You could try the ribosomal database project. Do a google search and
you'll find it. It contains every ribosomal sequence in the databases,
and it draws trees on the fly with any species you choose from the list.
There's a lot in there, so it can take a while to do it's thing sometimes (:
Otherwise, you can do it yourself by downloading the 16S sequence(s)
from species and strains that you're interested in, and doing a multiple
alignment, then generating a tree from that. You can get the sequences
from genbank, do the alignment with clustalw or clustalx (either
download it or use a web-based version), then use treeview to calculate
and draw trees from it.
