Vancomycin-resistant Enterococcus (VRE) isolates from dogs and cats in veterinary hospitals in Brazil.
Article in BMC veterinary research, 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
backgroundIn veterinary medicine, particularly concerning dogs and cats, there is limited data regarding vancomycin-resistant Enterococcus (VRE). However, multidrug-resistant Enterococcus is frequently identified, raising concerns about the potential for spreading these resistant microorganisms to humans due to their zoonotic nature. This study aimed to identify VRE colonizing animals admitted to a veterinary hospital and to determine the presence of the major resistance genes responsible for vancomycin resistance.
resultsEnterococcus was found to carry the vanA gene in 52.54% of cases, the vanB gene in 23.73%, the vanC gene in 20.34%, and the vanE gene in 3.39%. The antimicrobials with the lowest resistance were chloramphenicol (5.08%) and ampicillin (6.78%). In contrast, the highest resistance was observed with enrofloxacin (79.66%), rifampicin (67.80%), and ciprofloxacin (61.02%). Seven Enterococcus isolates showed resistance to vancomycin as well as high-level aminoglycoside resistance (HLAR).
conclusionA total of 46 animals were found to be colonized by VRE, of which 16 were healthy. The vanA gene was the most commonly isolated (52.54%), followed by vanB (23.73%), vanC (20.34%), and vanE (3.39%). This represents the first report of the vanE gene being identified in a dog in Brazil. Among the 59 Enterococcus isolates, 84.75% (n = 50) were found to be multidrug resistant. The colonization of VRE and Enterococcus HLAR in dogs and cats poses a public health concern, as it increases the risk of environmental dissemination and has implications for One Health.
