This edited volume focuses on parasite-host relationships and the behavioral changes parasites may trigger in their hosts. Parasites have developed strategies which enhance their chances to find a host to survive inside its body and to become most easily transmitted to one another. Many of these parasites influence the host’s behavior by various mechanisms, so that the rate of their transmissions to further hosts becomes considerably enhanced in comparison to that of non-influenced specimens of the same host species. A broad number of recent studies elucidate more and more examples in an extreme spectrum of host-parasite relationships, where successful transmission and /or survival of a parasite inside a host is based on parasite-derived behavioral manipulations of the hosts. In the literature, an increasing numbers of papers appear which prove that these behavioral alterations are based on complicated psychoimmunologic, neuropharmacologic and genomically steered mechanisms. Researchers working in parasitology or behavioral sciences will find this work thought-provoking, instructive and informative.

Defending Life discusses the relationship between hosts and parasites. It contains detailed descriptions of the immune system and the microbial world as well as methodological and conceptual clarifications. Its emphasis on analytical abstractions, coherent patterns and generative mechanisms makes possible the distinction between genuine causality and coincidental associations and increases the understanding of why we observe what we observe.

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.

Biogeography has renewed its concepts and methods following important recent advances in phylogenetics, macroecology, and geographic information systems. In parallel, the evolutionary ecology of host-parasite interactions has attracted the interests of numerous studies dealing with life-history traits evolution, community ecology, and evolutionary epidemiology. The Biogeography of Host-Parasite Interactions is the first book to integrate these two fields, using examples from a variety of host-parasite associations in various regions, and across both ecological and evolutionary timescales. Besides a strong theoretical component, there is a bias towards applications, specifically in the fields of historical biogeography, palaeontology, phylogeography, landscape epidemiology, invasion biology, conservation biology, human evolution, and health ecology. A particular emphasis concerns emerging and re-emerging infectious diseases linked to global changes.

This is a question-oriented volume with a solid organismal foundation that will help to bridge the gap between evolutionary ecologists and parasitologists. A range of experts have written chapters that review general concepts and provide a detailed survey of the parasites of a major group of hosts. The book concludes with extensive reviews of methods used to study bird parasites. It is a novel and valuable tool for anyone interested in understanding host-parasite interactions, particularly from an evolutionary perspective.

The host and the parasite are the two different biological organisms involved in host parasite interactions. The parasite or pathogen is a benefited organism which is dependent on the host for its existence. The host and the parasite live in close proximity and the latter enjoys at the expense of the first. The parasite is like an intruder for the host which it wants to eliminate by various responsive reactions and resistance. In response, parasite generates several features such as polyembryony, production of special enzymes, increased fecundity, self-habitat, etc. This close association is referred to as host parasite interactions. Different types of parasites have been recognized on different basis. In terms of host specificity, parasites may be mono-specific or poly-specific. Mono-specific parasite restricts to a single host whereas poly-specific might associate with different genetically related hosts. Eventually, a mutual relation between the host and the parasite develops which allows them to survive together. The fatal parasites, however, try to kill the hosts. But killing the hosts will lead to the death of parasites itself. Host characteristics might be affected by intimate association with the parasite. These may include damage of tissue, necrosis, hyperplasia, neoplasia, malnourishment, etc. There are several parasitic plants and fungi which attack the plants. Parasitic plant extracts its resources from the vascular system of another living plant (host) using a specialized transfer organ called haustorium. Some examples of parasitic plants include Mistletoes, Yellow Rattle (Rhinanthus), Red Bartsia (Odontites) and Eyebrights (Euphrasia). These are hemi-parasitic members and have their own green leaves. Plants like Toothworts (Lathraea) and Broomrapes (Orobanche) are the examples of holo-parasitic plants which have no photosynthetic green leaves of their own. The Dodders (Cuscuta) are another common group of parasites. This book discusses the plant host parasite relationship and is a gathering of few research papers on interactions of parasitic plants/fungi with the host plants. The first three chapters throw light on the overview of host parasite interactions in plants. Chapter 4 describes the genetic transfer facilitation among plants by the association between the host and the parasite. The next chapter focuses on the interaction of Cuscuta reflexa with tomato plant. The molecular events during the parasitic plant host interaction are described in chapter 6. The next chapter covers the applicability of Limiting Resource Model (LRM) for understanding the effects of drought on tolerance to holoparasite Cuscuta gronovii. Chapter 8 discusses the compatibility or incompatibility of hosts by screening the response of four plant species of Solanaceae family to the parasitism of Cuscuta campestris Yuncker. Horizontal gene transfer between the host and the parasite nuclear genomes; and the consequences of Orobanche crenata infection severity in different legume crops viz. faba bean, field pea and grass pea have been discussed in chapters 9 and 10, respectively. Chapter 11 evaluates the effect of amino acids as herbicides for field control of Orobanche minor parasitism in red clover. The relationships of the parasitic plant Phelipanche ramosa (L.) and different hosts; and the microbiome of the parasitic weed Phelipanche aegyptiaca and tomato is described in the following two chapters, respectively. The last chapter discusses how water influences the effects of stem hemiparasites on hosts.
