Narrow is the way. It is important to know what bacteria is causing an infection. The microbiology staff (unsung heroes) cannot only identify the bacteria but can inform the doctor about which is the best antibiotic to use. Therefore, we are able to narrow our antibiotic coverage to target this bacteria.
