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

backgroundThe common palm civet (Paradoxurus musangus) is a species native to Southeast Asia. Highly adapted to urbanised environments, these civets can often be found in proximity to humans and companion animals, raising the concern of pathogen transmission at the human-wildlife and wildlife-domestic animal interface. Whilst there have been reports of various bacteria and viruses detected in civets, little is known about the protozoa that they may harbour. In this study, we screened the common palm civets in Singapore for tick-borne protozoan parasites known as piroplasms.

methodsOver a 2-year period, blood samples were opportunistically collected from 135 wild common palm civets following a physical examination. The sex and weight of each civet were recorded, and any ectoparasites detected were identified through DNA barcoding. DNA extracts of blood samples were screened using a PCR assay targeting the 18S rRNA gene of piroplasmids.

resultsA novel Cytauxzoon species was detected in 29 civets (21.5%), and a statistically significant association was found between infection and the civet's weight. Two cat flea (Ctenocephalides felis) specimens were discovered on two sampled civets; however, Cytauxzoon DNA was not detected in either the flea or the sampled civet. Phylogenetic analysis of the Cytauxzoon 18S rRNA gene sequences from 29 civets revealed that this piroplasmid is most closely related to a Cytauxzoon sp. detected in meerkats in South Africa but molecularly distinct from the six currently described Cytauxzoon species.

conclusionsThis detection documents the first molecular confirmation of Cytauxzoon sp. infection in Southeast Asia and the first report of Cytauxzoon sp. in a viverrid host. Further studies are required to determine the vector involved in the transmission of this novel Cytauxzoon species, as no ticks were found on the sampled civets. The discovery of Cytauxzoon paradoxurus n. sp. highlights the importance of expanded biosurveillance to better understand the diversity of piroplasms harboured by wildlife in the region and its potential for cross-species transmission.
