Physiological characterization of viable-but-nonculturable Campylobacter jejuni cells.
Campylobacter jejuni is a pathogenic, microaerophilic, gram-negative, mesophilic bacterium. Three strains isolated from humans with enteric campylobacteriosis were able to survive at high population levels (10(7) cells ml-1) as viable-but-nonculturable (VBNC) forms in microcosm water. The VBNC forms of the three C. jejuni strains were enumerated and characterized by using 5-cyano-2,3-ditolyl te...
متن کاملThe 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 کاملPotential virulence of viable but nonculturable Shigella dysenteriae type 1.
We examined a virulent strain of Shigella dysenteriae type 1 after induction into the viable but nonculturable (VBNC) state for its ability to (i) maintain the Shiga toxin (stx) gene; (ii) maintain biologically active Shiga toxin (ShT); and (iii) adhere to intestinal epithelial cells (Henle 407 cell line). PCR was used to amplify the stx gene from VBNC cells of S. dysenteriae type 1, thereby es...
متن کاملFormation and Resuscitation of Viable but Nonculturable Salmonella typhi
Salmonella typhi is a pathogen that causes the human disease of typhoid fever. The aim of this study was to investigate the viable but nonculturable (VBNC) state of S. typhi. Some samples were stimulated at 4°C or -20°C, while others were induced by different concentrations of CuSO4. Total cell counts remained constant throughout several days by acridine orange direct counting; however, plate c...
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...
