Abstract

109J attached to both capsulated and noncapsulated K29 cells. Electron microscopy revealed penetration of the thick polysaccharide capsule without any major disintegration of the neighbouring capsular matrix. The capsule remained intact during bdelloplast formation and lysis was unaffected by capsulation of the prey cell. This study shows that, in contrast to its effect on bacteriophage penetration and its protective activities against immune defence mechanisms, the capsule of does not serve as a barrier against invasion by .
