At my previous job, we plated BAP's along with the LIM broth and never found the
scenario you described.  If anything the BAP's missed GBS and the LIM's grew it,
which is what they are for anyway.  If a doc ordered a group B screen, the swabs
went directly into LIM.  I've never heard of Group D inhibiting GBS.  I'll have to
ask our Ph.D. about that one.

We don't look for GC in a genital IF the patient has an LCX probe ordered for
Chlamydia and GC (don't plate TM that is).  A full genital culture without an LCX
gets a TM.  We look for yeast, Staph. aureus, GC, G. vaginalis, GBS.  A pure
culture of enterics gets ID/Sensi, but if there's a mixture, we don't do anything
with it.  Hemophilus gets worked up and the doc has to decide, I guess.  At my
previous job, only mod. to lg. amt of yeast, Staph. aureus, G.vag. got worked up.
Enterics were reported "lg. amt. GNR, ID if requested" and they NEVER requested
them.  It depends on where you work.  I work at a hospital based lab now, so
guidelines are a little different.

Speaking of work, I've got to leave NOW.  Keep in touch.
