Data obtained from 1996 to 2002 on 13 patients with Rhizobium radiobacter infections were analyzed. Ten patients (76%) had underlying hematological malignancy or solid- organ cancer. Six patients (46%) had febrile neutropenia during the course of R. radiobacter infection. The majority (54%) of infections were catheter-related bacteremia, and 92% of infections were hospital acquired. All the patients survived. Eighteen isolates were recovered from the 13 patients, and each isolate was susceptible to cefepime, piperacillin-tazobactam, carbapenems, and ciprofloxacin. The pulsed-field gel electrophoresis profiles differed among the isolates recovered from different patients, indicating the absence of nosocomial spread of the organism.

    The article discusses the use of cephalexin in the management of bacteriuria. Cephalexin appears to be one of several good drugs for the treatment of bacteriuria in that it is bactericidal, is tolerated well, is absorbed well orally, and is excreted in high levels in the urine. Researcher found...
