Antimicrobial spectrum
“Antimicrobial spectra. Common antimicrobial susceptibilities illustrated over a 4 quadrant chart of bacterial pathogens based on their classification of Gram‐positive versus Gram‐negative and aerobic versus anaerobic. Pathogens that do not fit into this classification scheme (ie, atypicals) are documented in the lower right hand quadrant of the chart. For the antimicrobials in the center of […]
