Table 4 Prophage sequences present in sequenced clostridial genomes. Pvalue – p-value in Fisher’s exact test, padjust – p-value, adjusted for multiple hypothesis testing, odds ratio – odds of recurrent infection, %single/recurrent – percentage of sequences with prophage present in single/recurrent infections. Adjusted p-values < 0.05 were considered significant
