Introductory Comments on Host-Parasite Interactions

  • R. K. S. Wood
Part of the NATO ASI Series book series (volume 1)


Although this Workshop is about the biology as well as the molecular biology of host/parasite relations I think that my comments would be spread too thinly were they on both. Therefore, and because of what I expect to be the preoccupation of the Workshop, I shall confine them very largely to interactions at cellular and sub-cellular levels. Even thus the scope and the substance are so huge that the survey I shall attempt must be somewhat superficial and is likely to achieve not much more than remind you of what is already known. I am afraid too that I ask all too many questions for which no-one has the answer. But this reflects the complexity of and our ignorance about the phenomena to be discussed. I shall start with the interactions about which most is known, between races and cultivars and continue but much more briefly with interactions at other levels.
