Determination of the designed primer specificity. M, ladder; 1, P. aeruginosa (27853); 2, Escherichia coli (ATCC 25922); 3, Staphylococcus aureus (25923); 4, Acinetobacter baumannii (19606); 5, Staphylococcus epidermidis (12228); 6, Enterococcus faecalis (29212). Expected fragments corresponded to the primers of the four genes only amplified in the presence of the P. aeruginosa (27853) genomic DNA
