3 days ago · Escherichia coli ( / ˌɛʃəˈrɪkiə ˈkoʊlaɪ / ESH-ə-RIK-ee-ə KOH-ly) [1] [2] is a gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms. [3] [4] Most E. coli strains are harmless, but some serotypes such as EPEC, and ETEC are ...
Apr 22, 2024 · E. coli strains, posing risks not only to animals but also to humans along the food chain [24,25]. A study examining ESBL-producing E. coli in sheep and goats revealed antimicrobial resistance patterns in both healthy and diarrheic animals [26]. Furthermore, there are reports of some strains potentially capable of producing Shiga toxin and carrying
Apr 26, 2024 · This study investigated the bactericidal effects of ultraviolet (UV) radiation, a high-voltage electric field (HVEF), and their combination on Escherichia coli. The results indicated that UV and combined disinfection were more effective with longer exposure, leading to significant reductions in microbial activity. Specifically, the single UV disinfection alone reduced activity by 3.3 log after ...
Apr 28, 2024 · Hydroponic cultivation of lettuce is an increasingly popular sustainable agricultural technique. However, Escherichia coli, a prevalent bacterium, poses significant concerns for the quality and safety of hydroponically grown lettuce. This study aimed to develop a growth model for E. coli and background microflora in hydroponically grown lettuce. The experiment involved inoculating ...
May 3, 2024 · l-Phenylalanine (l-Phe) is widely used in the food and pharmaceutical industries. However, the biosynthesis of l-Phe using Escherichia coli remains challenging due to its lower tolerance to high concentration of l-Phe. In this study, to efficiently synthesize l-Phe, the l-Phe biosynthetic pathway was reconstructed by expressing the heterologous genes aroK1, aroL1, and pheA1, along with the ...
Apr 30, 2024 · E. coli, ( Escherichia coli ), species of bacterium that normally inhabits the stomach and intestines. When E. coli is consumed in contaminated water, milk, or food or is transmitted through the bite of a fly or other insect, it can cause gastrointestinal illness. Mutations can lead to strains that cause diarrhea by giving off toxins, invading ...
May 7, 2024 · Published May 7, 2024 Updated May 8, 2024. Last week, federal officials announced recalls of ground beef and organic walnuts because they were potentially contaminated with E. coli bacteria that ...
