The importance of the viable but non-culturable state in human bacterial pathogens
Many bacterial species have been found to exist in a viable but non-culturable (VBNC) state since its discovery in 1982. VBNC cells are characterized by a loss of culturability on routine agar, which impairs their detection by conventional plate count techniques. This leads to an underestimation of total viable cells in environmental or clinical samples, and thus poses a risk to public health. ...
متن کاملDetection of Viable But Non-Culturable State of Escherichia coli O157:H7 Using Reverse Transcription PCR
Background and Aims: Many bacteria including Escherichia coli may enter into a viable but non-culturable (VBNC) state under unfavorable stresses, which are unable to be detected by culture-based methods. In this study, the use of Reverse Transcription PCR (RT-PCR) for detection of VBNC state of E. coli O157:H7 was investigated. Materials and Methods: Escherichia. coli O157:H7 was inoculated i...
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 کاملCurrent Perspectives on Viable but Non-culturable State in Foodborne Pathogens
The viable but non-culturable (VBNC) state, a unique state in which a number of bacteria respond to adverse circumstances, was first discovered in 1982. Unfortunately, it has been reported that many foodborne pathogens can be induced to enter the VBNC state by the limiting environmental conditions during food processing and preservation, such as extreme temperatures, drying, irradiation, pulsed...
متن کاملAntibiotic pressure can induce the viable but non-culturable state in Staphylococcus aureus growing in biofilms.
OBJECTIVES Staphylococcal biofilms are among the main causes of chronic implant-associated infections. We have recently suggested that their transformation into viable but non-culturable (VBNC) forms (i.e. forms capable of resuscitation) could be responsible for the recurrent symptoms. This work aims to establish whether Staphylococcus aureus biofilms can give rise to VBNC forms capable of bein...
