*Stress leucogram, characterised by '''neutrophilia''', '''monocytosis''', '''eosinopenia''' and '''lymphopenia'''.  A similar pattern may occur with hyperadrenocorticism (Cushing’s disease) or exogenous corticosteroid therapy as these hormones selectively suppress lymphocytic activity and the inflammatory response in general.  Young horses may develop lymphopenia when exposed to even mild stress, such as handling.
