Capsular exopolysaccharide, hyaluronic acid produced by Streptococcus equi subsp. zooepidemicus, carries high importance in pharmaceutical as well as biomedical field. In this direction, isolation and screening for exopolysaccharide producing streptococcus from nasopharynx of horses from Maharashtra and its neighbouring place was carried out. Out of 70 samples, none was observed to be Streptoco...

Necrotizing fasciitis (NF) is a severe soft tissue infection, characterized by rapid and fulminant progression. Thus, early suspicion, prompt medical aggressive surgical management are important for the clinical outcomes of NF. Despite rarity NF in infants group B streptococcus as its cause, 2-month-old preterm girl presented with involving suprapubic, inguinal, lower lateral abdominal regions ...

Streptococcus tigurinus is a novel species of viridans streptococci, shown to cause severe invasive infections such as infective endocarditis, spondylodiscitis and meningitis. S. tigurinus belongs to the Streptococcus mitis group and is most closely related to Streptococcus mitis, Streptococcus oralis, Streptococcus pneumoniae, Streptococcus pseudopneumoniae and Streptococcus infantis. The pres...

BACKGROUND AND AIM: In recent years, propolis has been introduced as one the most efficient agents against cariogenic bacteria. However, due to the lack of data on the propolis collected from Kandovan (Easthern Azarbaijan, Iran), this study was designed to investigate the effect of this type of propolis on Streptococcus mutans (S. mutans).METHODS: In this experimental study, the ethanolic extra...

BACKGROUND Population analysis of viridans streptococci is important because these species are associated with dental caries, bacteremia, and subacute endocarditis, in addition to being important members of the human oral commensal microbiota. DESIGN In this study, we phylogenetically analyzed the rod shape-determining protein gene (rodA), which is associated with cellular morphology, cell di...
