FIG. 6.
Effect of the MreB inhibitor A22 on wild-type B. bacteriovorus HD100 attack-phase cells. (A) HD100 attack-phase cells after 24 h of incubation with 0 μg (a), 100 μg (b), or 200 μg (c) of A22/ml. Scale bar, 3 μm. (B) Representative electron micrographs of HD100 treated with 200 μg of A22/ml (c and d) versus untreated cells (a and b). Inclusion bodies were only observed in the A22-treated cells at this concentration. The cells were stained with 0.5% uranyl acetate. Scale bars, 1 μm.
