Abstract

The United States Department of Agriculture currently lists fewer than a dozen plant-associated microbial species as select agents. This list is a by-product of the Agricultural Bioterrorism Protection Act, which is part of the larger Public Health Security and Bioterrorism Preparedness Response Act of 2002. Although there is discussion within the academic community about the relative risk of taxa in that list [1], work within the United States on any of these taxa is highly regulated, even if the organism is already established in specific regions where research is being conducted and immediately needed to reduce pathogen spread. Among the taxa in this list is the citrus variegated chlorosis (CVC) strain of the plant pathogenic bacterium Xylella fastidiosa. Although we will focus this chapter on the phylogenetic group of X. fastidiosa causing CVC (subsp. pauca), general aspects of X. fastidiosa classification, detection, and biology require background that includes other subspecies, which are included here as necessary.
