High-tech imaging type can be distinguished from foodborne pathogen Campylobacter other micro-organisms as soon as 24 hours after the sample is placed in a Petri dish of fixed media, US Department of Agriculture (USDA) study published by researchers.
Researchers with the USDA's Agricultural Research Service (ARS) is used in conjunction with hyperspectral imaging, which combines with digital image processing technology for individual wavelength measurements of each image pixel is USDA ARS hundreds. Chief Scientific Research Agency.
The investigation has shown that micro-organisms cultivated on solid media perform unique äänienergian fingerprints to a particular part of the electromagnetic spectrum.Hyperspectral imager recognizes these fingerprints by measuring the light waves that bounce off or by using these objects.
Unlike the human eye to perceive that sees only the visible light, hyperspectral imaging identifies visible light and light UV, IR Hyperspectral imaging near regions. may also be applied to other identification of the agent.
Campylobacter infections in humans foodborne illness are bacteria, as well as significant in the United States and other countries around the world.Growing Campylobacter directly fixed media is an efficient method to Maqui Berry Review isolate this organism, but Campylobacter distinguish-Campylobacter microorganisms is difficult because different bacteria often look very similar.

Seung-Chul Yoon the Agency's assessment of the quality and safety Research Unit, Athens, GA., led the research team developed imaging technology is capable of detecting Campylobacter colonies fixed media 24 hours.Isolation and identification of Campylobacter food such as raw chicken-identification, as a general rule, slow or complex laboratory tests, that could take a few days a week.
This "sensor" technology, which was close to 100% with pure cultures typical wilting should be accurate, micro-organisms could be used for the early detection of outbreaks of different cultures loose Campylobacter. loose the scientists towards developing a screening technique to detect salmonella and Campylobacter food samples.
ARS research with other team members, the Director Kurt Lawrence, agricultural engineer Bosoon Park, animal physiologist William Windham and food technologists John Line and Peggy Feldner. line is ARS Poultry microbiological safety Research unit, also in Athens. Gregory Siragusa Danisco, Riitta, Bryggare, also made in the investigation.
The results of this study was published in the journal Sensing and instrumentation for food quality and safety. this study supports the priority of THE USDA Food safety.
