Formation 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 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 کاملInduction and resuscitation of viable but nonculturable Salmonella enterica serovar typhimurium DT104.
Salmonella enterica serovar Typhimurium DT104 11601 was tested for its ability to maintain viability in minimal, chemically defined solutions. Periodic monitoring of growth and survival in microcosms of different ion concentrations, maintained at various temperatures, showed a gradual decline in culturable organisms ( approximately 235 days) at 5 degrees C. Organisms maintained at a higher temp...
متن کاملPhysiological 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...
