I have a data set of pairwise interactions (present / absent) among 50 bacteria and I want to visualize their interactions in a network. What can I do? What program or software do you think I can use?
Cytoscape would be the ideal choice. If you prepare your data as a tab-separated pairwise interaction table (each line containing a pair of interacting microbes) you can import this as a set of 'edges' easily.

You can also try the MENA Pipeline http://ieg2.ou.edu/MENA/login.cgi; you have to register- afterwards it's straight forward to get an output file for the visualization in Cytoscape.
Cytoscape is good choice, but I recommand Gephi to visualization the network. Furthermore, network and WGCNA package is great way to make network analysis.
I didn't really get your question or the design of your experiment. Could you explain it briefly? Since I am using an R script which even gives you the statistically significant interactions.
