Antibiotic resistance, prompted by the overuse of antimicrobial agents, may arise from a
variety of mechanisms, particularly horizontal gene transfer of virulence and antibiotic …

Transformation is a widespread mechanism of horizontal gene transfer in bacteria. DNA
uptake to the periplasmic compartment requires a DNA-uptake pilus and the DNA-binding …

The human pathogens Streptococcus pneumoniae and Streptococcus mutans have both
evolved complex quorum sensing (QS) systems that regulate the production of bacteriocins …

A precise understanding of the genomic organization into transcriptional units and their
regulation is essential for our comprehension of opportunistic human pathogens and how …

Streptococcus pneumoniae becomes competent for genetic transformation when exposed to
an autoinducer peptide known as competence-stimulating peptide (CSP). This peptide was …

Natural competence enables bacteria to take up exogenous DNA. The evolutionary function
of natural competence remains controversial, as imported DNA can act as a source of …

This commentary was aimed at shedding light on the multifunction of bacteriocins mainly
those produced by lactic acid bacteria. These antibacterial agents were first used to improve …

Streptococcus pneumoniae is an opportunistic human pathogen that typically colonizes the
nasopharyngeal passage and causes lethal disease in other host niches, such as the lung …

It is currently well established that multicellular organisms live in tight association with
complex communities of microorganisms including a large number of bacteria. These are …

Streptococcus pneumoniae is a human pathobiont possessing a diverse array of
multifunctional proteins essential for bacterial fitness and virulence. Gene expression is …
