1 · What the graph read from it

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.

2 · The registry

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

backgroundNaegleria spp. is a free-living amoeba of which some species including N. fowleri and N. australeinsis are highly pathogenic in human and animals. These widespread amoebae could be found in different environmental sources particularly in aquatic resources of tropical and subtropical regions. The most important source of infection is via recreational water contact. Due to the lack of thorough research regarding species of Naegleria spp. in aquatic sources, the present study was conducted.

methodsIn the present study, 60 samples were collected from recreational water resources of Rasht city, Guilan province, north of Iran. After filtering and culturing the samples, plates were examined by microscopic method and according to the page criteria. DNA of vahlkampfiid-positive samples were then extracted using phenol-chlorophorm method. Amoebae genus was identified by targeting the ITS-region and sequencing based-approaches.

resultsNine (15%) samples out of a 60 total samples were positive for Naegleria spp. of which seven belonged to potentially pathogenic N. australiensis. Two other strains were belonged to non-pathogenic N. pagei.

conclusionThe present research was the first report of occurrence of N. australiensis and N. pagei in Rasht city, north Iran. This study reflects the occurrence of Naegleria spp. in water sources of Guilan Province, Iran.
