Staling in bacterial cultures.
When a strain of bacteria is streaked on a nutrient agar or gelatin medium containing a large number of its own viable cells, no growth appears even after long incubation. Eijkman (1904) and Powers and Levine (1937) suggested that this phenomenon of "staling" was due to specific, autoinhibitory substances and that it might serve as a basis for selective and differential techniques in determinat...
متن کاملBasal Bodies of Bacterial In
This paper investigates further the question of whether the flagella of Proteus mirabilis emerge from basal bodies. The bacteria were grown to the stage of swarmer differentiation, treated lightly with penicillin, and then shocked osmotically. As a result of this treatment, much of the cytoplasmic content and also part of the plasma membrane were removed from the cells. When such fragmented org...

متن کاملMaintenance of Bacterial Cultures
^ In most laboratories in the North American Continent and in England, the older methods of Maintaining bacterial cultures by constant subculturing in suitable media have of recent years been largely superseded by the method of rapid freezing and dehydration in vacuo. As early as 1896, Martin suggested the possibility and Procedure involved in the preservation of guinea-pig complement in the dr...
متن کاملSpiral intercellular calcium waves in hippocampal slice cultures.
Complex patterns of intercellular calcium signaling occur in the CA1 and CA2 regions of hippocampal slice organotypic cultures from neonatal mice. Spontaneous localized intercellular Ca2+ waves involving 5-15 cells propagate concentrically from multiple foci in the stratum oriens and s. radiatum. In these same regions, extensive Ca2+ waves involving hundreds of cells propagate as curvilinear an...
