Investigating the impact of endemic mosquitoes and invasive Aedes species on the circulation of Dirofilaria nematodes.
Article in Parasites & vectors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMosquito-borne pathogens represent a growing challenge driven by environmental changes and the spread of invasive Aedes mosquitoes. Among pathogens endemic in Europe, Dirofilaria nematodes are of particular concern due to the increasing number of human infections. To understand their zoonotic potential, we aimed to assess the prevalence of filarioid nematodes in mosquitoes and reveal the potential vector species, considering their feeding behavior.
methodsMosquitoes were collected from urban/suburban environments (Pécs, Hungary) in 2022-2023 and tested for the presence of filarioid nematodes using polymerase chain reaction (PCR) and DNA sequencing. Estimated infection rates with 95% CI were calculated, and descriptive statistics were applied.
resultsAmong 1015 tested mosquito pools (belonging to 21 species), 30 were positive for filarioid nematodes, including D. repens, D. immitis, Setaria tundra, and Setaria labiatopapillosa, with the highest prevalence and widest distribution of S. tundra. We revealed hotspots in the city where multiple filarioid species occurred. The presence of D. repens, relevant for humans, was confirmed in urban and suburban areas and near human infection cases. Among mosquitoes, Aedes vexans showed the highest positivity, harboring all identified parasites, while invasive Aedes albopictus and Aedes koreicus showed minimal/no infections. Moreover, we identified S. labiatopapillosa in urban areas in Hungary for the first time.
conclusionsOur findings highlight the potential role of Ae. vexans in transmission dynamics, while no evidence was found for the contribution of invasive mosquitoes, likely due to local environmental and behavioral factors. Our results emphasize the need for targeted vector monitoring and research to understand mosquito-borne parasites' epidemiology and public health implications, particularly in regions affected by invasive mosquitoes.
