Study Findings on Salmonellosis Are Outlined in Reports from Yeungnam University (Immunochromatographic strip assay for the rapid and sensitive detection of Salmonella Typhimurium in artificially contaminated tomato samples)
By a News Reporter-Staff News Editor at Health & Medicine Week -- Fresh data on Salmonellosis are presented in a new report. According to news originating from Gyongsan, South Korea, by NewsRx correspondents, research stated, "This study was designed to confirm the applicability of a liposome-based immunochromatographic assay for the rapid detection of Salmonella enterica subsp. enterica serovar Typhimurium (Salmonella Typhimurium) in artificially contaminated tomato samples. To determine the detection limit and pre-enrichment incubation time (10, 12, and 18 h pre-enrichment in 1% buffered peptone water), the tests were performed with different cell numbers of Salmonella Typhimurium (3 x 10(0), 3 x 10(1), 3 x 10(2), and 3 x 10(3) CFU.mL(-1)) inoculated into 25 g of crushed tomato samples."
Our news journalists obtained a quote from the research from Yeungnam University, "The assay was able to detect as few as 30 Salmonella Typhimurium cells per 25 g of tomato samples (1.2 cells.g(-1)) after 12 h pre-enrichment incubation. Moreover, when the developed assay was compared with traditional morphological and biochemical culture-based methods as well as colloidal gold nanoparticle-based commercial test strips, the developed assay yielded positive results for the detection of Salmonella Typhimurium within a shorter period time."
According to the news editors, the research concluded: "These findings confirm that the developed assay may have practical application for the sensitive detection of Salmonella Typhimurium in various food samples, including raw vegetables, with a relatively low detection limit and shorter analysis time."
