Molecular Screening of Black Flies (Diptera: Simuliidae) for Vector-Borne Zoonotic Pathogens, South Moravia, Czech Republic.

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
introductionBlack flies (Simuliidae) are globally distributed blood-feeding arthropods and vectors of viral, bacterial, and parasitic pathogens to many animal species, including humans. We investigated the occurrence of selected vector-borne pathogens in black flies in South Moravia, Czech Republic, and evaluated their possible role in the circulation of vector-borne pathogens.
methodsA total of 11,600 black flies comprising four species of the genus Simulium, namely Simulium (Boophthora) erythrocephalum (De Geer, 1776), Simulium (Wilhelmia) lineatum (Meigen, 1804), Simulium (Wilhelmia) balcanicum (Enderlein, 1924), and Simulium (Wilhelmia) turgaicum (Rubtsov, 1940) were pooled and screened for the following arthropod-borne pathogens and parasites endemic in Central Europe: viruses (alphaviruses, bunyaviruses and flaviviruses), bacteria (Borrelia burgdorferi sensu lato, Borrelia miyamotoi, Anaplasma phagocytophilum, Neoehrlichia mikurensis, Bartonella spp., Rickettsia spp., Francisella tularensis, Coxiella burnetii, and Brucella spp.), protista (Babesia spp., Encephalitozoon spp. and Enterocytozoon spp.) and filaria (Dirofilaria spp., Setaria spp., and Onchocerca spp.).
resultsAlmost all pools were negative for known arthropod-borne pathogens and parasites. However, four new Bartonella spp. variants were found that share similarity with other bartonellae reported from diverse arthropods and humans. The phylogenetic analysis of Bartonella sequences from Czech black flies provides further evidence about an expanding diversity of Bartonella lineages in arthropods globally, including hematophagous species (e.g., ticks, mosquitoes, and biting flies) and non-hematophagous species (e.g., bees and ants). These bartonellae have the potential to cause pathogenic infections in humans who are exposed to arthropods carrying these bacteria.
conclusionsSumming up, this study provides for the very first time valuable data for characterising the risk to public and veterinary health from black flies and the infections they may carry in Europe. Further testing, however, should include a wider geographic, seasonal, and taxonomic range of black flies.
