Viable 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 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 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...
متن کاملViable but non-culturable state (VBNC) of Escherichia coli related to EnvZ under the effect of pH, starvation and osmotic stress in sea water.
When exposed extreme environmental conditions such as sea water, bacteria have been shown different survival strategy for continue their life. One of this strategy known as viable but nonculturable (VBNC) state which is very important for nondifferiation bacteria. VBNC cells cause serious human health problems. Little is known, however, about the genetic mechanisms underlying the VBNC state. Un...
متن کاملThe Molecularly Crowded Cytoplasm of Bacterial Cells: Dividing Cells Contrasted with Viable but Non-culturable (VBNC) Bacterial Cells.
In this perspective, we discuss the cytoplasm in actively growing bacterial cells contrasted with viable but nonculturable (VBNC) cells. Actively growing bacterial cells contain a more molecularly crowded and organized cytoplasm, and are capable of completing their cell cycle resulting in cell division. In contrast, nutrient starving bacteria in the physiological VBNC state are struggling to su...
