Confocal microscopy confirmed that spirochetes were present within the salivary glands and did not represent surface contamination by
midgut contents during dissection (Fig. 5B).
In addition to staining
the midgut contents with FITC - labeled polyclonal anti-Borrelia species antibody, we washed and re-stained this set and stained the second set of xenodiagnostic tick (XT) samples with an anti-OspA monoclonal antibody (CB10, obtained from J. Benach [41]-RRB-, followed by anti-mouse IgG - Alexa 488 (Molecular Probes).
The tick
midgut contents were also subjected to RT - PCR.
A portion of the XT
midgut contents were also placed in culture.
