Prevalence of antimicrobial resistance and resistance genes in faecal Escherichia coli isolates recovered from healthy pets.
Faecal samples of healthy dogs (n=39) and cats (n=36) obtained in Northern Portugal were seeded on Levine agar plates, and two Escherichia coli isolates per sample were recovered (78 of dogs and 66Expand

Prevalence of extended-spectrum beta-lactamase-producing Escherichia coli isolates in faecal samples of broilers.
Seventy-six faecal samples were obtained from broilers at slaughterhouse level in Portugal. Samples were inoculated on cefotaxime-supplemented Levine agar plates. Cefotaxime-resistant EscherichiaExpand

Antimicrobial resistance and the mechanisms implicated in faecal enterococci from healthy humans, poultry and pets in Portugal.
Antimicrobial resistance and the mechanisms implicated were studied in 440 enterococci (227 Enterococcus faecium, 177 Enterococcus faecalis, 32 Enterococcus hirae and 4 Enterococcus durans) recoveredExpand

Seagulls of the Berlengas Natural Reserve of Portugal as Carriers of Fecal Escherichia coli Harboring CTX-M and TEM Extended-Spectrum Beta-Lactamases
ABSTRACT Escherichia coli isolates containing the following extended-spectrum beta-lactamases have been detected in 11 of 57 fecal samples (19.3%) in Berlengas Island seagulls: TEM-52 (eightExpand

Characterization of antibiotic resistance genes and virulence factors in faecal enterococci of wild animals in Portugal.
Antibiotic susceptibility was tested in 140 non-selected enterococci (73 Enterococcus faecalis, 45 E. faecium and 22 of other species) recovered from faecal samples of 77 wild animals in Portugal.Expand

Potential impact of antimicrobial resistance in wildlife, environment and human health
Given the significant spatial and temporal heterogeneity in antimicrobial resistance distribution and the factors that affect its evolution, dissemination, and persistence, it is important toExpand

Mechanisms of antibiotic resistance in Escherichia coli isolates recovered from wild animals.
Seventy-two fecal samples obtained from wild animals in Portugal were sampled on Levine agar plates (non-supplemented with antibiotics), and Escherichia coli isolates were recovered from 56 of themExpand

Genetic characterization of extended-spectrum beta-lactamases in Escherichia coli isolates of pigs from a Portuguese intensive swine farm.
There is a great concern by the emergence and the wide dissemination of extended-spectrum beta-lactamases (ESBLs) among animal Escherichia coli isolates. We intended to determinate the carriage levelExpand

Mechanisms of quinolone action and resistance: where do we stand?
Quinolone antibiotics represent one of the most important classes of anti-infective agents and, although still clinically valuable, their use has been compromised by the increasing emergence ofExpand

Wild birds as biological indicators of environmental pollution: antimicrobial resistance patterns of Escherichia coli and enterococci isolated from common buzzards (Buteo buteo).
A total of 36 Escherichia coli and 31 enterococci isolates were recovered from 42 common buzzard faecal samples. The E. coli isolates showed high levels of resistance to streptomycin andExpand
