Molecular evidence of potential novel spotted fever group rickettsiae, Anaplasma and Ehrlichia species in Amblyomma ticks parasitizing wild snakes.
Article in Parasites & vectors, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
backgroundAmblyomma ticks parasitize a wide range of animals in tropical regions. This study describes the identification of Amblyomma ticks from wild snakes in Malaysia and the detection of potential human pathogens such as Rickettsia, Anaplasma, Ehrlichia and bartonellae in the ticks.
findingsTwenty one adult ticks (twelve A. varanense and nine Amblyomma helvolum ticks) identified from seven Python molurus snakes in Sepang and a pool of six A. helvolum ticks from a Naja sumatrana snake in Johore, Malaysia were investigated in this study. Amplification of the citrate synthase (gltA), 190-kDa surface antigen gene (ompA), 135-kDa surface antigen (ompB) and surface cell antigen (sca4) genes followed by sequence analysis confirmed the presence of two potential novel spotted fever group rickettsiae in the ticks. Candidatus Rickettsia sepangensis from an engorged A. varanense tick demonstrated high sequence similarity to Rickettsia tamurae; while Candidatus Rickettsia johorensis from two samples (individual and pooled) of A. helvolum and two A. varanense ticks were closely related to Rickettsia raoultii. Anaplasma and Ehrlichia DNA were detected from seven and two ticks, respectively. No bartonellae was detected from any of the ticks.
conclusionThe finding in this study suggests that Amblyomma ticks parasitizing wild snakes may serve as reservoir hosts and carriers for rickettsioses, anaplasmosis and ehrlichiosis in this region.
