Locoweed (Astragalus lentiginosus) fed to mature rams induced transient degenerative changes in the seminiferous, epididymal and vas deferens epithelium. There were changes in behavior and loss of condition in the treatment rams. Observed libido was reduced. Estimated percent abnormal sperm was

About 200/2500 Spanish goats foraging on mountain rangelands of western Montana developed neurologic disease with severe rear limb weakness, knuckling of the rear fetlocks, and a hopping gait. Sick goats were of all ages and in good flesh, though they often had dull, shaggy coats. Some mildly

To better characterize and compare the toxicity of and lesions produced by locoweed (Astragalus mollissimus) with those of swainsonine and a related glycoside inhibitor, castanospermine, 55 Sprague-Dawley rats were randomly divided into 11 groups of five animals each. The first eight groups were

Locoweed is a perennial herbaceous plant included in Astragalus spp. and Oxytropis spp. that contains the toxic indolizidine alkaloid swainsonine. The livestock that consume locoweed can suffer from a type of toxicity called locoism. There are aliphaticnitro compounds, selenium, selenium compounds,

Locoweeds are perennial herbaceous plants included in Astragalus spp. and Oxytropis spp. that contain the toxic indolizidine alkaloid swainsonine. The livestock that consume locoweed feeding can suffer from a type of toxicity called "locoism." There are aliphatic nitro compounds, selenium, selenium

Incorporation of N-acetylglucosamine-specific agglutinins from wheat germ (Triticum aestivum; WGA), thorn apple (Datura stramonium) or nettle (Urtica dioica) rhizomes in the diet at the level of 7 g/kg reduced the apparent digestibility and utilization of dietary proteins and the growth of rats,

Prayer plants (Maranta spp.), which are indigenous to Brazil, are commercially produced in nurseries mainly to be sold as potted houseplants. However, in frost-free areas, they are also used as a ground cover. In March 2009, the Division of Plant Industry in Gainesville, FL received cuttings of

Swainsonine (SW) is the principal toxic ingredient of locoweeds, which can cause intensive vacuolar degeneration because of α-mannosidase inhibition after animal ingestion. While SW can lead to obvious liver damage in vivo, the mechanism of hepatotoxic damage caused by SW is not clear. Therefore,

BACKGROUND Livestock that consume locoweed exhibit multiple neurological symptoms, including dispirited behavior, staggered gait, trembling, ataxia, impaired reproductive function and cellular vacuolar degeneration of multiple tissues due to toxicity from plant-derived alkaloids such as

The thoracic ganglia of insects exhibit a highly ordered organization. It seems possible that the information underlying the emergence of this order during development and its maintenance throughout insect life is given via a distinct pattern of molecules distributed within the ganglion. The

Parietal cells undergo a differentiation process while they move from the isthmus toward the pits and the base region of the gastric gland. The aim of this work was to analyze the rat gastric glands by lectin histochemistry to show the glycans expressed by upper (young) and lower (old) parietal

In September 2002, several unthrifty Verbena canadensis 'Homestead purple' plants were received at the Division of Plant Industry in Gainesville, FL. Symptoms included very subtle yellowing and distortion or stunting of the younger leaves, symptoms that could be overlooked as a nutritional problem.

Lisianthus necrosis virus (LNV) was first identified as a fungus-borne virus that induced systemic necrosis in lisianthus (Eustoma russellianum) in Japan (2). In Taiwan, LNV causes systemic bright yellow chlorosis followed by necrosis in lisianthus (1). The disease was able to spread through the

Since November 2001, geminivirus-like symptoms (stunting, reduced leaf size, and leaf curling "chino") have been observed in tomato (Lycopersicon esculentum Mill.) plantings in Baja California Sur, Mexico. Samples of symptomatic plants were collected from commercial fields and analyzed by

Swainsonine (SW) is an indolizidine triol plant alkaloid isolated from the species Astragalus, colloquially termed locoweed. When chronically ingested by livestock and wildlife, symptoms include severe neuronal disturbance. Toxicity to the central and peripheral nervous system is caused by
