Pectobacterium sp. isolated from the soft rot of the columnar cactus Neobuxbaumia tetetzo. Pectobacterium

Neobuxbaumia tetetzo is a columnar cactus endemic to Mexico, commonly known as tetecho. In young and adult plants of N. tetetzo, the presence of damages has been observed, ranging from chlorotic spots with a wet appearance in early stages to tissue necrosis in advanced stages and finally the death of the plant; damages are caused by the bacteria Pectobacterium brasiliense. Disease progression may be delayed or accelerated by the involvement of other bacteria, either pathogenic or endophytic, at the site of infection. Our goal was to confirm the presence of the species Pectobacterium brasiliense, in the soft rot of N. tetetzo and to determine the presence of other bacteria associated with rot.
