Footrot is a mixed bacterial infection of the hooves of sheep. The gram-negative anaerobic bacterium Dichelobacter nodosus is the principal causative agent, with different strains causing diseases of different severity, ranging from benign to virulent. In Australia, in the state of New South Wales (NSW), only virulent footrot is subject to regulatory(More)
Francisella tularensis causes disease (tularemia) in a large number of mammals, including man. We previously demonstrated enhanced efficacy of conventional antibiotic therapy for tularemia by postexposure passive transfer of immune sera developed against a F. tularensis LVS membrane protein fraction (MPF). However, the protein composition of this(More)
Saponins are plant glycosides that consist of a steroid, steroid alkaloid or triterpenoid aglycone and one or more sugar chains that are covalently linked by glycosidic binding to the aglycone. Glucose, galactose, glucuronic acid, xylose and rhamnose are commonly bound monosaccharides. Saponins are found in all organs of a variety of higher plants. Due to(More)
This experiment was conducted to study the prevalence of Salmonella and Escherichia coli (E. coli). from the surface of egg shells, egg shell membranes or pores, and internal contents from unwashed eggs collected from commercial caged layer farms in Australia. Egg shell swabs, shell crush and egg internal contents (yolk and albumen) of an individual egg(More)
Effects associated with hyperfine mass splitting between pseudoscalar and vector mesons may induce surprisingly large 1/mQ corrections in the heavy quark expansion. We demonstrate this in a relativistic quark model by calculating to all orders in 1/mQ, with and without hyperfine effects, and comparing to the first order results. Total corrections of 30% or(More)
A simple relativistic model of heavy-quark-light-quark mesons is proposed. In an expansion in inverse powers of the heavy quark mass we find that all zeroth and first order heavy quark symmetry relations are satisfied. The main results are: • the difference between the meson mass and the heavy quark mass plays a significant role even at zeroth order; • the(More)

A simple relativistic model of heavy-light mesons is applied to the rare decay B → K∗γ in the standard model. We find Γ(B → K∗γ)/Γ(b → sγ) = (17±4)% and BR(B → K∗γ) = (4.8±1.9)×10(|Vcb|/.04). These numbers are reduced by only 20% in the heavy-quark limit. We have recently developed a relativistic model of mesons containing a heavy quark Q and a light(More)
