  1. Genes showing statistical differences in relation to pathogenic groups were compared for the phylogenetic groups, using Fisher's exact test. *For each comparison, a P value of < 0.05 was considered statistically significant (+), and a P value of > 0.05 was not considered statistically significant (-).
