Good Morning! Highlights of today’s digest include a skin microbiome study in leprosy disease in Indian patients, another study shows findings from a mouse model and suggests vitamin B6 may have a therapeutic potential for treatment of chronic stress-induced gastritis. Finally, metagenomic sequencing and assembly of bacteria from different soils show how a soil type can influence genetic potential of bacteria for production of specialized metabolites such as antibiotics.
