The ability to enter into an avirulent viable but non-culturable (VBNC) form is widespread among Listeria monocytogenes isolates from salmon, patients and environment
Media-based bacteriological testing will fail to detect non-culturable organisms and the risk of consuming viable but non-culturable (VBNC) Listeria monocytogenes is unknown. We have here studied whether L. monocytogenes obtained from seafoods, processing environment and clinical cases enter the VBNC state and assessed the virulence of the non-culturable forms of the bacteria. A number of 16 L....
متن کاملCurrent Perspectives on Viable but Non-Culturable (VBNC) Pathogenic Bacteria
Under stress conditions, many species of bacteria enter into starvation mode of metabolism or a physiologically viable but non-culturable (VBNC) state. Several human pathogenic bacteria have been reported to enter into the VBNC state under these conditions. The pathogenic VBNC bacteria cannot be grown using conventional culture media, although they continue to retain their viability and express...
متن کاملViable but Non-culturable Bacteria: Clinical Practice and Future Perspective
In this editorial, the importance of VBNC in clinical practice and future researches interests has been pinpointed. Accurate detection of VBNC, especially for major mentioned pathogens, is the future research gap.
متن کاملDifferential Resuscitative Effect of Pyruvate and its Analogues on VBNC (Viable But Non-Culturable) Salmonella
An environmental isolate of Salmonella Enteritidis (SE), grown to the logarithmic phase, rapidly lost culturability by the addition of 3 mM H2O2 to cultures grown in Luria-Bertani (LB) medium; however, some H2O2-treated bacteria regained their culturability in M9 minimal medium, if sodium pyruvate was present at at least 0.3 mM. In addition, most pyruvate analogues, such as bromopyruvate or phe...

Background and Aims: The purpose of this study was to investigate the possibility of Listeria monocytogenes entering the VBNC state during the frozen storage and the expression of its pathogenic genes Materials and Methods: Bacteria in 106 Colony counts of in mid log phase were inoculated into three Culture medium including Normal Saline (NS), BHI Broth and Fish Broth (FB) and kept at -18ºCfor...
