Gamma interferon (IFN-
) is an important cytokine in host defense
against chlamydial infection. An in vitro cell culture system was used
to show that IFN-
inhibition of chlamydial growth, as determined by
diminished recovery of infectious elementary bodies, differed markedly
among chlamydial strains. These differences in sensitivity among
chlamydial strains to IFN-
-mediated inhibition may profoundly
influence the clinical outcome of infection.
