FIG. 2.

Detection of chlamydial DNA subsequent to infection in NOS2^−/− and NOS2^+/+ mice. PCR followed by Sb hybridization of amplicands was used to detect the presence of MoPn ompA DNA in genital swab extracts (days 4 to 126 postinfection) or in extracts of UGT tissues (day 127). (Top row) Results for sequential samples collected from a single NOS2^−/− mouse. (Bottom row) Results for samples collected from a single B6129F1 NOS2^+/+ mouse. Shown are typical individual results that are summarized in Table 2. Administration of Cy was initiated at day 120 postinfection.
