Balancing functions of regulatory T cells in mosquito-borne viral infections

open access: yesEmerging Microbes and Infections
Mosquito-borne viral infections are on the rise worldwide and can lead to severe symptoms such as haemorrhage, encephalitis, arthritis or microcephaly.

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

open access: yesIntegrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Sunshine versus gold: The effect of population age on genetic structure of an invasive mosquito

open access: yesEcology and Evolution, 2020
The genetic diversity and structure of invasive species are affected by the time since invasion, but it is not well understood how. We compare likely the oldest populations of Aedes aegypti in continental North America with some of the newest to ...

Effects of inbreeding and genetic modification on Aedes aegypti larval competition and adult energy reserves [PDF]

open access: yes, 2010
Background Genetic modification of mosquitoes offers a promising strategy for the prevention and control of mosquito-borne diseases. For such a strategy to be effective, it is critically important that engineered strains are competitive enough to serve ...

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

open access: yesIntegrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

Changes in Site Occupancy of Marsh‐Breeding Frogs Are Associated With Surrounding Land Cover: Implications for Conservation Planning

open access: yesAnimal Conservation, EarlyView.
To help ensure the growth and persistence of frog populations, we quantified changes in frog occurrence as a function of concurrent changes in land cover in the surrounding landscape of eight marsh‐breeding frog species, or groups of species. We used data from the Great Lakes Marsh Monitoring Program delivered by Birds Canada at 377 sites across four ...

Guidelines for the emergency management of mosquito-borne disease outbreaks [PDF]

open access: yes
This document addresses three trigger events (existing diseases, natural disasters, and exotic diseases) that could necessitate an emergency response.

The Moral (Un)Desirability of New Biomedical Technologies as Potential Techno‐Fixes

open access: yesBioethics, EarlyView.
ABSTRACT The techno‐fix argument, used to argue against technological interventions that address the consequences of social problems instead of their underlying causes, is increasingly invoked in biomedical discussions. However, especially in biomedicine, the techno‐fix argument remains conceptually underdeveloped.

Mosquitoes as vectors of human disease in South Africa

open access: yesSouth African Family Practice, 2005
While malaria is the most important mosquito-borne disease in South Africa, there are also several mosquito-borne viruses that also cause human disease. The most significant are chikungunya, West Nile, Sindbis and Rift Valley fever viruses.

In the heart of the city: Trypanosoma cruzi infection prevalence in rodents across New Orleans

open access: yesParasites & Vectors, 2020
Background Trypanosoma cruzi - the causative agent of Chagas disease - is known to circulate in commensal pests, but its occurrence in urban environments is not well understood.
