Serratia marcescens Bizio 1823

The bacterium is characterized by its red colour and causes cucurbit yellow vine disease in North and South America. Affected crops include pumpkin, squash, melon, cotton and watermelon. Infections result in a brown discoloration of the phloem, yellowing and wilting of the leaves as well as final plant collapse.
