The morphological examination of the ova and immunoserological examination yielded typical findings of P. miyazakii. Treatment with praziquantel improved his chest radiographic findings and a decrease of serum total IgE, as well as the values of immunoserological examination for P. miyazakii. The clinical course of this patient indicated that he had been infected with P. miyazakii for 7 years at l...Continue Reading
