Adverse Effects of Larkspur (Delphinium spp.) on Cattle
There are numerous species of larkspur (Delphinium spp.) in North America. Larkspurs are a major cause of cattle losses on western ranges in the USA, especially on foothill and mountain rangelands. The toxicity of larkspur species is due to various norditerpenoid alkaloids. In this article, we review the current knowledge regarding larkspur ecology and distribution, analytical technologies to s...

15 صفحه اولConditioning Sheep to Graze Duncecap Larkspur (Delphinium occidentale)
Sheep are more resistant than cattle to larkspur poisoning and thus may be used as a biological tool to graze larkspur to reduce cattle poisoning. Sheep readily graze larkspur in its mature stages, but if they are to be an effective management tool, they must graze it in the early growth stages before cattle enter the allotment. The objective of this study was to determine if sheep could be pos...

15 صفحه اولMolecular characterization of environmental Cladosporium species isolated from Iran
Background and Purpose: Cladosporium species are ubiquitous, saprobic,dematiaceous fungi, only infrequently associated with human and animal opportunisticinfections. Materials and Methods: Airborne samples were collected using the settle plate method, and soil samples were obtained from a depth of 5-10 cm of the superficial soil layer. Samples were cultured on Sabouraud dextrose agar (SDA) pla...
