Parks, Ph.D., and Mindy M. Brashears, Ph.D. Shiga toxin-producing Escherichia coli (STEC) are pathogens of concern across various products within the food industry, as they have been connected to a wide variety of outbreaks and recalls. Most of the scientific literature concerning the removal of attached STEC cells focuses on E. coli O157:H7, as it was the first STEC to be considered an adulterant in nonintact beef products in the United States after a large outbreak from undercooked ground beef patties in 1982.[1] Worldwide, non-O157 STEC strains are estimated to cause 20 to 50 percent of STEC-related infections.[2] A review of outbreaks from 1983 through 2002 found six serogroups (O26, O111, O103, O121, O145 and O45) to be the most common non-O157 STECs causing human illness in the United States.[3] With an estimated 70 percent of non-O157 STEC infections being caused by these serogroups, the U.S.

Detergent/Sanitizer Combination Effectiveness. BMC - 2015 - Inactivation of Escherichia coli O157:H7and Listeria monocytogenes in biofilms by pulsed ultraviolet light. The contamination and persistence of pathogenic bacteria in certain fresh produce, including ready-to-eat products, have become an emerging concern in recent years.

Minimally processed, ready-to-eat fruits and vegetables may contain human pathogens among their microflora owing to contamination at some point in the process from cultivation to consumption. Microbial contamination of fruits and vegetables may occur on the surface or may become internalized through cuts or crevices on the produce [1].

Nanotechnology Now - Press Release: "Researchers control adhesion of E. coli bacteria" Home > Press > Researchers control adhesion of E. coli bacteria Abstract: A research team from Kiel University (CAU) and Goethe University Frankfurt have jointly created a synthetic surface on which the adhesion of E. coli bacteria can be controlled.

The layer, which is only approximately four nanometres thick, imitates the saccharide coating (glycocalyx) of cells onto which the bacteria adhere such as during an infection. This docking process can be switched on and off using light. This means that the scientists have now made an important step towards understanding the relationship between sugar (carbohydrates) and bacterial infections. Appl. Environ. Microbiol.

Appl. Environ. Microbiol. January 2005 Biofilm Formation by Escherichia coli O157:H7 on Stainless Steel: Effect of Exopolysaccharide and Curli Production on Its Resistance to Chlorine

Shown in Fig. 1 are populations of planktonic cells of E. coli O157:H7 strains 43895-EPS, ATCC 43895-, and ATCC 43895+ grown on HLJA at 22 and 12°C and treated with chlorine (10, 25, and 50 μg/ml) for 1, 3, 5, and 10 min. Cell suspensions contained various amounts of ECC (Table 1), depending on strain and growth conditions. Strain 43895-EPS was more resistant than strains ATCC 43895- and ATCC 43895+ to chlorine, indicating that protection was afforded by ECC. The population of strain 43895-EPS grown at 22°C decreased by 5.2 log10 CFU/ml when treated for 10 min with 10 μg of chlorine/ml, but cells grown at 12°C were unaffected by the same treatment.

Plutôt que d'être repoussées par des surfaces nanostructurées, comme des scientifiques des matériaux l’avaient espéré, les bactéries avec des nombreux flagelles semblent en fait beaucoup les aimer. (Image au microscope électronique à balayage, en fausses couleurs avec la permission de Ronn Friedlander et Michael Bucaro). Une nouvelle étude de l'Université Harvard contribue à expliquer comment des bactéries d'origine hydrique peuvent coloniser des surfaces rugueuses, même celles qui ont été conçues pour résister à l'eau.

Une équipe de scientifiques des matériaux et des microbiologistes ont étudié une bactérie, Escherichia coli, qui a de nombreux flagelles qui se fixent dans toutes les directions. Articles similaires.
