Rectal swabs from 2469 hospital and community participants were inoculated onto CHROMagar ESBL.

When evaluated for phenotypic susceptibilities (VITEK-2), 88.1\u200a% (714\/810) of the isolates recovered on the selective agar exhibited resistance to third-generation cephalosporins.<\/jats:p>\n \n Conclusion.<\/jats:bold> The performance characteristics of CHROMagar ESBL media suggest that they may be a viable screening tool for the identification of ESCrE from hospitalized and community participants and could be used to inform infection prevention and control practices in Botswana and potentially other low-and middle-income countries (LMICs). Further studies are required to analyse the costs and the impact on time-to-result of the media in comparison with available laboratory methods for ESCrE surveillance in the
