Cytopathogenesis of Naegleria fowleri Thai strains for cultured human neuroblastoma cells.
Article in Parasitology research, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The aim of this study is to evaluate cellular interaction between free-living amoebae Naegleria fowleri strains and mammalian target cells in vitro. Two Thai strains of N. fowleri; Khon Kaen strain from the environment and Siriraj strain from the patient's cerebrospinal fluid and the Center of Disease Control VO 3081 strain from Atlanta (US) were studied. Human neuroblastoma (SK-N-MC) and African Green monkey Kidney (Vero) cells were used as target cells. Each cell line was inoculated with each strain of N. fowleri at a ratio of 1:1 and observed for 7 days. The uninoculated target cells and each strain of N. fowleri were used as control. The numbers of the challenged and unchallenged cells as well as the free-living amoebae were counted three times by trypan blue exclusion method. The inoculation began when the amoebae attached to the cell membrane and ingested the target cells. In this study, extensive cytopathogenesis with many floating inoculated cells and abundant number of amoebae were observed. The destruction pattern of both inoculated SK-N-MC and Vero target cells were similar. Interestingly, SK-N-MC was more susceptible to N. fowleri strains than the Vero cell. In addition, N. fowleri Siriraj strain showed the highest destruction pattern for each target cell. Our findings suggest that the SK-N-MC should be used as a base model for studying the neuropathogenesis in primary amoebic meningoencephalitis patients.
