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

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

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

Wild boars as reservoirs of extended‐spectrum beta‐lactamase (ESBL) producing Escherichia coli of different phylogenetic groups
ESBL‐producing E. coli isolates have been isolated from eight of seventy seven faecal samples (10.4%) of wild boars in Portugal. The ESBL types identified by PCR and sequencing were blaCTX‐M‐1 (6Expand
