The fact that there are non-pilus adhesins in a variety of pathogens
is well established.  These include various outer membrane proteins
that are not pili, but that contribute to adherence.  N. gonorrhoeae
opacity proteins contribute to non-pilus mediated adherence.  P. aeruginosa
has one or more non-pilus adhesins, which may be more important in the
organisms' ability to bind to mucins, while pili may be more specific
for epithelial cell binding (hey Reuben, are you here?)
Gram positives (Listeria, streptococci, etc),bhave specific adhesins
as well.  Take a look at the literature--there's a lot that will answer
your question.
