Biofilm Development on Urinary Catheters Promotes the Appearance of Viable but Nonculturable Bacteria
نویسندگان
چکیده
Several antimicrobial urinary catheter materials have been developed, but, although laboratory studies may show a benefit, none significantly improved clinical outcomes. The use of poorly designed testing and lack consideration the impact VBNC populations be responsible.

The 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 کاملViable but Nonculturable Bacteria: Food Safety and Public Health Perspective
The viable but nonculturable (VBNC) state is a unique survival strategy of many bacteria in the environment in response to adverse environmental conditions. VBNC bacteria cannot be cultured on routine microbiological media, but they remain viable and retain virulence. The VBNC bacteria can be resuscitated when provided with appropriate conditions. A good number of bacteria including many human ...
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 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 کاملThe viable but nonculturable concept, bacteria in urine samples, and Occam's razor.
Discrepancies between the number of bacterial cells that can be detected by a direct counting method such as microscopy and the number that form colonies on standard media are regularly reported and extensively discussed (3). The observations of Anderson and colleagues concerning urine specimens (1) fall into this category and are without doubt of considerable interest and potential importance....
