Host sexual dimorphism and parasite adaptation [PDF]

, 2012
In species with separate sexes, parasite prevalence and disease expression is often different between males and females. This effect has mainly been attributed to sex differences in host traits, such as immune response.

Chromatin structure can introduce systematic biases in genome-wide analyses of Plasmodium falciparum [version 2; peer review: 2 approved]

Open Research Europe, 2022
Background: The maintenance, regulation, and dynamics of heterochromatin in the human malaria parasite, Plasmodium falciparum, has drawn increasing attention due to its regulatory role in mutually exclusive virulence gene expression and the silencing of ...

Extracellular Vesicle-Mediated Communication Within Host-Parasite Interactions

Frontiers in Immunology, 2019
Extracellular vesicles (EVs) are small membrane-surrounded structures released by different kinds of cells (normal, diseased, and transformed cells) in vivo and in vitro that contain large amounts of important substances (such as lipids, proteins ...

Diverse Requirements for Src-Family Tyrosine Kinases Distinguish Chlamydial Species

mBio, 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

International 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 ...

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

Proceedings 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.

Multiple drug resistance in hookworms infecting greyhound dogs in the USA

International 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]

, 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.

The coevolution of virulence : tolerance in perspective [PDF]

, 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.

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

Disease 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.
