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.

How Next-Gen Sequencing is Revolutionizing Infection Diagnosis

Scientists from Necker-Enfants Malades Hospital (AP-HP), the Institut Pasteur, Université Paris Cité, Inserm, Université Paris-Est Créteil and the Alfort National Veterinary School, coordinated by Professor Marc Eloit and Dr. Anne Jamet in collaboration with Dr. Jacques Fourgeaud and Beatrice Regnault, studied the role of global genetic characterization of samples (or non-targeted metagenomics) using next-generation sequencing (mNGS) in diagnosing infections.

‘Smart’ food packaging material kills microbes and keeps food fresh

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.
