Occurrence and Antimicrobial Resistance Profiles of Staphylococcus spp. Strains Isolated From Healthy Stray Dogs.
Article in Veterinary medicine and science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The potential role of stray dogs as reservoirs and disseminators of zoonotic antimicrobial-resistant pathogens to humans has long been underestimated. This study aimed to assess the occurrence of antimicrobial-resistant Staphylococcus spp. strains in the ear and nasal swabs collected from stray dogs housed at the Veterinary Hospital of Local Health Authority ASL Napoli 1 Centro. Out of 306 skin samples analysed, 256 bacterial strains were isolated using selective and differential media and identified through MALDI-TOF MS technology. The antimicrobial resistance profiles of the isolated strains were determined using the Kirby-Bauer disc diffusion method on Mueller-Hinton agar, testing susceptibility to 19 antimicrobials across 10 classes. Staphylococcus spp. was isolated in 46% of cases (119/256), with Staphylococcus pseudintermedius being the most prevalent species (50%; 59/119), followed by Staphylococcus simulans (17%; 20/119) and Staphylococcus aureus (14%; 17/119). The evaluation of the antimicrobial resistance profiles revealed a great circulation of methicillin-resistant strains in the stray dog population, as highlighted by the high levels of resistance recorded for penicillin (83.2%; 99/119), cefoxitin (72.3%; 86/119) and oxacillin (62.2%; 74/119). Notably, 85% (101/119) of the isolates were classified as multidrug-resistant, being resistant to three or more antimicrobial classes. These findings suggest that stray dogs may serve as important reservoirs of multidrug-resistant staphylococci, highlighting the need for ongoing surveillance and monitoring of antimicrobial resistance in these animals, especially in the context of the One Health approach that links human, animal and environmental health.
