Direct PCR detection of Escherichia coli O157:H7 [PDF]
Letters in Applied Microbiology, 2003 This paper reports a simple, rapid approach for the detection of Shiga toxin (Stx)-producing Escherichia coli (STEC).Direct PCR (DPCR) obviates the need for the recovery of cells from the sample or DNA extraction prior to PCR. Primers specific for Stx-encoding genes stx1 and stx2 were used in DPCR for the detection of E.

Frontiers in Microbiology, 2018 Viable but non-culturable (VBNC) cells are alive bacteria cells, but lose their culturability in conventional culture media, usually escape detection by the plate count method and pose a serious threat to food safety and public health.

Food Frontiers, Volume 7, Issue 1, January 2026.ABSTRACT A substantial proportion of fresh fruit undergoes processing, resulting in underutilized fruit by‑products (FBPs) that are rich in dietary fiber and bioactive compounds. Recent FBP valorization trends demonstrate that fermentation significantly enhances microbiological, nutritional, and sensory attributes, yielding value‑added food supplements.

Experimental Escherichia coli O157:H7 carriage in calves [PDF]
Applied and Environmental Microbiology, 1997 Nine weaned calves (6 to 8 weeks of age) were given 10(10) CFU of a five-strain mixture of enterohemorrhagic Escherichia coli O157:H7 by oral-gastric intubation. After an initial brief period of pyrexia in three calves and transient mild diarrhea in five calves, calves were clinically normal throughout the 13- to 27-day study. The population of E. coli

Food Safety and Health, Volume 4, Issue 1, Page 50-66, January 2026.Laser‐induced breakdown spectroscopy (LIBS) emerges as a transformative tool for rapid, on‐site pesticide residue detection in food, offering real‐time screening with minimal sample preparation and eliminating solvent use. Although LIBS demonstrates detection limits (0.009–6.9 mg/kg) suitable for regulatory screening and aligns with green chemistry ...
