A simple isothermal DNA amplification method to screen black flies for Onchocerca volvulus infection. [PDF]

PLoS ONE, 2014
Onchocerciasis is a debilitating neglected tropical disease caused by infection with the filarial parasite Onchocerca volvulus. Adult worms live in subcutaneous tissues and produce large numbers of microfilariae that migrate to the skin and eyes.

Extracellular Onchocerca-derived small RNAs in host nodules and blood

Parasites & Vectors, 2015
Background microRNAs (miRNAs), a class of short, non-coding RNA can be found in a highly stable, cell-free form in mammalian body fluids. Specific miRNAs are secreted by parasitic nematodes in exosomes and have been detected in the serum of murine and ...

Epilepsy in Onchocerca volvulus Sero-Positive Patients From Northern Uganda—Clinical, EEG and Brain Imaging Features

Frontiers in Neurology, 2021
Globally, epilepsy is the most common chronic neurological disorder. The incidence in sub-Saharan Africa is 2-3 times higher than that in high income countries.

Simuliidae and the transmission and control of human Onchocerciasis in Latin America

Cadernos de Saúde Pública, 1991
Factors that affect the propensity of a simuliid species to act as a host to Onchocerca volvulus and to naturally transmit this filarial worm in nature are discussed.

Advancing a Human Onchocerciasis Vaccine From Antigen Discovery to Efficacy Studies Against Natural Infection of Cattle With Onchocerca ochengi

Frontiers in Cellular and Infection Microbiology, 2022
Human onchocerciasis is a devastating neglected tropical disease caused by infection of the filarial nematode Onchocerca volvulus. The infection can cause irreversible visual impairment or blindness and stigmatizing dermatitis.

The Functional Parasitic Worm Secretome: Mapping the Place of Onchocerca volvulus Excretory Secretory Products

Pathogens, 2020
Nematodes constitute a very successful phylum, especially in terms of parasitism. Inside their mammalian hosts, parasitic nematodes mainly dwell in the digestive tract (geohelminths) or in the vascular system (filariae). One of their main characteristics

Unraveling cross-reactivity of anti-glycan IgG responses in filarial nematode infections

Frontiers in Immunology, 2023
Parasitic nematodes responsible for filarial diseases cause chronic disablement in humans worldwide. Elimination programs have substantially reduced the rate of infection in certain areas, but limitations of current diagnostics for population ...

Evolution of Ivermectin Resistance in the Nematode Model Caenorhabditis elegans: Critical Influence of Population Size and Altered Emodepside Efficacy

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT The emergence and spread of anthelmintic resistance represent a major challenge for treating parasitic nematodes, threatening mass‐drug administration control programs in humans and zoonotic hosts. Currently, experimental evidence to understand the influence of management (e.g., treatment dose and frequency) and parasite‐associated factors (e ...

Helminths as architects of trained tolerance: implications for human health

Clinical &Translational Immunology, Volume 15, Issue 3, 2026.
Abstract Helminths infect nearly 2 billion people worldwide and are a major cause of chronic morbidity in low‐resource regions. Unlike bacterial and viral pathogens that elicit protective memory, helminths actively remodel host immunity to enable their years‐long persistence and reinfection.
