Sir,
In recent years, infections due to Escherichia coli harbouring extended-spectrum β-lactamases (ESBLs) of the CTX-M classes have dramatically increased among human populations, particularly in the community setting.1 There exist just a few previous reports in which ESBLs were detected in faecal E. coli isolates of wild animals,2 but, to our knowledge, never in faecal E. coli isolates of buzzards (Buteo buteo).
Thirty-three faecal samples from buzzards of Portugal were recovered from September 2007 to February 2008 and were studied for the presence of ESBL-producing E. coli isolates. All the
