Genome sequences of Haemophilus haemolyticus, including haemin-independent strains

Comparative genome analysis characterised a lineage of Haemophilus haemolyticus that produce their own haemin (X-factor). Haemophilus spp. strains informally-classified as “H. intermedius subsp. intermedius” also reside in this lineage, thus leading to their re-classification as (haemin-independent) H. haemolyticus.
