Mobile phone camera could be used to detect bacteria
Researchers say they can now locate potential sources of infection.
Scientists have developed a new technique for locating sources of infection. Using fluorescent markers, they may even be able to detect cells using a mobile phone camera.
Quickly identifying the harmful bacteria responsible for a serious medical or dental conditions can be difficult and costly.
The research was a collaborative effort by the University of Nottingham and GSK Consumer Healthcare. Their initial focus was dental healthcare, finding ways to target bacteria that cause dental cavities and periodontal disease.
As the research progressed, however, GSK principle scientist David Churchley, said: "We saw that our research had broader implications and potential for a wider range of uses."
The research team say they can pinpoint the source of an infection by "hijacking" the processes of pathogens, revealing their location.
Fluorescent markers are used to tag these cells, allowing scientists to detect them using a mobile phone camera.
Professor Cameron Alexander, who led the research at the university's School of Pharmacy, said the technique could be used for "point-of-care diagnostics for pathogenic bacteria".
The Greyhound Board of Great Britain has published new vaccination guidance, with all greyhounds registered from 1 January, 2027 required to have the L4 leptospirosis vaccination, rather than L2.
