Detection of Salmonella Enteritidis (SE) bacterin in environmental samples from poultry houses using the RapidChek SE immunoassay.

Environmental swabs from pullet houses were tested for the presence of Salmonella Enteritidis (SE) using the RapidChek SE immunoassay test. Of the 1162 samples tested in 2011, 20 samples were positive, but only two samples were confirmed positive for SE by culture. Seventeen positive samples were from pullet houses that had been vaccinated with SE bacterin 2 to 3 days prior to submission to the lab.

Evaluation of human immunodeficiency virus and hepatitis C telemedicine clinics.

Background: Geographical barriers to subspecialty care may prevent optimal care of patients living in rural areas. We assess the impact of human immunodeficiency virus (HIV) and hepatitis C telemedicine consultation on patient-oriented outcomes in a rural Veterans Affairs population.

Methods: This was a pre- and post-intervention study comparing telemedicine with in-person subspecialty clinic visits for HIV and hepatitis C.

Modulation of virulence gene expression in Staphylococcus aureus by interleukin-1beta: novel implications in bacterial pathogenesis.

The effect of IL-1beta on Staphylococcus aureus was investigated in terms of mRNA expression profile of bicomponent leukotoxins (Luk ED, Luk PV, HlgA, and HlgCB) as well as microbial surface components recognizing adhesive matrix molecules (MSCRAMMs). Upon exposure to higher concentrations of IL-1beta, S. aureus expressed significantly higher levels of MSCRAMMs mRNA [fibronectin-binding protein (FnBp), fibrinogen-binding protein or clumping factor (Clf), and collagen-binding protein (Cna)] and had significantly lower expression of mRNAs for bicomponent leukotoxins.

Campylobacter jejuni strains compete for colonization in broiler chicks.

Campylobacter jejuni isolates possess multiple adhesive proteins termed adhesins, which promote the organism's attachment to epithelial cells. Based on the proposal that one or more adhesins are shared among C. jejuni isolates, we hypothesized that C.
