Pathways of genetic adaptation: multistep origin of mutants under selection without induced mutagenesis in Salmonella enterica. [PDF]
, 2012 In several bacterial systems, mutant cell populations plated on growth-restricting medium give rise to revertant colonies that accumulate over several days.

An orthologue of bacteroides fragilis NanH is the principal sialidase in tannerella forsythia [PDF]
, 2009 Sialidase activity is a putative virulence factor of the anaerobic periodontal pathogen Tannerella forsythia, but it is uncertain which genes encode this activity.

Oligosaccharides in Milk: Their Benefits and Future Utilization [PDF]
, 2010 The percentage of carbohydrate in the milk/colostrum of the mammalian is range from trace to over 10%, of which disaccharide lactose (Gal(β1-4)Glc) is usually constitutes the major part.

Protein-Mediated DNA Loops: Effects of Protein Bridge Size and Kinks
, 2005 This paper focuses on the probability that a portion of DNA closes on itself through thermal fluctuations. We investigate the dependence of this probability upon the size r of a protein bridge and/or the presence of a kink at half DNA length.

cDNA-RNA subtractive hybridization reveals increased expression of mycocerosic acid synthase in intracellular Mycobacterium bovis BCG. [PDF]
, 2001 Identifying genes that are differentially expressed by Mycobacterium bovis BCG after phagocytosis by macrophages will facilitate the understanding of the molecular mechanisms of host cell-intracellular pathogen interactions. To identify such genes a cDNA-

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.ABSTRACT Genetic features of host adaptation of S. aureus to ruminants have been extensively studied, but the extent to which this adaptation occurs in nature remains unknown. In New Zealand, clonal complex 1 (CC1) is among the most common lineages in humans and the dominant lineage in cattle, enabling between‐, and within‐CC genomic comparisons of ...

Controlled functional expression of the bacteriocins pediocin PA-1 and bactofencin A in Escherichia coli [PDF]
, 2017 peer-reviewedThe bacteriocins bactofencin A (class IId) and pediocin PA-1 (class IIa) are encoded by operons with a similarly clustered gene organization including a structural peptide, an immunity protein, an ABC transporter and accessory bacteriocin ...

Molecular Microbiology, Volume 123, Issue 5, Page 439-453, May 2025.The Roc system represents a highly interconnected but incomplete network of two‐component regulatory systems involved in the virulence of Pseudomonas aeruginosa. Our work has enabled us to identify the missing RocA3 regulator, to propose new players in the system and to delineate their conservation between clades of the species.

Microbial Biotechnology, Volume 18, Issue 4, April 2025.This study reveals the regulatory mechanism behind sugar metabolism and dextran synthesis by Leuconostoc pseudomesenteroides DSM20193 during the fermentation of a complex substrate like brewers spent grain. Understanding metabolic pathways and genetic adaptation of lactic acid bacteria in food environments can help develop fermented products with ...
