Background The skin microbiome is essential in guarding against harmful pathogens and
responding to environmental changes by generating substances useful in the cosmetic and …

Biochemical, molecular chemical and molecular genetic studies were performed on an
unknown Gram-positive, catalase-negative, chain-forming coccus isolated from the urine of …

The production of mannosidase activity by all currently recognized species of human
viridans group streptococci was determined using an assay in which bacterial growth was …

Bacterial IgA1 proteases share the ability to cleave human IgA1 at the hinge region. Nature
has developed this trait along at least five independent evolutionary lineages. To obtain …

Many streptococcal species belonging to the mitis and anginosus phylogenetic groups are
known to be naturally competent for genetic transformation. Induction of the competent state …

The pneumococcus (Streptococcus pneumoniae or diplococcus) has been profoundly
important in the understanding of the human response to infectious disease, the nature of …

Mitis group streptococci are pioneer colonizers of tooth surfaces and are implicated in
various pathologies. Thus, accurate identification of oral mitis group strains would be …

Serial revisions of the genus Streptococcus have been implemented since its genesis. The
designation “lactic” streptococci, although somewhat misleading since all streptococci …

Background Population analysis of viridans streptococci is important because these species
are associated with dental caries, bacteremia, and subacute endocarditis, in addition to …

Recently, the development of culture-independent molecular technologies such as next-
generation sequencing (NGS) has increased an attention to the research about gastric …
