Host–parasite interactions

2006
DISTRIBUTION OF ACANTHOCEPHALANS WITHIN HOSTS Distribution in individual hosts Although adult acanthocephalans are found in the alimentary tract of their vertebrate definitive hosts, they do, in common with other groups of intestinal parasites, exhibit preferences for particular regions of that tract. Crompton (1973) has reviewed the sites occupied

Manipulation of apoptosis in the host–parasite interaction

Trends in Parasitology, 2004
Abstract Nearly all animal cells possess the capacity to undergo programmed cell death (apoptosis) when stimulated by an appropriate trigger. Apoptosis is crucial for maintaining social order among the cells comprising metazoans, but it also has other functions: the existence of apoptosis in single-celled organisms implies a degree of interaction ...

Genetics of Host-Parasite Interactions

1976
Most plant pathogens, whether obligate parasites (biotrophs) or facultative saprophytes (necrotrophic pathogens) have a host range limited to few species. For host and parasite to survive and evolve together it is necessary for equilibrium, either dynamic or stable, to be established between them, such that each is capable of adequate reproduction ...

Host–parasite interactions in polluted environments

Journal of Fish Biology, 2008
In recent years, there has been an increasing number of papers showing how parasitism and pollution can interact with each other in aquatic organisms. In addition to synergistic negative effects of both stressors, there are also indications of antagonistic interactions.

Host-parasite interaction in fungal infections

European Journal of Clinical Microbiology & Infectious Diseases, 1989
The outcome of host-parasite interactions in fungal infections is determined by the balance between pathogenicity of the organism and the adequacy of the host defenses. A wide variety of host defense mechanisms are involved in protection against fungal infections.

The genetics of host-parasite interaction

1993
Plant parasites are sometimes divided into two classes on the basis of the ways in which they derive nutrients from their hosts (Pryor, 1987). Biotrophs obtain their nutrients from living cells, often through specialized feeding structures termed haustoria. In contrast, necrotrophs kill their hosts’ cells and feed on the dead remains. Biotrophs tend to

Host-Parasite Interactions in Leishmaniasis

1992
Publisher Summary This chapter discusses the host–parasite interactions in leishmaniasis. Parasites have evolved many specific adaptations that enable them to interact with the host. Leishmania are obligatory intracellular parasites in a very narrow range of cells, and therefore, have great specificity for their host cell, the macrophage.

Genetics of Host-Parasite Interaction

1986
The host and the parasite are the two biological entities involved in the host-parasite interrelationship. The studies on the genetics of resistance in the host and pathogenicity in the pathogen are important to understand the basic aspects of the interrelationships of host and parasite.

The Genetics of Host–Parasite Interaction

2014
Studies on the genetics of host-parasite interactions in white rust (WR) diseases have focused on the level of specificity among races of pathogen and genotypes of related host species. Even within the confines of race-cultivar specificity, the studies have been one-side in that no genetic information has been generated on Albugo, the causal organism ...

Specificity in Host-Parasite Interaction

1976
Two extraordinary things about animal parasites are their capacity to live in intimate contact with tissues of totally different genetic origin, and their ability to move from host to host with an apparent blithe disregard for phylogenetic differences and accepted tenets of cell biology and immunology.
