Table 1.
Collection of Burkholderia isolates screened for antimicrobial activity. Isolates were screened for antimicrobial activity against Staphylococcus aureus ATCC 29213, Acinetobacter baumannii LMG 10520, and Candida albicans SC5314 using an overlay assay. Antimicrobial activity was defined as an inhibition zone diameter ≥5 mm. Isolates were assigned to Other Bcc groups by means of multilocus sequence typing analysis as described previously [31]. CLIN, clinical; ENV, environmental.
