Immunoelectron-microscopic quantitation of differential levels of chlamydial proteins in a cell culture model of persistent Chlamydia trachomatis infection

Abstract

Electron immunolabeling techniques were used for quantitative evaluation of alterations in the steady-state levels of chlamydial antigens in persistent Chlamydia trachomatis cultures. Gamma interferon-mediated persistent chlamydial development correlated with an increase in the levels of the chlamydial heat shock protein (hsp60) and with a significant reduction in the levels of the major outer membrane protein.
