Inducible Nitric Oxide Synthase Does Not Affect Resolution of Murine Chlamydial Genital Tract Infections or Eradication of Chlamydiae in Primary Murine Cell Culture

Mice lacking inducible nitric oxide synthase (iNOS) or treated with iNOS inhibitors resolved chlamydial genital tract infections. Additionally, treatment of primary murine cell cultures with gamma interferon restricted chlamydial growth in the absence of nitric oxide. From these results, iNOS activity is unnecessary for the resolution of chlamydial genital tract infections in mice and inhibition of chlamydial growth in culture.
