Host specificity and genetics of host resistance in the "Daphnia-Pasteuria" host-parasite system [PDF]

open access: yes, 2012
Antagonistic coevolution plays an important role in a large number of evolutionary and ecological phenomena. Furthermore, according to the Red Queen Theory coevolution between hosts and their parasites may explain the maintenance of sexual reproduction ...

Diverse Requirements for Src-Family Tyrosine Kinases Distinguish Chlamydial Species

open access: yesmBio, 2011
Chlamydiae are well known for their species specificity and tissue tropism, and yet the individual species and strains show remarkable genomic synteny and share an intracellular developmental cycle unique in the microbial world.

The use of ITS-2 rDNA nemabiome metabarcoding to enhance anthelmintic resistance diagnosis and surveillance of ovine gastrointestinal nematodes

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance, 2020
(300 words): A lack of quantitative information on the species composition of parasite communities present in fecal samples is a major limiting factor for the sensitivity, accuracy and interpretation of the diagnostic tests commonly used to assess ...

Multiple drug resistance in hookworms infecting greyhound dogs in the USA

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance, 2021
Ancylostoma caninum is the most prevalent nematode parasite of dogs. We confirmed multiple-drug resistance (MDR) in several A. caninum isolates to all anthelmintic drug classes approved for the treatment of hookworms in dogs in the USA.

Within-Host Dynamics of Multi-Species Infections:Facilitation, Competition and Virulence [PDF]

open access: yes, 2012
Host individuals are often infected with more than one parasite species (parasites defined broadly, to include viruses and bacteria). Yet, research in infection biology is dominated by studies on single-parasite infections.

Pathological and ecological host consequences of infection by an introduced fish parasite [PDF]

open access: yes, 2011
The infection consequences of the introduced cestode fish parasite Bothriocephalus acheilognathi were studied in a cohort of wild, young-of-the-year common carp Cyprinus carpio that lacked co-evolution with the parasite.

Targeted repression of Plasmodium apicortin by host microRNA impairs malaria parasite growth and invasion

open access: yesDisease Models & Mechanisms, 2020
Mature human erythrocytes contain a rich pool of microRNAs (miRNAs), which result from differentiation of the erythrocytes during the course of haematopoiesis.

The coevolution of virulence : tolerance in perspective [PDF]

open access: yes, 2010
Coevolutionary interactions, such as those between host and parasite, predator and prey, or plant and pollinator, evolve subject to the genes of both interactors.

Host–parasite interactions and the evolution of ploidy [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
Although the majority of animals and plants, including humans, are dominated by the diploid phase of their life cycle, extensive diversity in ploidy level exists among eukaryotes, with some groups being primarily haploid whereas others alternate between haploid and diploid phases.

Heterogeneous host susceptibility enhances prevalence of mixed-genotype micro-parasite infections [PDF]

open access: yes, 2011
Dose response in micro-parasite infections is usually shallower than predicted by the independent action model, which assumes that each infectious unit has a probability of infection that is independent of the presence of other infectious units. Moreover,
