Figure 1.
Sequence distribution of the 1621 genes identified in the present work as up-regulated in biofilm vs. stationary phase cells.
Genes involved in: A) biological processes, B) cellular components, and C) molecular functions. The results were filtered by the number of sequences (cutoff = 40, 5, and 80, respectively).
Figure 2.
Sequence distribution of genes expressed only in biofilm-associated cells and inhibited in planktonic cells.
Genes involved in A) biological processes, B) molecular functions, and C) cellular components. The results were filtered by the number of sequences (cutoff = 1, 4, and 1, respectively).
Figure 3.
Quantification of biofilm formation by the wild-type strain (ATCC 17978) and strains with chromosomal disruptions in the genes A1S_0114, A1S_0302, A1S_1507, A1S_3168 and A1S_2042.
Figure 4.
Quantification of biofilm formation by the wild-type strain (ATCC 17978), a stable knockout mutant strain lacking the gene A1S_0114 (ATCC Δ0114), the same mutant strain containing the pET-RA plasmid (ATCC Δ0114 + PETRA), and a mutant strain containing the pET-RA plasmid harboring the A1S_0114 gene (ATCC Δ0114 + PETRA + 0114).
Figure 5.
Comparison of the expression levels of genes related to homoserine lactone synthesis (A1S_0109, A1S_0112 and A1S_0113) in the wild-type strain A. baumannii 17978 and in the A1S_0114 knock-out (KO) strain as determined by real-time qRT-PCR assays.
