HUMAN TOXOPLASMOSIS

Abstract

Toxoplasmosis as a disease of man is of recent recognition.¹Not many cases have been reported;²of these relatively few have been proved by the actual demonstration of the parasite microscopically and by animal inoculation. Of the known instances of human infection recovery has occurred in but a single case, that of a boy with acute encephalitis.³Moreover, only 3 cases involving adults are on record.⁴It seemed worth while, accordingly, to describe the demonstration of toxoplasma⁵(by the technics of histopathologic analysis and animal inoculation) in tissue removed by biopsy from a white man during his convalescence from an acute febrile illness. This patient recovered without apparent sequelae and has been working for several years up to the present time. <h3>REPORT OF CASE</h3><h3>History.—</h3> M. B., a man aged 65, Jewish, a tailor, was admitted to the Strong Memorial Hospital on Nov. 30, 1942,
