Biofilm formation in P. aeruginosa strains. Formation of biofilm in three strains of Pseudomonas aeruginosa; strain 6 (representative susceptible strain), strain 19 (representative of a multidrug resistant strain) and the ATCC 27853 (American Type Culture collection) strain which was used for comparison. It is observed that the biofilm is formed at bacterial cells of concentration of 103 cfu/ml in both the susceptible and multidrug resistant strain, which is indicated by an elevated value of OD.
