In the last few years matrix assisted laser desorption/ionization time-of-flight mass
spectrometry (MALDI-TOF MS) has been increasingly studied and applied for the …

Streptococcus mitis is a viridans streptococcus and a normal commensal of the human
oropharynx. However, S. mitis can escape from this niche and cause a variety of infectious …

The Human Microbiome Project provided a census of bacterial populations in healthy
individuals, but an understanding of the biomedical significance of this census has been …

Bacterial populations often consist of multiple co-circulating lineages. Determining how such
population structures arise requires understanding what drives bacterial diversification …

Alterations in the target enzymes for β-lactam antibiotics, the penicillin-binding proteins
(PBPs), have been recognized as a major resistance mechanism in Streptococcus …

The invention of MALDI‐TOF‐MS enormously contributed to the understanding of protein
chemistry and cell biology. Without this technique proteomics would most likely not be the …

The genetically diverse viridans group streptococci (VGS) are increasingly recognized as
the cause of a variety of human diseases. We used a recently developed multilocus …

Infections induced by oral biofilms include caries, as well as periodontal, and peri-implant
disease, and may influence quality of life, systemic health, and expenditure. As bacterial …

Extrachromosomal elements are ubiquitous in the prokaryotic world and play important roles
in the adaptation and survival of cell populations, especially in changing environments …

The bacterium Streptococcus pneumoniae is one of the leading causes of fatal infections
affecting humans. Intriguingly, phylogenetic analysis shows that the species constitutes one …
