  1. The bacterial groups that are part of the networks are listed along with the number of genes with which they are highly correlated. Several genes are shared between bacterial groups. Both the genes and the bacterial groups are significantly different either in time or treatment between the control. The first seven groups are common between the three networks. Some general information on these bacterial groups is also given in the last column
