Fecha de publicación: | 2004 | Publicación seriada: | FEMS Microbiology Letters | Resumen: | The effect of salicylate, a marRAB inducer, on the resistance to beta-lactams was characterized in an AmpC beta-lactamase hyperproducer Morganella morganii clinical isolate (the M1 strain). Results were compared with those of the effect of salicylate in a wild-type M. morganii strain. Salicylate induced a decreased susceptibility to nalidixic acid, norfloxacin and tetracycline and simultaneously increased the susceptibility to beta-lactams apparently due to the repression of AmpC P-lactamase synthesis in the M1 strain. Likewise, salicylate only repressed 46 kDa outer membrane protein expression in the wild-type strain, since the clinical isolate M1 did not express it. | URI: | http://hdl.handle.net/10553/49971 | ISSN: | 0378-1097 | DOI: | 10.1016/j.femsle.2004.07.030 | Fuente: | FEMS Microbiology Letters[ISSN 0378-1097],v. 238(1), p. 139-144 (Septiembre 2004) |
