Martinez-Puchol, Sandra ; Gomes, Cláudia ; Pons, Maria J. ; Ruiz-Roldan, Lidia ; Torrents de la Pena, Alba ; Ochoa, Theresa J. ; Ruiz, Joaquim | Wiley | 2019-02-06T14:52:12ZFurazolidone-resistant mutants were obtained from four clinical isolates of diarrhoeagenic Escherichia coli. The stability of the resistance and the frequency of mutation were established. The minimal inhibitory concentration of furazolidone, ni[...]texto impreso
