Trachoma.— The etiology of trachoma— contagious granular con- 
junctivitis characterized by the formation of small granular elevations 
of the eyelids that atrophy and lead to scar formation— is not defi- 
nitely settled. 
HalberstJidter and von Prowazek^ have described endocellular bodies 
lying within the conjunctival epithelium and usually near the cell 
nuclei, which are minute oval or round granules frequently occurring 
in pairs, of somewhat variable size, but smaller than ordinary cocci. 
They are typically enclosed in a somewhat indefinitely defined homo- 
geneous matrix which is regarded as a reaction product. The earlier 
lesions contain moderate-sized oval or round bodies which stain a 
faint bluish color with Giemsa's stain; later very minute oval or 
spherical bodies appear, which color reddish with the same stain. 
These observations were soon confirmed. Somewhat later the same 
investigators described inclusions in the conjunctival epithelium of 
uncomplicated cases of blennorrhea neonatorum which were prac- 
tically identical histologically with those described. This observation 
naturally led to new investigation of the subject.
