Given the results of a previous study showing that TA systems are ubiquitous in VRE (Moritz & Hergenrother, 2007), and the current survey showing that TA systems are also highly prevalent and transcribed in MRSA and PA, it appears that these problematic bacterial pathogens would indeed be susceptible to TA-based antibacterial strategies. Specifically, activation of MazEFSa should be considered for MRSA, and activation of RelEPa or HigBAPa appear to be attractive strategies against PA. This work was supported

“Phytophthora ramorum,Phytophthora alni, and Phytophthora kernoviae present significant threats to biosecurity. As zoosporic oomycetes, these plant pathogens may spread through natural waterways and irrigation systems. However, survival of these pathogens in aquatic systems in response to water quality is not well understood. In this study, we investigated their zoospore survival at pH 3–11 in a 10% Hoagland’s solution over a 14-day period. The results showed that all three pathogens were most stable at pH 7, although the populations declined overnight irrespective of pH. Extended survival of these species depended on the tolerance of pH of their germinants. Germinants of P. alni ssp. alni and P.
