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

backgroundAnimals coexist with complex microbiota, including bacteria, viruses, and eukaryotes (e.g., fungi, protists, and helminths). While high-throughput sequencing is commonly used to characterize bacterial communities in animal microbiota, these methods are less often applied to gut eukaryotic composition. Here we used shotgun metagenomic sequencing to characterize eukaryotic diversity in the microbiomes of wild baboons and tested the degree to which eukaryotic community composition was predicted by host social group membership, sex, age, sequencing depth, and season of sample collection.

resultsWe analyzed a total of 75 fecal samples collected in 2012 and 2014 from 73 wild baboons in the Amboseli ecosystem in Kenya. DNA from these samples was subjected to shotgun metagenomic sequencing, revealing members of the kingdoms Protista, Chromista, and Fungi in 90.7%, 46.7%, and 20.3% of all samples, respectively (percentages indicate the percent of samples in which each kingdom was observed). Social group membership explained 11.2% of the global diversity in gut eukaryotic species composition, but we did not detect statistically significant effects of season, host age, or host sex. Across samples, the most prevalent protists were Entamoeba coli (74.66% of samples), Enteromonas hominis (53.33% of samples), and Blastocystis subtype 3 (38.66% of samples), while the most prevalent fungi included Pichia manshurica (14.66% of samples), and Ogataea naganishii (6.66% of samples).

conclusionsProtista, Chromista, and Fungi are common members of the gut microbiome of wild baboons. More work on eukaryotic members of primate gut microbiota is important for primate health monitoring and management strategies.
