Antimicrobial Resistance and Biofilm in Bacteria from Rehabilitated Sapajus libidinosus.
Article in EcoHealth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Antimicrobial resistance (AMR) in natural environments and wildlife is an escalating threat to global health and biodiversity conservation. Neotropical primates of the genus Sapajus may act as reservoirs and ecological sentinels of resistant bacteria. The absence of systematic microbiological screening in wildlife rehabilitation centers, coupled with empirical antimicrobial use, can facilitate resistance spread in vulnerable ecosystems. This study characterized phenotypic and genotypic resistance profiles and biofilm-forming ability of Staphylococcus spp. and Mammaliicoccus sciuri isolated from Sapajus libidinosus undergoing rehabilitation in Northeastern Brazil. Rectal swabs were collected, and bacterial isolates identified by MALDI-TOF MS, followed by antimicrobial susceptibility testing, molecular detection of resistance genes, and biofilm assays. Nineteen isolates were recovered: 63.2% Staphylococcus spp. and 36.8% Mammaliicoccus spp. The predominant species were M. sciuri (36.8%) and S. simiae (31.6%). Rates of resistance to penicillin (63.2%) and tetracycline (57.9%) were the most frequent. The main resistance genes detected included tetM (36.8%), tet(38) (31.6%), blaZ (26.3%), msrA (26.3%), and mecA (5.3%). Perfect agreement existed between mecA presence and cefoxitin resistance (κ = 1.00; p < 0.01), with moderate agreement between msrA and non-susceptibility to erythromycin and clindamycin (j= 0.56; p = 0.0265). Biofilm production was mostly weak (94.7%), with moderate production in one isolate. Multidrug resistance occurred in 21.1% of isolates. This pioneering Brazilian study highlights wildlife rehabilitation centers as critical hotspots for AMR surveillance and contributes to understanding the ecological health and conservation of Neotropical primates.
