The term group A Streptococcus is considered synonymous for the species Streptococcus pyogenes. We describe an emergent invasive S. dysgalactiae subspecies equisimilis lineage that obtained the group A antigen through a single ancestral recombination event between a group C S. dysgalactiae subsp. equisimilis strain and group A S. pyogenes strain.

Name: Emerging infectious diseases
Severe infections due to Streptococcus dysgalactiae subsp. equisimilis (SDSE) have been identified in adults and may cause toxic shock syndrome, although with a low frequency.
Streptococcus dysgalactiae is an important pathogenic bacterium that has caused economic loss for the cobia industry in Taiwan, ROC. This study presents a highly effective subunit vaccine composed of ...
Invasive group B Streptococcus (GBS) remains a leading cause of illness and death among infants globally. We conducted prospective and retrospective laboratory-based surveillance of GBS-positive cultu...
Using population-based surveillance data, we quantified secondary invasive group A Streptococcus (iGAS) disease risk among household contacts. Disease risk in the 30 days post-exposure to an index cas...
Group B Streptococcus (GBS) is the leading cause of neonatal sepsis and meningitis worldwide. We aimed to estimate the current burden of neonatal invasive GBS disease in the Netherlands, as a first st...
Feasibility phase for a study to evaluate antibody levels against Group B Streptococcus in mothers and their infants at delivery to establish antibody levels associated with reductions in ...
This study will evaluate the safety and immunogenicity of a Group B Streptococcus vaccine.
The study is aimed at assessing pharyngeal and nasopharyngeal Streptococcus pneumonia carriage and pharyngeal Group A streptococcus carriage among field units new recruits.
Streptococcus pseudopneumoniae as suggested by DNA-DNA homology studies is recorded as a species of the Streptococcus mitis/oralis members of viridans group Streptococci; they have some si...
Part A: The primary objective is to evaluate the safety and tolerability of a potential vaccine against Group B streptococcus. Part B: To evaluate the long term safety profile of the GBS-...
A large heterogeneous group of mostly alpha-hemolytic streptococci. They colonize the respiratory tract at birth and generally have a low degree of pathogenicity. This group of species includes STREPTOCOCCUS MITIS; STREPTOCOCCUS MUTANS; STREPTOCOCCUS ORALIS; STREPTOCOCCUS SANGUIS; STREPTOCOCCUS SOBRINUS; and the STREPTOCOCCUS MILLERI GROUP. The latter are often beta-hemolytic and commonly produce invasive pyogenic infections including brain and abdominal abscesses.
A species of gram-positive bacteria in the STREPTOCOCCUS MILLERI GROUP. It is the most frequently seen isolate of that group, has a proclivity for abscess formation, and is most often isolated from the blood, gastrointestinal, and urogenital tract.
A species of gram-positive bacteria in the STREPTOCOCCUS MILLERI GROUP. It is commonly found in the oropharnyx flora and has a proclivity for abscess formation in the upper body and respiratory tract.
A species of gram-positive bacteria in the STREPTOCOCCUS MILLERI GROUP. It is commonly found in the oropharynx flora and has a proclivity for abscess formation, most characteristically in the CENTRAL NERVOUS SYSTEM and LIVER.
The type species of gram negative, aerobic bacteria in the genus ACHROMOBACTER. Previously in the genus ALCALIGENES, the classification and nomenclature of this species has been frequently emended. The two subspecies, Achromobacter xylosoxidans subsp. denitrificans and Achromobacter xylosoxidans subsp. xylosoxidans are associated with infections.
