One Health Genomic Analysis of Methicillin-Resistant Staphylococcus spp. From Humans, Cats, and Dogs in a Veterinary Hospital in Central Chile.

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
introductionThe emergence of methicillin-resistant Staphylococcus species (MRS) poses a growing threat to both human and veterinary health.
methodsWe performed a comparative genomic characterisation of 49 methicillin-resistant Staphylococcus isolates collected from humans, dogs, and cats in a veterinary hospital from Central Chile.
resultsWhole-genome sequencing revealed S. aureus, S. pseudintermedius, and S. epidermidis as the most prevalent species, with distinct patterns of antimicrobial resistance and virulence. Average Nucleotide Identity (ANI) and phylogenetic analyses highlighted species-specific clustering but also revealed divergent lineages among Staphylococcus aureus and Staphylococcus epidermidis isolates. Resistance to β-lactams was widespread, with the blaZ and mecA genes predominating, while macrolide and aminoglycoside resistance genes were variably distributed. S. aureus exhibited the highest virulence gene content, whereas S. pseudintermedius isolates carried superantigen-encoding enterotoxin genes, suggesting potential zoonotic risk. MLST and SCCmec typing confirmed the circulation of community-associated MRS lineages, notably SCCmec type IV.
conclusionsThis study provides a first comprehensive characterisation of methicillin-resistant Staphylococcus spp. isolates from human and animal hosts at a veterinary hospital in Santiago, Chile. These findings underscore the need for continuous surveillance under the One Health approach to monitor the potential transmission of high-risk clones and resistance determinants between humans and companion animals.
