Determining the Minimum Inhibitory Concentration of Enrofloxacin Against Avian Pathogenic E. coli

Executive Industry Relevance

Determining the minimum inhibitory concentration (MIC) of enrofloxacin against avian pathogenic E. coli (APEC) is critical for establishing quantitative thresholds that inform early-stage anti-infective discovery and development. MIC testing provides predictive confidence for compound efficacy, supports mechanistic de-risking, and enables data-driven portfolio triage in veterinary pharmaceutical pipelines. This approach underpins translational continuity from in vitro screening to preclinical model selection for infectious disease programs targeting Gram-negative pathogens.
