AI Article Synopsis
- Infections from Shewanella spp. are on the rise, but limited DNA sequencing data hampers our understanding of these bacteria's role in human and animal infections.
- Researchers isolated and sequenced a Shewanella algae strain from a Brazilian swine farm, originally misidentified as Shewanella putrefaciens, revealing its resistance to nearly half of the tested antimicrobials.
- This study enhances our knowledge of Shewanella spp. taxonomy and underscores the public health risks posed by increasingly resistant pathogens.
Article Abstract
Background: Infections caused by Shewanella spp. have been increasingly reported worldwide. The advances in genomic sciences have enabled better understanding about the taxonomy and epidemiology of this agent. However, the scarcity of DNA sequencing data is still an obstacle for understanding the genus and its association with infections in humans and animals.
Results: In this study, we report the first isolation and whole-genome sequencing of a Shewanella algae strain from a swine farm in Brazil using the boot sock method, as well as the resistance profile of this strain to antimicrobials. The isolate was first identified as Shewanella putrefaciens, but after whole-genome sequencing it showed greater similarity with Shewanella algae. The strain showed resistance to 46.7% of the antimicrobials tested, and 26 resistance genes were identified in the genome.
Conclusions: This report supports research made with Shewanella spp. and gives a step forward for understanding its taxonomy and epidemiology. It also highlights the risk of emerging pathogens with high resistance to antimicrobial formulas that are important to public health.
