the authors studied the activity of fosfomycin ( fos ) and/or gentamicin ( gen ) against a klebsiella pneumoniae strain resistant to all beta-lactams -- except cephamycins and imipenem -- by production of a plasmid mediated extended broad-spectrum beta-lactamase-tem-3 , to all aminoglycosides -- except gentamicin -- by production of a plasmid mediated 6 ' aminoglycoside acetyltransferase iv , to sulfonamides and to tetracyclines .
