Microsporidia – Emergent Pathogens in the Global Food Chain
Trends in Parasitology
Reason for embargo
Intensification of food production has the potential to drive increased disease prevalence in food plants and animals. Microsporidia are diversely distributed, opportunistic, and density-dependent parasites infecting hosts from almost all known animal taxa. They are frequent in highly managed aquatic and terrestrial hosts, many of which are vulnerable to epizootics, and all of which are crucial for the stability of the animal–human food chain. Mass rearing and changes in global climate may exacerbate disease and more efficient transmission of parasites in stressed or immune-deficient hosts. Further, human microsporidiosis appears to be adventitious and primarily associated with an increasing community of immune-deficient individuals. Taken together, strong evidence exists for an increasing prevalence of microsporidiosis in animals and humans, and for sharing of pathogens across hosts and biomes.
This review is an output from a symposium sponsored by the Organisation for Economic Cooperation and Development (OECD) Cooperative Research Programme (CRP) on Biological Resource Management for Sustainable Agricultural Systems and the Society for Invertebrate Pathology (SIP), held on 9th August 2015 at the University of British Columbia, Vancouver, BC, Canada. The symposium was entitled ‘Microsporidia in the Animal to Human Food Chain: An International Symposium To Address Chronic Epizootic Disease’. We acknowledge the generous funding provided by the OECD CRP and the SIP to speakers at this event. The lead author (G.D.S.) would like to acknowledge funding by DG SANCO of the European Commission (under contract C5473) and the UK Department for Environment, Food, and Rural Affairs (DEFRA) (under contract FB002).
