[Comparison of various aspects of normal and filamentous forms of S. enteritidis]

For more detailed information on filamentous and normal forms of S. enteritidis, electronmicrographic studies and slide cultures were carried out. The filaments show similarity to normal forms of S. entertidis except for their length. They produce the normal forms of bacteria when transferred to suitable media. Some of the filaments exhibited various degrees of degeneration in their walls. Some of them consist of only a collapsed cell wall, because they lose their cell content. We think those are the filaments which are irreversible and not able to produce the normal forms of bacteria.
