abstract：:Hyphae of Aspergillus nidulans continued to synthesize all the major polysaccharide components of the cell wall when cycloheximide was added to cultures. In the presence of cycloheximide, hyphae did not elongate, but electron microscopy showed that the walls became thicker around the cell. The conclusion that cyclohex...

abstract：:Shigella spp. are the major cause of bacillary dysentery worldwide. The pathogenic process involves bacterial invasion and lysis of the phagocytic vacuole, followed by replication and movement within the cell cytoplasm and, ultimately, spread directly into adjacent cells.
