The individual has been confirmed to have HAP/VAP or cIAI and requires intravenous antibiotic treatment.
results are provided at screening and every visit during the study
Symptoms developing more than 48 hours after someone is admitted to a care facility or within 7 days after they are discharged are more likely to be caused by something other than the care facility.
An infiltrate is an accumulation of fluid in the lungs
A respiratory specimen was obtained from a patient who was experiencing symptoms and then was randomly assigned to a group.
