Pièce de Résistance
Concerns about antimicrobial resistance most often focus on how we use antibiotics, but this is only one part of the challenge. Transmission factors can be even more important depending on the circumstances. For example, work in east Africa shows that antibiotic use, per se, provides no predictive value for having antimicrobial-resistant gut bacteria in people or animals. Instead, variables related to transmission of bacteria (e.g., consuming raw milk, sharing drinking water sources, bringing outside animals to the farm, etc.) are strongly correlated with carriage of antimicrobial-resistant bacteria. These findings highlight the importance of biosecurity to reduce disease incidence, but to also limit the transmission of resistant organisms within and between farms, communities and our health care facilities.
