Liver abscess caused by Brevundimonas vesicularis in an immunocompetent patient.

abstract：PURPOSE:In an increasing number of cases the last therapeutic option for treatment of carbapenem-resistant Enterobacteriaceae is colistin. As the detection of colistin resistance is problematic and time-consuming, it is desirable to find a rapid and reliable test. The rapid polymyxin NP test developed by Nordmann et al...
