چکیده

We have developed a paper-based analytical device as a platform for colorimetric detection of pathogenic bacteria responsible for foodborne illness. The food industry currently relies on time-consuming and complex analysis techniques to determine the presence of live Escherichia coli, Listeria monocytogenes, and Salmonella enterica in food products. Advantages of the paper-based design include low cost, simple fabrication and operation, portability, and disposability. Additionally, colorimetric assays allow for simple, rapid analysis. Using this novel method, enrichment time is reduced to 6 hr or less, with limits of detection on the order of 10 cfu/mL (colony forming units).

Detection of Colicin genes by PCR in Escherichia coli isolated from cattle in Shiraz-Iran

A variety of probiotic bacteria have been tested to control animal and foodborne pathogenic bacteria in livestock. The mechanism of inhibition of pathogenic bacteria for several of those probiotic microorganisms is mediated by the production of bacteriocins. Colicins are probably the group of bacteriocins that have been most thoroughly characterized. Colicins are antimicrobial proteins produced...
