Fig. 1From: In vitro investigation of relationship between quorum-sensing system genes, biofilm forming ability, and drug resistance in clinical isolates of Pseudomonas aeruginosaResults of microtiter plate (MTP) assay. Columns 1–10 and 13–22 represent the biofilm forming ability of tested isolates in triplicate. Columns 11 and 23 represent positive control (P. aeruginosa ATCC 27853). Columns 12 and 24 represent negative control (sterile tryptic soy broth medium)Back to article page
