Listeria News and Research

RSS

Listeria is a bacterial genus containing seven species. Named after the English pioneer of sterile surgery, Joseph Lister, Listeria species are Gram-positive bacilli and are typified by ''L. monocytogenes'', the causative agent of listeriosis.

Does breast milk influence infants' intestinal microbiota?

A large number of health-related benefits of probiotics have led to the development of a new discipline called probiogenomics, which focuses on the molecular mechanisms of probiotic activities. According to the US Food and Drug Administration (FDA), the next-generation probiotics satisfy the scope of "live biotherapeutic products" (LBPs), which could be used to develop effective therapeutics for various diseases.

New therapy makes immunologically 'cold' tumors hot enough for immune attack

Pancreatic cancer is notoriously difficult to cure or even treat. Now, a new strategy devised by scientists at Albert Einstein College of Medicine has succeeded in making pancreatic tumors visible to the immune systems of mice and vulnerable to immune attack, reducing cancer metastases by 87%.

Research reveals significant decrease in gastrointestinal infections during first 6 months of the pandemic

The number of reported gastrointestinal infection outbreaks more than halved during the first 6 months of the COVID-19 pandemic in the UK, compared with the previous 5-year average, while lab confirmed cases fell by a third, finds research published in the open access journal BMJ Open.

New biodegradable smart food packaging material helps kill harmful microbes

A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) and Harvard T.H. Chan School of Public Health, US, has developed a 'smart' food packaging material that is biodegradable, sustainable and kills microbes that are harmful to humans. It could also extend the shelf-life of fresh fruit by two to three days.
