We have established an in vitro model of long-term continuous
Chlamydia pneumoniae infection in HEp-2 cells. Using
transmission electron microscopy, we demonstrated the presence of
spontaneous abnormal chlamydial inclusions similar in appearance to the
persistent chlamydial forms induced in vitro by treatment with
cytokines or antibiotics or by nutrient deprivation.
