Quantification of single- and multi-species in vitro biofilms of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (PA). (A) Quantification of single-species and multi-species biofilms of MRSA or PA using crystal violet microtiter plate assays. (B) Colony forming unit (CFU) counts of bacteria within single- and multi-species biofilms of MRSA or PA. (C) Eradication of pre-established MRSA biofilms with sodium metaperiodate (SM), DNase I and proteinase K with respect to control (untreated). (D) Eradication of PA pre-established biofilms with alginate lyase, DNase I, and proteinase K. The error bars represent the standard deviation from the mean value. The results were compared using a Student's t-test (*p < 0.05).
