The nature of the Halberstaedter-Prowazek inclusion bodies,² found in epithelial scrapings from patients with trachoma, was discussed in a recent report;^1c on the basis of microscopic evidence, the conclusion was supported that the inclusion bodies of trachoma were intracellular colonies of a virus which might be the etiologic agent of the disease. The virus was found to be identical morphologically with the virus of inclusion blennorrhea³ and strikingly similar to the virus of psittacosis.⁴ Like these viruses it occurred in two phases: the large, initial body (Lindner) phase and the small, elementary body phase.
