New Study Challenges Prevailing Theories on Tuberculosis Bacteria Growth Introduction Tuberculosis (TB), a rod-shaped bacterium ranked by the World Health Organization as the world's deadliest infectious disease , has been revealed as the first single-celled organism ca pable of maintaining a constant growth rate throughout its entire life cycle. Groundbreaking Discovery Researchers at Tufts University School of Medicine share this groundbreaking discovery in the journal Nature Microbiology   on November 15, reshaping long-held views of bacterial cell biology and shedding light on the  pathogen's resilience against immune defenses and antibiotics. New Insights into TB Pathogen Behavior "The study of bacterial growth and division is one of the sim plest areas of research in microbiology, yet our findings show that the TB  pathogen o perates under an entirely unique set of  princi ples." ex plained Bree Aldridge, co-senior author and  professor at Tufts University...

Dietary Zinc as an Inhibitor of Antimicrobial Resistance Gene Transmission Research Findings from Iowa State University The Role of Dietary Zinc in Inhibiting AMR Plasmids Antimicrobial resistance (AMR) genes can spread among microbes via  plasmids, circular genetic elements, during lateral gene transfer in the gut, Iova researchers, in their re port in Applied and Environmental Microbiology , notes that dietary zinc su p plementation may inhibit the transmission of certain AMR  plasmids. Insights from Dr. Melha Mellata "This is the first instance where we have identified zinc as an inhibitor of  plasmid transfer, and at lower concentrations, it excerts minimal im pact on bacteria," stated Dr. Melha Mellata, microbiologist and senior author of the study at Iowa State University. Importance of Preventing Plasmid Transfer "This is im portant," she remarked, "because killing gut bacteria could lead to microbiome imbalances, with  possible negative health consequen...
