Table 6 Predicted hub proteins from the essential gene lists for C. jejuni (A) and C. coli (B). C. jejuni and C. coli top 10 hub proteins were predicted using Betweenness, Closeness, Degree, Radiality and Bottleneck to rank nodes within the protein-protein interaction networks built from the essential gene lists. The top 10 proteins are in rank order (1 being the highest and 10 being the lowest) according to species and the type of analysis
