STRING analysis of predicted interactions between proteins encoded by genes differentially regulated by the fecal extract

A. Network of genes downregulated at least tenfold during growth in the presence of the fecal extract. Green circles indicate a cluster of genes related to chemotaxis and motility in V. cholerae, with red circles representing genes unrelated to these functions. B. Network of genes upregulated at least tenfold during growth in the presence of the fecal extract. Green circles indicate genes related to sulfur metabolism, whereas red circles represent genes in other categories.
