64. A study on immunological response of leukocytes to ticks in cattle reared in sub-tropical region of Khyber Pakhtunkhwa Pakistan
Abstract
Parasitic infestation in cattle is a common phenomenon in sub tropical conditions of Khyber Pakhtoonkhwa. The present study was designed to investigate the immune response of differential leukocytes count (lymphocytes, monocytes, eosinophils, basophils and neutrophils) against ticks in cattle under sub tropical conditions in the hilly areas of northern Khyber Pakhtunkhwa, Pakistan. A total of 40 tick infested cattle were divided into four age groups having 10 animals in each group i.e. G1 (3 years), G2 (4 years), G3 (5years) and G4 (6 years) were evaluated on the basis of different leukocyte count. The overall means counted in the present study were 3144.97±736.62 mm3, 543.03±93.28/mm3, 610.37±154.60/mm3, 51.4±7.38mm3 and 32069.175±273.18/mm3 for total lymphocytes, monocytes, eosinophils, basophils and neutrophils respectively. There was non-significant association was recorded among different age groups on differential leukocytes count in tick infested cattle except on eosinophils count. As a result it was concluded that there is poor immune response of leukocytes to ticks except eosinophils in cattle.
