The viable but nonculturable state in bacteria.
It had long been assumed that a bacterial cell was dead when it was no longer able to grow on routine culture media. We now know that this assumption is simplistic, and that there are many situations where a cell loses culturability but remains viable and potentially able to regrow. This mini-review defines what the "viable but nonculturable" (VBNC) state is, and illustrates the methods that ca...
متن کاملThe viable but nonculturable state and cellular resuscitation
Aquatic microbial ecologists have long recognized that portions of bacterial populations seem to disappear from natural water bodies during certain times of the year, only to reappear at other times. In the case of V. vulnificus, numerous studies have documented the difficulty researchers experience in culturing this bacterium during cold months, presumably due to “die-off” of the population. T...
متن کاملResuscitation of Vibrio vulnificus from the Viable but Nonculturable State.
Like many other gram-negative bacteria, the human pathogen Vibrio vulnificus is induced into a viable but nonculturable (VBNC) state by incubation at low temperatures. The ability of any bacterium to resuscitate from this dormant state would appear to be essential if the VBNC state is truly a survival strategy. The question as to whether the culturable cells which appear following removal of th...
متن کاملThe viable but nonculturable state and starvation are different stress responses of Enterococcus faecalis, as determined by proteome analysis.
The protein expression patterns of exponentially growing, starved, and viable but nonculturable (VBNC) Enterococcus faecalis cells were analyzed to establish whether differences exist between the VBNC state and other stress responses. The results indicate that the protein profile of VBNC cells differs from that of either starved or exponentially growing bacteria. This demonstrates that the VBNC...
متن کاملThe viable-but-nonculturable state induced by abiotic stress in the biocontrol agent Pseudomonas fluorescens CHA0 does not promote strain persistence in soil.
The effects of oxygen limitation, low redox potential, and high NaCl stress for 7 days in vitro on the rifampin-resistant biocontrol inoculant Pseudomonas fluorescens CHA0-Rif and its subsequent persistence in natural soil for 54 days were investigated. Throughout the experiment, the strain was monitored using total cell counts (immunofluorescence microscopy), Kogure's direct viable counts, and...
