A very early step in microbial colonization and pathogenesis is that involving recog nition of the host by the microbe. In the final analysis such recognition is due to interaction between specific molecules on the two sides, without which host and microbe would ignore each other. It is therefore exciting to learn the rules that govern host-microbe interaction at to a large extent determines whether or not we are infected by the molecular level, which influenza virus, leishmanias, staphylococci and other pathogens. This book is a compendium of the addresses delivered at a symposium on molecular interaction at Porvoo, Finland in August 1991. Realizing that there are no a priori differ ences in receptor recognition in viruses, eukaryotic parasites and bacteria, we freely inter mingled these microbes at the symposium, and in this book. We found the interdisciplinary discussions and comparisons both educative and stimulating. Thus the book is divided into parts that focus on host cell receptors, on microbial recognition molecules and molecules that mediate microbial interaction with a host cell receptor and, briefly, on the molecular events that follow. Although many microbes and many cellular receptors are missing from the book -owing to the limited duration and size of the symposium -the articles presented here constitute an impressive body of examples of how initial host-microbe interaction can come about. We believe that as such the book is a useful and interesting overview of the mechanisms and principles involved in these interactions.

Multiple demographic or economic parameters contribute to the origin of emerging infections, for example: poverty, urbanization, climate change, conflicts and population migrations. All these factors are a challenge to assess the impact (present and future) of parasitic diseases on public health. The intestine is a major target of these infections; it is a nutrient-rich environment harbouring a complex and dynamic population of 100 trillion microbes: the microbiome. Most researches on the microbiome focus on bacteria, which share the gut ecosystem with a population of uni- and multi cellular eukaryotic organisms that may prey on them. Our interest focuses on the families of eukaryotic microbes inhabiting the intestine, called “intestinal eukaryome”, that include fungi, protists and helminths. Knowledge on the reciprocal influence between the microbiome and the eukaryome, and on their combined impact on homeostasis and intestinal diseases is scanty and can be considered as an important emerging field. Furthermore, the factors that differentiate pathogenic eukaryotes from commensals are still unknown. This book presents an overview of the science presented and discussed in the First Eukaryome Congress held from October 16th to 18th, 2019 at the Pasteur Institute in Paris. This book covers the following topics: Phylogenetic, prevalence, and diversity of intestinal eukaryotic microbes; and their (still enigmatic) historical evolution and potential contributions to mucosal immune homeostasis. Integrative biology to study the molecular cell biology of parasite-host interactions and the multiple parameters underlining the infectious process. The exploitation of tissue engineering and microfluidics to establish three-dimensional (3D) systems that help to understand homeostasis and pathological processes in the human intestine.

The growing body of information on bacteria pathogenic for humans, mammals and plants generated within the past ten years has shown the interesting conservation of newly identified genes that playa direct role in the pathogenic mechanism. In addition to these genes, there are also genes that confer host specificities and other traits important in pathogenesis on these pathogens. In this volume, we have organized the subject areas to best fit the concept on the way bacterial pathogens recognize, interact and invade the host, on the regulation of genes involved in virulence, on the genes involved in the elaboration of toxins and other pathogenic components such as iron sequestering proteins, and on the mechanisms of circumventing the host defense systems. These areas are divided into Sections. Section I covers the first step when the pathogen seeks its host, and Sections II through VI cover subsequent steps leading to pathogenesis while avoiding host defenses. We conclude this work with a chapter summarizing information on examples of virulence mechanisms that are highly conserved.

Tropical diseases such as leishmaniasis, malaria. trypanosomiasis, toxoplasmosis and amebiasis continue to plague the world, resulting in considerable morbidity and mortality, especially in the third world countries. These diseases are caused by a group of protozoa which have, over the years, undergone evolutionary adaptation to live often intracellularly in a parasitic way of life. So well-adapted have they become that they recognize the right hosts or cells to parasitize, yet at the same time they escape recognition and destruction by the host immune system. The mechanisms of such recognition and the escape of recognition are governed largely by host-parasite surface membrane interactions at the cellular and molecular level. Unique molecules produced by unusual pathways of these parasites have also been discovered and found to play important roles in their survival in the host. Understanding these mechanisms and pathways is essential not only to formulate a rational strategy for chemo- and immuno-prophylaxis and -therapy but also to unravel the mystery of biological evolution in symbiosis and parasitism. In the advent of our knowledge on the molecular biology and biochemistry of parasite membrane and other molecules, it is opportune to examine and discuss their possible roles in host-parasite recognition and interaction in a comparative approach. To highlight the recent advances of this area in various host-parasite systems, a NATO advanced Research Workshop was held from September 27 to October 1, 1986 at Hotel Villa del Mare, Acquafredda di Maratea, Italy.

Immune Recognition and Evasion: Molecular Aspects of Host-Parasite Interaction reviews recent advances in understanding the genetic basis of host-parasite interactions, with emphasis on antigenic epitopes, the genetics of parasites, the molecular mechanisms of immune recognition and evasion, and the way that cytokines and hormones act on host-parasite interactions. Organized into four parts encompassing 25 chapters, this volume begins with an overview of the genomic organization of the T cell receptor genes and the contribution of non-B DNA structures to switch recombination in immunoglobulin genes. It then discusses signal transduction by class II molecules encoded by the major histocompatibility complex la and the biological consequences of this process; allelic polymorphism of HLA class II antigens and its connection to the molecular basis of autoimmunity; mimicry between HLAB27 and bacteria; and genetic control of susceptibility to helminth infection. The reader is also introduced to recognition of protein antigens by antibodies; recognition of influenza antigens by class I-restricted cytotoxic T lymphocytes; the biochemical basis of cachexia of infection; mechanisms of antigenic variation in Plasmodium; and rational design of trypanocidal drugs. Geneticists and molecular biologists will gain valuable information from this book.

Research on the interactions of plants and phytopathogenic fungi has become one of the most interesting and rapidly moving fields in the plant sciences, the findings of which have contributed tremendously to the development of new strategies of plant protection. This book offers insight into the state of present knowledge. Special emphasis is placed on recognition phenomena between plants and fungi, parasitization strategies employed by the phytopathogenic fungi, the action of phytotoxins, the compatibility of pathogens with host plants and the basic resistance of non-host plants as well as cultivar-specific resistance of host plants. Special attention is paid to the gene-for-gene hypothesis for the determination of race-specific resistance, its molecular models and to the nature of race non-specific resistance as well as the population dynamics of plants and the evolution of their basic resistance.
