lolium arundinaceum/necrosis

Extracts of annual ryegrass (Lolium rigidum) infected with Anguina sp. and Corynebacterium sp., and associated with an outbreak of annual ryegrass toxicity in sheep, were administered to 2-week-old rats by a single intraperitoneal injection. Rats that received a lethal dose of toxin developed

Annual ryegrass (Lolium rigidum) parasitised by Anguina agrostis and Corynebacterium rathayi causes neurological signs and brain lesions thought to be associated with a vasoconstrictor effect of the toxic grass. In three separate experiments of six to 112 days duration parasitised ryegrass was fed

Outbreaks of clinical disease caused by the ingestion of ergotized Lolium rigidum (annual ryegrass), which resulted in a substantial loss in production, have been reported. A number of outbreaks of a hyperthermia syndrome in cattle, characterized by severe loss in milk production, loss of body mass

BACKGROUND Naphthoquinones are known for their broad range of biological activities. Given the increasing demands of consumers in relation to food quality and growing concerns about the impact of synthetic herbicides, it is necessary to search for new agrochemicals. Natural products and allelopathy

OBJECTIVE To investigate whether Mediterranean tall fescue (Lolium arundinaceum (Schreb.) Darbysh. (syn Festuca arundinacea)) infected with selected fungal endophytes (Epichloë coenophiala (formerly Neotyphodium coenophialum)) caused equine fescue oedema when grown in New Zealand, and to examine the

The aims of this study were to explore whether a phenolic acid and flavonoid fraction (named PAFF) isolated from Lolium multiflorum Lam. protects against d-galactosamine (GalN)-induced liver damages in mice and to investigate the associated mechanisms. ICR mice received oral administration

A large panel of human CD4+ T helper (Th) cell clones with established Th1, Th2, or Th0 profiles of cytokine secretion were examined for the expression of CD30, a member of the tumor necrosis factor receptor superfamily. Th1 clones expressed poor or no CD30 mRNA, and showed low or undetectable

Wastewater from phosphate fertilizer industry that contains essentially a significant amount of both fluoride and phosphate was treated by separative precipitation of fluoride ions with hydrated lime. Thus, a phosphate-rich effluent with low content of fluoride was obtained. The microtoxicity of the

Fungal diseases of annual ryegrass (Lolium multiflorum Lam.), a cool-season species grown for forage and turf in the southeastern United States, and bermudagrass (Cynodon dactylon (L.) Pers.), a warm-season perennial, usually are considered distinct. In May 2002 and 2004, symptoms of leaf and stem

Bipolaris sorokiniana (Sacc.) Shoemaker is a major foliar and root-infecting pathogen of cool-season forage and turf grasses and small grains in the southeastern United States (2). In North America, B. sorokiniana has been reported from bermudagrass (Cynodon dactylon [L.] Pers.) once in California

High throughput sequencing technologies were used to identify plant viruses in cereal samples surveyed from 2012 to 2017. Fifteen genome sequences of a tenuivirus infecting wheat, oats and spelt in Estonia, Norway and Sweden were identified and characterized. Like most tenuiviruses, the genome of

Fescue toxicosis is a common syndrome of poor growth and reproductive performance of beef cattle grazing endophyte-infected tall fescue infected with Lolium arundinaceum Schreb. Together with decreased feed intake, decreased growth rates and tissue necrosis due to vasoconstriction, depressed
