Mechanisms of G-gene heterogeneities and a new method of genotyping of human metapneumovirus

The paper analyzes G-gene heterogeneities in human metapneumovirus (HMPV) and proposes a new genotyping method based on protein length and sequence differences.

Suregada multiflora Root Fluro-PolyPhosphate-Glycoside (NU2) inhibits MDR Bacteria and Unicellular Parasites Targeting DNA Topoisomerase I

This paper identifies NU2, a fluoropolyphosphate glycoside from Suregada multiflora roots, as an inhibitor of DNA topoisomerase I in MDR bacteria and parasites.

Four chromosomally clustered class-C β-lactamases (blaAmpH1/2/3/4) control the cephalosporin hydrolysis in Mycobacterium tuberculosis and similar genetic loci appeared as pseudogenes in Mycobacterium leprae

The paper identifies four chromosomally clustered class-C β-lactamases (blaAmpH1/2/3/4) in Mycobacterium tuberculosis responsible for cephalosporin hydrolysis, while these genes are pseudogenes in M. leprae.

Roles of Vitamin Metabolizing Genes in Multidrug-Resistant Plasmids of Superbugs

The paper identifies vitamin metabolizing genes in multidrug-resistant plasmids of superbugs and highlights their potential role in antibiotic resistance.
