Dear Burkhard,

   Unfortunately there are quite a few things that can go wrong with the
assay.  You would really need to describe a bit more your symptoms to
hazard a guess.  I find it useful to have a beta-gal expressing virus as
the positive control, then stain with X-gal to make sure the infection
works and plaques are the proper size.
