We used a scanning electron microscope for identification of the two ticks which were found parasitic on two women.
(1) The patients were women of 69 and 62 years old.The main complaints were a tumour-formation on the skin of the upper abdominal region with itching in one case and the pain at the cicatrice of a past operation of the chest in another.In both cases a purulent inflamation appeared after 7 to 10 days at the site of bite and healed after 10 to 14 days with pigmentation.
(2) In our study through a scanning electron microscope we examined the morphological characters of marginal body setae, porose area, internal as well as external spurs of coxa I, and genital pore. The scanning electron microscope was effective especially to observe marginal body setae, spiracular plate, and internal as well as external spurs of coxa I, which are important for discriminating Ixodes nipponensis from Ixodes persulcatus.
We would expect that the morphological and physiological study of Ixodes species will develop hereafter concurrently with the parasitism of man by Ixodes nipponensis from the epidemiological standpoint.
