Clavibacter toxicus

Clavibacter toxicus

bacterial species (formerly Corynebacterium rathei) that grows in galls caused by grass nematodes (Anguina spp.) on the seedheads of some temperate zone pasture grasses, e.g. Agrostis avenacea, Lolium rigidum, Polypogon monspeliensis, and produces a highly potent toxin (corynetoxin = tunicamycin) which causes sudden death in cattle.
