Isothermal diagnostic assays for the detection of soil-transmitted helminths based on the SmartAmp2 method

open access: yesParasites & Vectors, 2017
Background Diagnosis of soil-transmitted helminths (STHs) has traditionally relied on stool microscopy, which has a number of critical deficiencies. Molecular diagnostics are powerful tools to identify closely related species, but the requirement for ...

HIF-1α hampers dendritic cell function and Th1 generation during chronic visceral leishmaniasis

open access: yesScientific Reports, 2018
Inflammation, although responsible for controlling infection, is often associated with the pathogenesis of chronic diseases. Leishmania donovani, the causative agent of visceral leishmaniasis, induces a strong inflammatory response that leads to ...

Exploring the virulence gene interactome with CRISPR/dCas9 in the human malaria parasite

open access: yesMolecular Systems Biology, 2020
Mutually exclusive expression of the var multigene family is key to immune evasion and pathogenesis in Plasmodium falciparum, but few factors have been shown to play a direct role.

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

open access: yesOpen 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 ...

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 ...

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.

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.

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.

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

open access: yesInternational 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.
