HOST-PARASITE INTERACTIONS DURING PREGNANCY
Obstetrical & Gynecological Survey, 1978The point that host defense against infectious disease is exceedingly complex scarcely needs further emphasis. We have tried to show that pregnancy is a state which has the potential for altering any of the many facets of host defense, and in some instances presented evidence that pregnancy does alter resistance to infection.

All organisms have evolved defence mechanisms for protection against invasion and establishment by micro-organisms and by metazoan parasites. Although ideally we should include the viruses and bacteria in our current discussion, space precludes such a full consideration.

1986
Host-parasite interactions have been studied by means of formal genetic procedures since the beginning of this century. It soon proved that resistance of a plant is inherited in a rather simple manner. Parasites, however, have been studied to a much lesser extent than the host plants, largely because of the difficulties in cultivating parasitic ...

The Evolution of Host-Parasite Interaction
1983The extent of economic damage to crop plants due to pests and diseases is very large and well documented. Minimizing this loss through the use of pesticides is expensive. The high cost of pesticides and the threat they pose to non-target organisms make breeding for disease resistance a cost-effective and attractive alternative.

Stochastic host-parasite interaction models
Journal of Mathematical Biology, 2000We contribute to the discussion of causes and effects of aggregation (overdispersion) of macroparasite counts, focussing particularly upon the effects of clumped infections and parasite-induced host mortality. The simple nonlinear stochastic model for the evolution of the parasite load of a single host, investigated in Isham (1995), is extended to ...

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, 2004Abstract 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
1976Most 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, 2008In 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.

The Genetics of Host–Parasite Interaction
2014Studies 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 ...
