Haemophilus is a genus of Gram-negative, pleomorphic, coccobacilli bacteria belonging to the family Pasteurellaceae. (wikipedia.org)
While Haemophilus bacteria are typically small coccobacilli, they are categorized as pleomorphic bacteria because of the wide range of shapes they occasionally assume. (wikipedia.org)

Species9
Members of the genus Haemophilus usually will not grow on blood agar plates, as most species require at least one of these blood factors for growth: hemin (X-factor) and/or nicotinamide adenine dinucleotide (V-factor). (wikipedia.org)
Clinical laboratories use tests for the requirement of the X and V factors to identify the isolates as Haemophilus species. (wikipedia.org)
The species Haemophilus haemoglobinophilus is an exception to this, and has been shown to grow well on both blood and chocolate agars. (wikipedia.org)

ColE1 plasmids are small mobilizable replicons that play an important role in the spread of antibiotic resistance in Pasteurellaceae In this study, we describe how a natural single nucleotide polymorphism (SNP) near the origin of replication of the ColE1-type plasmid pB1000 found in a Pasteurella multocida clinical isolate generates two independent plasmid variants able to coexist in the same cell simultaneously.

Members of the genera Haemophilus and Aggregatibacter are closely related and not always cleanly distinguished using short fragments of the 16S ribosomal RNA gene. (ehomd.org)
These three genera are grouped together in the family Pasteurellaceae, the members of which are obligate parasites of vertebrates. (anipedia.org)
