Brief Summary:
The infection of carbapenem resistant klebsiella pneumoniae (CRKP) is increasingly serious.Based on the early experimental basis and relevant research background,this study intends to separate and purify the CRKP from the bronchoalveolar lavage fluid (BALF) of the clinical patients.Designed by checkerboard assay and time-kill assay(TKA),this study can explore the best combination therapy based on carbapenems.

Condition or disease Intervention/treatment Phase
Antibiotic Resistant Infection Drug: Fosfomycin Drug: Tigecycline Drug: Polymyxin B Early Phase 1

Detailed Description:
  1. Collect the BALF from patients diagnosed with CRKP infection in surgical intensive care unit(SICU)of Shanghai 10th people's hospital.
  2. Separate and purify the BALF. Divide each CRKP into four treatment groups based on meropenem.

3.1 By checkerboard method and microdilution broth method,get the minimal inhibitory concentration (MICS) of two antibiotics,then calculate the fractional inhibitory concentration (FIC) index according to MIC results.

3.2 Observe the effect of two antibiotics on the growth of CRKP by TKA.

4.By the above two invitro experiments, analyze the data of the experimental results and get the best combination therapy based on carbapenems.

Drug Information available for: Meropenem

Arm Intervention/treatment
Experimental: only meropenem therapy,
this group is only meropenem therapy as a single antibiotic treatment
Drug: Fosfomycin
Fosfomycin and meropenem
Other Name: meropenem

Drug: Tigecycline
Tigecycline and meropenem

Primary Outcome Measures :
  1. the fractional inhibitory concentration index (FICI) [ Time Frame: 24hours-36hours ]

    By checkerboard method and microdilution broth method,get the minimal inhibitory concentration (MICS) of two antibiotics,then calculate the fractional inhibitory concentration (FIC) index according to MIC results.

    Evaluation index:

    FIC=0.5 , coordinating effect. 0.5 < FIC <1, adding effect;

    1 < FIC <2, irrelevant.



Secondary Outcome Measures :
  1. the time-kill assay (TKA) [ Time Frame: 36hours-48hours ]
    According to the Clinical and Laboratory Standards Institute,observe the changes of bacterial growth over time after different combination therapy.
