Plasmodium relictum infection in Culex quinquefasciatus (Culicidae) decreases diel flight activity but increases peak dusk flight activity

Malaria Journal, 2022
Background Parasites are recognized for their ability to modify host physiology and behaviours in ways that increase parasite fitness. Protozoan parasites of the genus Plasmodium are a group of widespread vector-borne parasites of vertebrates, causing ...

Characterization of the Plasmodium and Haemoproteus parasite community in temperate-tropical birds during spring migration

International Journal for Parasitology: Parasites and Wildlife, 2021
Animal movements, especially avian migration, can be a mechanism for the large-scale dispersal and geographic range expansion of parasites. The host-parasite relationships among birds during migration have yet to be fully explored.

Assessing Risk Thresholds in Controlled Human Infection Models (CHIM)

Bioethics, Volume 40, Issue 5, Page 519-529, June 2026.
ABSTRACT Controlled Human Infection Models (CHIMs) are a type of clinical trial involving deliberately exposing human volunteers to an infectious agent. Compared to studies of natural infection, CHIMs offers distinctive benefits, from the ability to study presymptomatic infection to a direct assessment of the efficacy of vaccines and therapeutics in a ...

An updated checklist of Culicoides Latreille, 1809 biting midges from the highlands of eastern Democratic Republic of the Congo Une liste mise à jour des moucherons piqueurs de Culicoides Latreille, 1809 des hautes terres de l'est de la République démocratique du Congo

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 422-440, June 2026.
The highlands of eastern Democratic Republic of the Congo (DRC) are home to critically endangered eastern gorillas (Gorilla beringei). Climate change could increase the abundance and distribution of Culicoides‐borne diseases. We utilized morphological and molecular techniques to identify Culicoides spp.

Why Plasmodium vivax and Plasmodium falciparum are so different? A tale of two clades and their species diversities

Malaria Journal, 2022
The global malaria burden sometimes obscures that the genus Plasmodium comprises diverse clades with lineages that independently gave origin to the extant human parasites.

The Human Threat From West Nile Virus and Usutu Virus in a Changing Climate

APMIS, Volume 134, Issue 5, May 2026.
ABSTRACT In recent years, the closely related arboviruses West Nile virus (WNV) and Usutu virus (USUV) have spread farther north in Europe. The viruses often co‐circulate and are maintained in a natural cycle between ornithophilic mosquitoes and birds.

Retroviral Infections Affect Survival and Clutch Size of Female Wild Turkeys

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigated the effects of two oncogenic retroviruses, lymphoproliferative disease virus (LPDV) and reticuloendotheliosis virus (REV), on survival and reproduction of wild turkeys in Maine. REV infection reduced female annual survival by nearly half, while LPDV‐infected hens laid fewer eggs, though other reproductive metrics were unaffected.

Galactose‐α‐1,3‐galactose‐presenting bacterial families are associated with resistance to experimental avian malaria infection

Journal of Avian Biology
The gut microbiome can contribute to host health through defense against pathogens. However, links between the host gut microbiome and resistance to infection have been primarily investigated in humans and lab‐bred rodents, so we do not know to what ...

Dynamics of prevalence and diversity of avian malaria infections in wild Culex pipiens mosquitoes: the effects of Wolbachia, filarial nematodes and insecticide resistance

Parasites & Vectors, 2014
Background Identifying the parasites transmitted by a particular vector and the factors that render this vector susceptible to the parasite are key steps to understanding disease transmission.

Modeling species co‐occurrence effects to inform invasive barred owl management and recovery of the northern spotted owl

Ecological Applications, Volume 36, Issue 2, March 2026.
Abstract Robust estimation of wildlife populations represents a cornerstone of wildlife research and provides critical information to guide management, including identifying at‐risk species, setting harvest rates, and evaluating predator and invasive species control programs.
