groups. Firstly those having diarrhoea and secondly those which were apparently healthy. The buffalo and cattle calves were divided into four groups (A, B, C and D) on the basis of the age in days under the maximum age of 120 days. A group ranged from 1-30 days, B ranged 31- 60 days, C ranged 61-90 and D ranged 91-120 days. The haematological observations were recorded from both the groups formulated upon the basis of age as A, B, C and D in both cattle and buffalo calves and findings compared with the control groups A, B, C and D having the same age range.

Results revealed that out of 816 animals (442 cattle and 374 buffalo calves), 167 (84 cattle and 83 buffalo calves) were found to be positive (20.46%) for Eimeria species infection. Whereas 62 out of 250 (24.80%) suffering from diarrhoea and 22 out of 192 (11%) apparently healthy cattle calves showed coccidial infections.

E. zuernhi was the most prevalent species found (48%) followed by . bovis (27%), Eimeria cvlindrica (16%) and Eimeria ellipsoidalis (10%) respectively. OPG count carried out ranged from 2500-70,000 oocyst per gram of faeces.
