CURRENT RESEARCH AND TEACHING ACTIVITIES

Prof. Van Bruggen carries out fundamental and applied research on ecosystem health in relation to the invasion by plant and human pathogens. A healthy ecosystem is characterized by a dynamically balanced and diverse community of organisms, stability and resilience after disturbances, minimal losses of nutrients and energy, and sporadic outbreaks of pests and diseases. We hypothesize that the extent of oligotrophy, in terms of easily available carbon sources and mineral nutrients, largely determines the health status of an ecosystem. This concept was developed based on research results on the survival and spread of enteric human pathogens (Escherichia coli O157:H7 and Salmonella enterica) from manure to soil, water and plants. A probabilistic risk model was developed for the contamination of a lettuce crop by manure, soil, and water contaminated with E. coli O157:H7. Internalization of Salmonella enterica serovar Typhmurium in tomato leaves, stems and fruits was shown to occur from contaminated water and aerosols. Simulation models were developed for the survival of E. coli O157:H7 and Salmonella Typhimurium in manure, manure-amended soil and water.

Besides research on ecosystem health and transmission routes of enteric pathogens, the integration of various temporal and spatial scales of ecological processes and the dispersal capacity of (re)emergingpathogens in agroecosystems have been recurrent themes in van Bruggen’s research projects. The dynamics of disease progress can be understood better when we take the response time into account for the different developmental stages of the pathogen in relation to the hourly dynamics of environmental conditions rather than average conditions. This was shown for the plant pathogensBremia lactucaeand Phytophthora infestans as well as for the human pathogens E. coli O157:H7 and S. enterica serovar Typhimurium. This research has implications for the effects of climate change on pathogen growth. We recently submitted a paper on a simulation model for the potential effects of climate change on late blight development.

On the applied side, an audit-based certification system for the greenhouse ornamental industry, including a risk model for pathogen spread, has been developed. In addition, the epidemiology and spread of emerging plant pathogens like Candidatus Liberibacter asiaticusand Guignardia citricarpa associated with citrus huanglongbing and black spot, respectively, as well as Raffaelea lauricola causing laurel wilt and Diaporthe vaccinii causing blueberry twig blight, have been studied and simulation and risk modelshave been developed for the spread of these pathogens.

Prof. Van Bruggen has taught a course on plant disease epidemiology and a colloquium series on the use of statistical methods in plant pathology. She is also participating in the discussion group One Health at the Emerging Pathogens Institute.
