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

Characterization of vancomycin-resistant enterococci isolated from fecal samples of ostriches by molecular methods.
The aim of this study was to estimate the occurrence of vancomycin-resistant enterococci (VRE) in fecal samples of ostriches from a farm of Southern Portugal, the mechanisms implicated, and theExpand

Genetic detection and multilocus sequence typing of vanA-containing Enterococcus strains from mullets fish (Liza ramada).
Enterococci have emerged as important nosocomial and community-acquired pathogens in humans. The presence of vanA-enterococci was investigated in 103 fecal samples recovered from mullets fish (LizaExpand

Virulence factors in enterococci from partridges (Alectoris rufa) representing a food safety problem.
Forty-three Enterococcus isolates recovered from fecal samples of partridges, during the partridge hunting season, were studied for gelatinase and β-hemolysis activities. The presence of fsr-gelEExpand
