Spec. Char.:
Disease:Septicemic disease in poultry
Hosts:
Clinical Picture: Lesions in multiple organs, such as salpingitis and oophoritis
Virulence Factors: G. anatis has a large RTX-like toxin (GtxA), which induces a strong leukotoxic effect on avian macrophages. Furthermore, this bacterium also has a capsule and fimbriae.
