Pan proteomei This proteome is part of the Histophilus somni (strain 2336) (Haemophilus somnus) pan proteome (fasta)

Haemophilus somnus is the cause of a variety of systemic diseases in cattle, including thrombotic-meningoencephalitis, pneumonia, abortion and other reproductive diseases, arthritis, myocarditis, and septicemia. Diseases due to H. somnus account for millions of dollars in losses to the cattle industry, and are particularly prevalent in feedlots; additionally this agent may also affect dairy cattle. It may be the most economically important pathogen of feedlot cattle.

H.somnus 129Pt is an avirulent commensal strain. Extensive comparisons between 3 available Haemophilus were performed (H.somnus 129Pt, H.influenzae Rd and H.ducreyi 35000HP). It encodes the shikimate pathway for chorismate biosynthesis and all components of the ubiquinone and menaquinone synthesis pathways, as well as genes involved in lipooligosaccharide biosynthesis, carbohydrate uptake and metabolism, cation transport, amino acid metabolism and so on, that may be important to its ecological niche.
