  • From a series of controlled infection experiments that manipulate competition among the parasites we can show that, although both species occur in the same section of the mussel gut, competition between the parasites is weak and shows similar impact on host condition in either simultaneous or sequential infections. (awi.de)
  • We find that they lessen the negative effects of infection on hosts and reduce infectivity by directly competing with parasites. (ox.ac.uk)
  • In vivo infection routes of parasites have remained something of a 'black box', in which only snapshot views of fixed tissues are available. (epfl.ch)
  • Thus, even though the unique eukaryotic biology of Leishmania and its dependence on parasite-specific virulence factors provide valid opportunities for chemotherapeutical intervention, all strategies that target the parasite in a direct fashion are likely prone to select for resistance.

  • RESULTS: Using a phenotypic framework, we explore the evolutionary and coevolutionary dynamics of a host-parasite interaction in the presence of defensive microbes. (ox.ac.uk)
  • CONCLUSIONS: Defensive microbes might thus play a central role in host-parasite interactions, by outright replacing host-based defences, engaging in within-host competition with parasites, and ultimately driving tripartite coevolutionary dynamics. (ox.ac.uk)
  • This text is not simply an updated version of typical parastitology books but takes an integrated approach and explains how the study of parasites requires an understanding of a wide range of other topics from molecular biology and immunology to the interactions of parasites with both their hosts and other pathogens. (abebooks.com)
  • The effects of parasitic infections are influenced by a range of host factors such as genetic constitution, immune status, and behaviour and this text takes an integrated approach to provide a full understanding of a wide range of topics from molecular biology and immunology to social, religious and cultural factors.

  • The relative abundance for these two species has changed both locally and regionally over this time period with a reduction in host abundance coincident with an increase in the parasite population. (usda.gov)
  • Within parasite communities infecting the same host, ecological theory predicts that two species occupying the same niche should evolve distinct niche use to avoid direct competition. (awi.de)
  • Biological invasions can however create situations, where competition could not select for different niche occupancy and closely related parasites species find themselves competing for the same host resources for the first time since their lineages split. (awi.de)
  • Such novel interactions cannot only alter the evolutionary trajectories of both parasite species, but will also feed back on the immune response of the host. (awi.de)
  • New research approaches have highlighted host as well as parasite molecules or pathways that could be targeted for interventions. (nih.gov)
  • The role of certain hormones in parasitic infections has been demonstrated, and there are documented direct effects of hormones on parasites. (omicsonline.org)
  • The book focuses strongly on parasite interactions with other pathogens and in particular parasite-HIV interactions, as well as looking at how host behaviour contributes to the spread of infections. (abebooks.com)
  • There is a consideration of the positive aspects of parasite infections, how humans have used parasites for their own advantage and also how parasite infections affect the welfare of captive and domestic animals. (abebooks.com)
  • The aim of the research is to understand the molecular and cellular immunological basis of host parasite interaction with particular emphasis on chronic helminth infections and more recently malaria. (lumc.nl)
  • We finally propose new strategies that target Leishmania viability indirectly via mechanisms of host-parasite interaction, including parasite-released ectokinases and host epigenetic regulation, which modulate host cell signaling and transcriptional regulation, respectively, to establish permissive conditions for intracellular Leishmania survival. (archives-ouvertes.fr)
  • Here, we used data from a 40‐yr demographic study on breeding Wood Thrushes ( Hylocichla mustelina ) and avian brood parasitic Brown‐headed Cowbirds ( Molothrus ater ) in the mid‐Atlantic United States to disentangle host-parasite interactions. (usda.gov)
  • Here, we show how the invasion of the parasitic copepod Mytilicola orientalis creates competition with the established congeneric parasite Mytilicola intestinalis, and how this novel menage a trois feeds back on the immune response of the blue mussel host Mytilus edulis. (awi.de)

  • Thus, understanding the mechanisms involved in immunoendocrine modulation and its effects on parasites is essential for developing new drugs, finding vaccine targets and devising new therapies for several infectious diseases. (omicsonline.org)
  • Triplet transcriptomics of matching host (M. edulis) and parasite samples (M. intestinalis and M. orientalis) however revealed that the novel interaction of the invader with the host changes the transcriptional activity of many more genes and processes than the interaction with the established and coevolved parasite.

  • Our results therefore not only show the utility of biological invasions of parasites to study coevolutionary processes, but also shows that responses to novel host-parasite interactions can lead to massive reactions on the molecular level that are not reflected in host or parasite phenotypes. (awi.de)
  • Conversely, parasites themselves are phylogenetically diverse, target a range of different tissues, and have evolved numerous alternative strategies to evade or inhibit protective immune responses by strategies, such as antigenic variation, molecular mimicry or affecting antigen processing and presentation.
