Molecular Identification of Entamoeba spp. From Captive Proboscis Monkey (Nasalis larvatus) in Indonesia.
Article in Journal of medical primatology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInfection of Entamoeba (amoebiasis) in the proboscis monkey (Nasalis larvatus), a Bornean endemic and endangered species of non-human primates (NHPs), has not been reported in Indonesia. PURPOSE: This study aimed to identify Entamoeba from captive proboscis monkeys at Surabaya Zoo, Indonesia.
methodTwenty fecal samples were collected from captive proboscis monkeys in the study area. Fecal samples were examined through coprological and molecular methods.
findingsThe prevalence of Entamoeba spp. by coprological and molecular techniques was 90% (18/20) and 100% (20/20), respectively, with two species identified: E. coli and E. moshkovskii. Molecular analysis confirmed Entamoeba spp. and E. coli infection, which have high genetic similarity to isolates previously reported in European countries and Asia.
conclusionThis study provides the first documentation of Entamoeba spp., E. coli, and E. moshkovskii from the captive proboscis monkeys in Indonesia. This data supports ex situ health management and assesses potential cross-species transmission risks.
