Investigating antibiotic use in acute care patients
... said for this reason it is important to develop a molecular
detection method that can identify antibiotic resistance signatures of entire microbial communities. "Our hope is that this kind of information will equip clinicians to better manage prescribing of antibiotics." This latest research is being pl...
