Clavibacter michiganensis subsp. sepedonicus is a gram positive bacteria (Li and Deboer, 1995). It is pleomorphic, slightly club-shaped short rod and this rod size is about 0.5 - 1.0 µm. C.m. sepedonicus is aerobic pathogen but it also can grow slowly in anaerobic condition. The isolated colonies are often yellow, creamy and smooth (Van der Wolf J.M et al, 2005). | |||

Clavibacter michiganensis subsp. sepedonicus is a gram positive bacteria (Li and Deboer, 1995). It is pleomorphic, slightly club-shaped short rod and this rod size is about 0.5 - 1.0 µm. C.m. sepedonicus is aerobic pathogen but it also can grow slowly in anaerobic condition. The isolated colonies are often yellow, creamy and smooth (Van der Wolf J.M et al, 2005). C.m. sepedonicus infects the healthy plant through wounds. It moves from plant to plant in irrigation water or insect vectors such as Colorado potato beetles and flea beetles. C.m. sepedonicus is soil invader pathogen. The pathogens overwinter in tuber seeds and favor in high temperature at the end of growing season. It can survive in tuber seeds, plant debris and on agricultural equipments. It can survive up to 10 days in surface water and up to 5 years in dried and cold climate (Sparks A. and Megan K., 2008) and. However, if the temperature increases up to 150C, the pathogen can survive only for few weeks (Van der Wolf J.M. et al, 2005). The C.m. sepedonicus gene was found 90% identity of Clavibacter michiganensis subsp. Michiganensis. This gene was found in a protein which was coded from over 700 amino acids (Van der Wolf J.M et al, 2005).
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
