Abstract

The capsules of and were examined by electron microscopy after staining with ruthenium red. They were compared with the capsule of which had previously been examined using the same procedure ( Springer & Roth, 1973 ). The capsule of had a laminated appearance. When was grown on solid medium, its capsule appeared as radially arranged projections capped by a thick electron dense layer. When grown in liquid medium, produced a capsule which showed as short thick projections with no layer external to them.
