WebSep 13, 2024 · Biofilms are communities of aggregated, matrix-embedded microbial cells showing a high tolerance to an in principle adequate antibiotic therapy, often resulting in treatment failure. A major challenge in the management of biofilm-associated infections is the development of adequate, standardized biofilm susceptibility testing assays that are … WebFeb 24, 2024 · 1. Some of the other media commonly used for static biofilm assays are LB, Mueller-Hinton broth (MHB), and M9 minimal medium [ 10 ]. Nutrient-rich media such as LB and MHB are preferred since they provide enhanced growth of A. baumannii. Since NB is used for motility and other phenotypic studies, it is often used.
