| 英文描述 | Cattle, sheep, and horses in Australia developed clinical signs, including nervous signs, when grazing grasses carrying corynetoxins produced by the bacterium CLAVIBACTER TOXICUS. When the grass involved in Australia is AGROSTIS AVENACEA the syndrome is known as 'Flood Plain Staggers'; when the grass is POLYPOGON MONSPEILIENS (annual beard grass) the syndrome is known as Stewarts's Range Syndrome. There are no clinical or pathologic findings that can be considered pathognomonic; dx is by history, access to affected grasses, and demonstrating the presence of corynetoxins in affected pasture. High ambient temperature and forced exercise often increased clinical signs, particularly in cattle (Davis et al.). |
