A patient who had been working with snakes for many years developed urticarial lesions on contact with the venom of the poisonous rinkals (Haemachates haemachatus). More recently, the patient complained of generalized allergic reactions occurring within minutes of exposure to the venom. The patient's serum, but not control sera, contained IgE antibodies that reacted with the specific snake venom in an ELISA and was demonstrated to associate with a 66 kd component of the venom with Western blotting. With an ELISA, the patient's serum was also demonstrated to contain IgG antibodies to the specific snake venom and to venom from three other snakes with which the patient had previously been in contact. The possibility of an acute allergic reaction should be considered in individuals continuously working with snakes or in individuals who have previously been bitten by snakes. © 1987.
