The Diagnosis of Syphilis by the General Practitioner (USPHS, 1943)
Primary stage: The characteristic lesions of early syphilis are shown on the penises of infected men and in the genital area of women. Gloved hands palpate a penis for interior chancre; a woman is vaginally examined with the aid of a speculum and a cervical sample is taken with a swab. Lip and finger chancres are shown. Non-syphilitic lesions of the penis are shown. Diagnosis by repeated blood tests of all persons with suspect lesions is required. The taking of a smear for dark field examination is shown. The spirochaeta is shown under the microscope on a dark field.
