Abstract

FMV 1953 uropathogenic Escherichia coli isolate was extremely resistant to amoxicillin, co-amoxiclav, ticarcillin, mecillinam, cefoxitime, cefixime, cefuroxime, cefotaxime, ceftazidime, ceftriaxone and aztreoname. From the resistance patterns observed we deduce the phenotype as producing a TEM-1 β -lactamase, a hyperproduced Amp-C β-lactamase and an OXA-3 β-lactamase or a PBP-2 mutation isolate.

 

Key words: Antibiotic resistance, uropathogenic Escherichia coli, phenotype characterization.
