Inhibitory effects of sweeteners on bacterial quorum sensing

Scientists at Ben-Burion University in Israel discovered that some artificial sweeteners hurt the gut flora to quorum sensing. The study shows that aspartame, sucralose, and saccharin have significant inhibitory actions on the Gram-negative bacteria N-acyl homoserine lactone-based (AHL) communication system. The study concluded that artificial sweeteners disrupt communication, indicating that artificial sweeteners may be problematic in changing the microbiome and potentially increasing disease risk. Three less common sweeteners, acesulfame potassium (Ace-K), advantame, and neotame, did not have this effect.

Decreased incidence of infections caused by food pathogens during the 2020 COVID-19 Pandemic

FoodNet monitors laboratory-diagnosed infections caused by eight pathogens regularly transmitted through food (Campylobacter, Cyclospora, Listeria, Salmonella, Shiga toxin-producing Escherichia coli (STEC), Shigella, Vibrio, and Yersinia). Cases of infection cover 10 states (covering roughly 15% of the United States’ population). A new research was published in the CDC’s Morbidity and Mortality Weekly based on preliminary data from 2020 and issued by the Foodborne Diseases Active Surveillance Network (FoodNet). The study identified 26% fewer infections in 2020, compared with the average annual number during 2017–2019, including decreased infections associated with international travel. The decline was from 50 cases/100,000 during 2017-2019 to 37...

Cornell University scientists create a national atlas for Listeria monocytogenes collected from soils across the US

Cornell University Dr. Martin Wiedmann, Jingqiu Liao, and the team created an atlas of Listeria monocytogenes in US soils. The research was published in Nature Microbiology. The study developed a nationwide atlas of 1,854 Listeria isolates, collected systematically from soils across the United States.  The Cornell team found that Listeria was present in a variety of environments. Listeria presence was affected by soil moisture, molybdenum, and salinity concentrations. When scientists identify a Listeria, the atlas will inform them where the Listeria resides in the USA. Identifying the location can pinpoint the source of the organism found in ingredients processing facilities...

New research: Dog food sold across Europe contains antibiotic-resistant bacteria

New research presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) reveals that raw dog food is a significant source of antibiotic-resistant bacteria, making it an international public health risk. According to WHO, drug-resistant infections kill ~700,000 people/ year globally and, it is projected to rise to 10 million by 2050 if no action is taken. The researchers say that the trend of feeding dogs with raw food may be fuelling the spread of antibiotic-resistant bacteria. Some of the multidrug-resistant bacteria in raw dog food were identical to those found in hospital patients in several different European...
