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.

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 ...

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.

Benefits of host genetic diversity for resistance to infection depend on parasite diversity [PDF]

, 2010
Host populations with high genetic diversity are predicted to have lower levels of infection prevalence. This theory assumes that host genetic diversity results in variation in susceptibility and that parasites exhibit variation in infectivity. Empirical

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.

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

, 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 ...

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.

Promise and limitations of 18S genetic screening of extracted fecal DNA from wild capuchins

Frontiers in Ecology and Evolution, 2023
Genomic screening of fecal DNA provides insight into diet, parasite infection dynamics, and other aspects of the ecology and pathogens of wild populations.

Integration of ITS-2 rDNA nemabiome metabarcoding with Fecal Egg Count Reduction Testing (FECRT) reveals ivermectin resistance in multiple gastrointestinal nematode species, including hypobiotic Ostertagia ostertagi, in western Canadian beef cattle

International Journal for Parasitology: Drugs and Drug Resistance, 2023
A large-scale Fecal Egg Count Reduction Test (FECRT) was integrated with ITS-2 rDNA nemabiome metabarcoding to investigate anthelmintic resistance in gastrointestinal nematode (GIN) parasites in western Canadian beef cattle.
