Continue the cooperation with Marcus V. Locatelli, this is another interesting article
published on its website and freely translated. Obviously everyone who find some mistakes or had observations, is invited to post a comment.
The bacterioses in Phalaenopsis, has the most causal agent cited in literature (at least so that I could find) the bacteria Pectobacterium carotovora, whose most common symptoms of infection are soft rot in leaves (pectolytic enzymes released by Pectobacterium carotovora in the internal tissue of the plant, mesophyll, pectates of Ca degrade the middle lamella which is the “cement” that unites in plants one cell to another) and soft rot in pseudobulbos, that rot is also called anasarca (ponding regions and bad smell). In addition to this agent, cited were other bacteria with the potential to cause disease in orchids in general, such as Pseudomonas sp., Erwinia carotovora, Erwinia chrysanthemi and Acidovorax avenae pathovar cattleyae, but to properly identify it is necessary biochemical tests more complex.
