Figure 6. Kinetics of Stenotrophomonas maltophilia adherence to plastic. (A) As early as 30 min, individual bacteria have attached to the plastic surface and formed small clumps (arrows). (B–D) As incubation time proceeds for 1 (B), 2 (C), and 4 (D) h, the number of attached bacteria increases throughout the abiotic surface. (E) At 6 h, the bacterial monolayers progress into three-dimensional microcolonies (arrows). (F) After 18 h, the microcolonies have formed true bacterial communities. No obvious differences were noted beyond this incubation period. Magnification 400x.
