Antigenic Characterization of <I>Haemophilus somnus</I> Lipooligosaccharide
… membranes, including pathogenic species of <I>Haemophilus</I> and <I>Neisseria</I>. LOS phase variation is one mechanism by which some of these bacteria avoid the host immune response. To better understand LOS phase variation as a virulence mechanism of <I>H. somnus</I>, knowledge of the …

Comparative and Functional Genomic Studies of Histophilus somni (Haemophilus somnus)
Histophilus somni is a commensal of the mucosal surfaces of respiratory and reproductive tracts of cattle and sheep. However, as an opportunistic pathogen, H. somni can cause diseases such as pneumonia, myocarditis, abortion, arthritis, and meningo-encephalitis. Previously, several virulence …

Cloning and Characterization of a Gene Involved in Lipooligosaccharide Biosynthesis in Haemophilus somnus
… lipooligosaccharide (LOS) phase variation in Haemophilus influenzae type b (Hib). In an attempt to identify H. somnus phase-variable LOS genes, the presence of CAAT repeats within the H. somnus 738 genome was confirmed using a (CAAT)7 probe. A 3.9 kb EcoRI fragment that reacted with the probe …

Investigation of Haemophilus somnus Virulence Factors: Lipooligosaccharide Sialylation and Inhibition of Superoxide Anion Production
… strains of the bovine opportunistic pathogen Haemophilus somnus (Histophilus somni) cause multi-systemic diseases in cattle. One of the reported virulence factors that H. somnus may use to persist in the host is resistance to intracellular killing. It is reported in this dissertation that H. …

The Molecular Characterization of Phosphorylcholine (ChoP) on Histophilus somni Lipooligosaccharide: Contribution of ChoP to Bacterial Virulence and Pathogenesis
… of H. somni through sequence homology with Haemophilus influenzae genes. The open reading frame (ORF) of lic1A contained a variable number of tandem repeats of the tetranucleotide unit 5'-AACC-3'. Slipped strand mispairing in the repeat region during replication leads to shifting the …
