The severity of anaemia was not often proportional to the degree of parasitaemia. The total leucocytes counts showed leucocytosis (25.09 per cent) or an inclination towards leucopenia (19.72 per cent) and the differential leucocyte counts indicated lymphocytosis (44.94) and neutrophilia (16.19). Local cattle had marked leucocytosis and buffaloes showed leucocytosis with neutrophilia. Top Keywords Theileria annulata, Parasitaemia, Haemoglobin, Blood cell counts, Cattle, Buffaloes. Top |
