Occurrence of Antimicrobial-Resistant Escherichia coli in Marine Mammals of the North and Baltic Seas: Sentinels for Human Health

Stephanie Gross et al.

Summary: Antimicrobial resistance is a global health threat with wildlife acting as a reservoir and vector for resistant bacteria and genes. This study found resistant strains of Escherichia coli in marine mammals of the North and Baltic Seas, highlighting their role as sentinels for antimicrobial-resistant bacteria. The distribution of resistant bacteria in these sea areas provides important information from a One Health perspective.

A new multidrug-resistant enterotoxigenicEscherichia colipulsed-field gel electrophoresis cluster associated with enrofloxacin non-susceptibility in diseased pigs

M. de Lagarde et al.

Summary: The study described temporal trends in Escherichia coli pathotypes and antimicrobial resistance in pig cases in Quebec from 2008 to 2016. A high-risk ETEC:F4 clone has been spreading in the pig population in Quebec since 2015, highlighting the importance of surveillance and control strategies for identifying new clones.

Detection of blaOXA-1, blaTEM-1, and Virulence Factors in E. coli Isolated From Seals

Ana P. Vale et al.

Summary: Marine mammals serve as sentinels for understanding the health of marine and coastal environments, highlighting the presence and spread of antimicrobial resistance. This study detected resistance genes and virulence factors in E. coli isolates from rescued seals, emphasizing the importance of marine mammals in monitoring AMR.

Surveillance for Antibiotic-Resistant E. coli in the Salish Sea Ecosystem

Alexandria Vingino et al.

Summary: The study isolated E. coli from the Salish Sea ecosystem and found resistance to antibiotics in isolates. The proportion of antibiotic-resistant isolates from animal samples was significantly higher than those from marine water samples, suggesting that animals may serve as potential sentinels for antibiotic-resistant and ExPEC E. coli in the Salish Sea ecosystem.

Presence of β-Lactamase-producing Enterobacterales and Salmonella Isolates in Marine Mammals

Olivia M. Gruenzweil et al.

Summary: The study aimed to investigate the presence of ESBL- and AmpC-producing Enterobacterales, as well as Salmonella, in marine mammals. Results revealed a high prevalence of multidrug-resistant bacteria and pandemic high-risk clones, indicating anthropogenic antimicrobial pollution in these animals.

Plasmid-associated antimicrobial resistance and virulence genes in Escherichia coli in a high arctic reindeer subspecies

Marianne Sunde et al.

Summary: In this study, antimicrobial-resistant Escherichia coli were detected in wild reindeer from the Svalbard High Arctic Archipelago. The research revealed the role of plasmids in the transmission of resistance and virulence genes, showing that these resistant bacteria may enter extreme environmental ecosystems through migrating birds, marine animals, or human activities such as tourism.
