Helminthiases; prevalence, transmission, host-parasite interactions, resistance to common synthetic drugs and treatment

Heliyon, 2019
The morbidity caused by parasite worms on susceptible hosts is of great concern and studies were carried out to explain the mechanism of infection, prevalence, host-parasite interaction and resistance of the parasite to treatment.

Intravital imaging of host–parasite interactions in skin and adipose tissues

Cellular Microbiology, 2019
Intravital microscopy allows the visualisation of how pathogens interact with host cells and tissues in living animals in real time. This method has enabled key advances in our understanding of host–parasite interactions under physiological conditions. A

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.

Using host species traits to understand the consequences of resource provisioning for host–parasite interactions

Journal of Animal Ecology, 2017
Supplemental food provided to wildlife by human activities can be more abundant and predictable than natural resources, and subsequent changes in wildlife ecology can have profound impacts on host–parasite interactions.

Life-history responses, transmission dynamics and epidemiology in a terrestrial gastropod infected with parasitic mites [PDF]

, 2010
Parasites are known to influence the life-history of their hosts. A parasite-induced reduction in host fecundity and survival may lead to a reduced rate of increase in the host population.

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.

Lipid Droplet, a Key Player in Host-Parasite Interactions

Frontiers in Immunology, 2018
Lipid droplets (lipid bodies, LDs) are dynamic organelles that have important roles in regulating lipid metabolism, energy homeostasis, cell signaling, membrane trafficking, and inflammation. LD biogenesis, composition, and functions are highly regulated

Metazoan-protozoan parasite co-infections and host body weight in St Kilda Soay sheep [PDF]

, 2008
For hundreds of years, the unmanaged Soay sheep population on St Kilda has survived despite enduring presumably deleterious co-infections of helminth, protozoan and arthropod parasites and intermittent periods of starvation.

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 .
