The effect of dietary Echinacea purpurea on performance, viremia, and ontogeny of the humoral antibody response against porcine reproductive and respiratory syndrome virus (PRRSV) infection was evaluated in weaned pigs. In three replicates, 120 weaned pigs (25 +/- 1 d of age; 8.46 +/- 0.48 kg of BW) from a PRRSV-naive herd were allotted randomly to one of eight pens (diets) in two separate room...

This paper reviews the chemistry, pharmacology and clinical properties of Echinacea species used medicinally. The Echinacea species Echinacea angustifolia, Echinacea pallida and Echinacea purpurea have a long history of medicinal use for a variety of conditions, particularly infections, and today echinacea products are among the best-selling herbal preparations in several developed countries.

INTRODUCTION When directly exposed to various echinacea fractions, human leukocytes ex vivo are strongly stimulated to proliferate and to produce immunostimulation and inflammatory cytokines. A comparison of fractions containing lipoidal small molecules and high-molecular-weight water-soluble polysaccharides indicates that the latter are substantially more potent as immunostimulants. Echinacea ...

In this announcement, we detail the draft genome sequence of the Pseudomonas sp. strain Ep R1, isolated from the roots of the medicinal plant Echinacea purpurea The elucidation of this genome sequence may allow the identification of genes associated with the production of antimicrobial compounds.
