Bacterial Wetwood
Large elm and poplar trees with vertical stripes of bleached bark are a common sight in many parts of the U.S. The disease, bacterial wetwood, and the slime flux associated with it cause the bark discoloration. Bacterial wetwood can be found throughout the entire continental U.S. but symptoms are variable in susceptible trees of the western part of the country. The most common causal organisms associated with the disease are Enterobacter cloacae (Jordan Hormaeche and Edwards (= Erwinia nimipressuralis Cart.), Bacillus magaterium DeBary and Pseudomonas fluorescens Migula.
