Ultrastructural studies of chlamydia‐infected air sacs of chicks [PDF]
Avian Pathology, 1992 The air sac of chicks inoculated with Chlamydia psittaci was examined ultrastructurally. The epithelial cells had minute chlamydial inclusion bodies consisting of a few reticulate bodies in the initial stages of infection. In the epithelial cells in the early and middle stage of infection, small- to medium-sized chlamydial inclusion bodies were found ...
