Eligibility Criteria
Criteria
Inclusion Criteria:
-

-
Women of childbearing age having negative pregnancy test at the time of enrollment and agreeing to take effective contraceptive measures from the delivery to 7 ~14 days after stopping .

-
Pathogens are or highly suspected to be aerobic gram-negative bacilli.
-
Before 72h of admin agents, drug treatment which used for Systemic antibacterial activity against gram-negative bacteria,is less than 48 hours. If it was more than 48h, there must be evidence for clinic failure, eg. continue fever.WBC and neutrophils irregular, or respiratory secretions/blood bacterial culture are positive.
-
Informed consent granted.
Exclusion Criteria:
