Parasite Immunology, 2007
SUMMARY The physiological interactions during the course of any immune response are complex. Infection induces antigen‐specific recognition by the immune system, which is consequently charged with the responsibility of marshalling the appropriate effector responses necessary to destroy the pathogen, or at the very least inhibit its progression ...

Host-parasite dynamics and the evolution of host immunity and parasite fecundity strategies
Bulletin of Mathematical Biology, 1997We explore evolutionarily stable co-evolution of host-macroparasite++ interactions in a discrete-time two-species population dynamics model, in which the dynamics may be stable, cyclic or chaotic. The macroparasites are assumed to harm host individuals through decreased reproductive output. Hosts may develop costly immune responses to defend themselves

Parasites and Their Social Hosts
Trends in Parasitology, 2017The study of parasitism in socially living organisms shows that social group size correlates with the risk of infection, but group structure - and thus differences in contact networks - is generally more important. Also, genetic makeup or environmental conditions have effects.

Journal of Helminthology, 2006
AbstractOver the past decades, various free-living animals (hosts) and their parasites have invaded recipient areas in which they had not previously occurred, thus gaining the status of aliens or exotics. In general this happened to a low extent for hundreds of years.

The Evolution of Host‐Parasite Range
The American Naturalist, 2010Understanding the coevolution of hosts and parasites is one of the key challenges for evolutionary biology. In particular, it is important to understand the processes that generate and maintain variation. Here, we examine a coevolutionary model of hosts and parasites where infection does not depend on absolute rates of transmission and defense but is ...

The phenomenon of parasitism occurs amongst all groups of infective agents whether they are viruses, bacteria, fungi, protozoa, helminths or arthropods. The main concern of this book is with the protozoa, helminths and arthropods, parasites that are still of public health importance in economically advanced societies.

The Ixodes (Acari: Ixodidae) of Mexico: parasite-host and host-parasite checklists
Zootaxa, 2007Parasite-host and host-parasite checklists are provided for all species of Ixodes known from Mexico; host and locality data are from specimens housed in the Colección Nacional de Ácaros, Instituto de Biología, Universidad Nacional Autónoma de México, and from literature. Six Ixodes species (I. brunneus, I. conepati, I. dentatus, I.

The Effects of Parasitism on the Host and on the Parasite
Journal of Economic Entomology, 1926The life of a parasite, contrary to general opinion, is not an easy one, it is full of dangers and the parasite is rigorously circumscribed. Parasitism is an achievement and the term degenerate is not aptly applied to this mode of living. Parasites are adapted to this mode of life in two general respects, namely (1) physiologically and (2 ...
