The gene content of Haemophilus spp. genomic islands. Forty-three genes, comprising mostly the putative replication and transfer modules, constitute an essential set of core genes for genomic islands of human oropharyngeal Haemophilus spp. Numbers (white) in the table represent the position of the gene in the respective genomic island. ICE, integrative and conjugative element; Tn, transposon.
