Capsule production by capsule mutants.
Maneval stain of cells from 24 h capsule-inducing cultures. G9241 (A, B), ΔhasACB (C, D), ΔwchA (E, F), Δwzy (G, H), ΔwchJ (I, J), Δwzg (K, L), and ΔwchAΔhasACB (M) cells were either untreated (A, C, E, G, I, K, M) or treated with 200 U of hyaluronidase (B, D, F, H, J, L) prior to application of Maneval stain. Cells were visualized with oil immersion at 1,000x magnification.
