Host-parasite models on graphs [PDF]

open access: yesPhysical Review E, 2005
The behavior of two interacting populations, ``hosts''and ``parasites'', is investigated on Cayley trees and scale-free networks. In the former case analytical and numerical arguments elucidate a phase diagram, whose most interesting feature is the absence of a tri-critical point as a function of the two independent spreading parameters. For scale-free

Confirmation of Galba truncatula as an intermediate host snail for Calicophoron daubneyi in Great Britain, with evidence of alternative snail species hosting Fasciola hepatica

open access: yesParasites & Vectors, 2015
Background Fasciola hepatica is a highly prevalent parasite infecting livestock in Great Britain, while Calicophoron daubneyi is an emerging parasite within the GB livestock industry. Both F. hepatica and C. daubneyi require an intermediate host snail to

The Influence of Parasite Infections on Host Immunity to Co-infection With Other Pathogens

open access: yesFrontiers in Immunology, 2018
Parasites have evolved a wide range of mechanisms that they use to evade or manipulate the host's immune response and establish infection. The majority of the in vivo studies that have investigated these host-parasite interactions have been undertaken in

Discovery of Early-Branching Wolbachia Reveals Functional Enrichment on Horizontally Transferred Genes

open access: yesFrontiers in Microbiology, 2022
Wolbachia is a widespread endosymbiont of insects and filarial nematodes that profoundly influences host biology. Wolbachia has also been reported in rhizosphere hosts, where its diversity and function remain poorly characterized.

Bovine cryptosporidiosis: impact, host-parasite interaction and control strategies

open access: yesVeterinary Research, 2017
Gastrointestinal disease caused by the apicomplexan parasite Cryptosporidium parvum is one of the most important diseases of young ruminant livestock, particularly neonatal calves.

Coevolution of hosts and parasites

open access: yesParasitology, 1982
The coevolution of parasites and their hosts has both general biological interest and practical implications in agricultural, veterinary and medical fields. Surprisingly, most medical, parasitological and ecological texts dismiss the subject with unsupported statements to the effect that ‘successful’ parasite species evolve to be harmless to their ...

Toxoplasma gondii seroprevalence in extensively farmed wild boars (Sus scrofa) in Denmark

open access: yesActa Veterinaria Scandinavica, 2019
Toxoplasma gondii is a zoonotic parasite of worldwide importance. In this study, we estimated T. gondii seroprevalence in extensively farmed wild boars in Denmark, where little is known about T. gondii in animal hosts.

Detecting parasite associations within multi-species host and parasite communities

open access: yesProceedings of the Royal Society B, 2019
Understanding the role of biotic interactions in shaping natural communities is a long-standing challenge in ecology. It is particularly pertinent to parasite communities sharing the same host communities and individuals, as the interactions among ...

Vector-borne parasites in dogs from Ukraine translocated to Poland following Russian invasion in 2022

open access: yesParasites & Vectors, 2023
Introduction Since 24 February 2022, the day the Russian aggression against Ukraine began, millions of refugees and thousands of pets crossed the Polish-Ukrainian border. Additionally, an unknown number of shelter and stray dogs and cats were rescued and

Biogeographical patterns of endolithic infestation in an invasive and an indigenous intertidal marine ecosystem engineer [PDF]

open access: yes, 2019
By altering the phenotypic properties of their hosts, endolithic parasites can modulate the engineering processes of marine ecosystem engineers. Here, we assessed the biogeographical patterns of species assemblages, prevalence and impact of endolithic ...
