What makes a host profitable? Parasites balance host nutritive resources against immunity [PDF]

, 2008
Numerous host qualities can modulate parasite fitness, and among these, host nutritive resources and immunity are of prime importance. Indeed, parasite fitness increases with the amount of nutritive resources extracted from the host body and decreases ...

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.

Genome-wide diversity and gene expression profiling of Babesia microti isolates identify polymorphic genes that mediate host-pathogen interactions [PDF]

, 2016
Babesia microti, a tick-transmitted, intraerythrocytic protozoan parasite circulating mainly among small mammals, is the primary cause of human babesiosis.

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.

Resolving the infection process reveals striking differences in the contribution of environment, genetics and phylogeny to host-parasite interactions [PDF]

, 2011
Background Infection processes consist of a sequence of steps, each critical for the interaction between host and parasite. Studies of host-parasite interactions rarely take into account the fact that different steps might be influenced by different ...

Targeted Knockout of the Rickettsia rickettsii OmpA Surface Antigen Does Not Diminish Virulence in a Mammalian Model System

mBio, 2015
Strains of Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever (RMSF), differ dramatically in virulence despite >99% genetic homology.

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.

Host-parasite fluctuating selection in the absence of specificity [PDF]

, 2017
Fluctuating selection driven by coevolution between hosts and parasites is important for the generation of host and parasite diversity across space and time. Theory has focused primarily on infection genetics, with highly specific ‘matching allele’

Calcium Builds Strong Host-Parasite Interactions [PDF]

Cell Host & Microbe, 2015
Apicomplexan parasite invasion of host cells is a multistep process, requiring coordinated events. In this issue of Cell Host & Microbe, Paul et al. (2015) and Philip and Waters (2015) leverage experimental genetics to show that the calcium-regulated protein phosphatase, calcinuerin, regulates invasion in multiple parasite species.

Discovery of RUF6 ncRNA–interacting proteins involved in P. falciparum immune evasion

Life Science Alliance, 2023
An RNA-directed proteomic discovery (ChIRP-MS) protocol is used to identify in vivo RUF6 ncRNA–protein interactions that sustain virulence genes in the human malaria parasite, Plasmodium falciparum .
