Classification
Higher order taxa
Haemophilus somnus is a bacteria under the phylum proteobacteria. It is of the class, Gammaproteobacteria, in the order Pasteurellales, which typically live on the mucosal surface of birds and mammals, most notably in the upper respiratory tract. They are also of the family Pasteurellaceae. genus Histophilus

Genus species
Description and significance
Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.
Genome Structure
Their genome (seq: RS: NC_008309) consists of a circular chromosome containing 2007700 base pairs and a plasmid(pHS129) is approximately 5178 bp in length. It is made up of roughly 34% GC content and 66% AT and contains genes coding for approximately 1798 different proteins and 65 RNA genes.
Cell structure and metabolism
Haemophilus somnus is a rod-shaped, gram negative bacteria. It is a facultative pathogen that has LOS is its major outer membrane component. It also contains bacterial transferrin receptors, which is a structure that contributes to its virulence (typically in cattle). Haemophilus has no flagella and is catalase negative.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
