emm Types and Clusters of Group A Streptococcus Causing Acute Pharyngitis in Changwon Korea, 2018–2019

Annals of Clinical Microbiology, 2021
Background: Group A streptococcus (GAS) is the most common cause of bacterial pharyngitis. This study aimed to characterize the molecular epidemiology of GAS infection using an emmtyping and emm-clustering approach.

Conjugative transfer of ICESde3396 between three β-hemolytic streptococcal species [PDF]

, 2014
Background: Integrative conjugative elements (ICEs) are mobile genetic elements (MGEs) that possess all genes necessary for excision, transfer and integration into recipient genome. They also carry accessory genes that impart new phenotypic features to

Developing a serocorrelate of protection against invasive group B streptococcus disease in pregnant women: a feasibility study. [PDF]

, 2019
BACKGROUND: Group B streptococcus is the leading cause of infection in infants. Currently, intrapartum antibiotic prophylaxis is the major strategy to prevent invasive group B streptococcus disease.

Correlates of Protection for M Protein-Based Vaccines against Group A Streptococcus

Journal of Immunology Research, 2015
Group A streptococcus (GAS) is known to cause a broad spectrum of illness, from pharyngitis and impetigo, to autoimmune sequelae such as rheumatic heart disease, and invasive diseases.

Enhanced nasopharyngeal infection and shedding associated with an epidemic lineage of emm3 group A Streptococcus [PDF]

, 2017
Background: A group A Streptococcus (GAS) lineage of genotype emm3, sequence type 15 (ST15) was associated with a six month upsurge in invasive GAS disease in the UK.

GMMA as an Alternative Carrier for a Glycoconjugate Vaccine against Group A Streptococcus

Vaccines, 2022
Group A Streptococcus (GAS) causes about 500,000 annual deaths globally, and no vaccines are currently available. The Group A Carbohydrate (GAC), conserved across all GAS serotypes, conjugated to an appropriate carrier protein, represents a promising ...

Human streptococcus agalactiae strains in aquatic mammals and fish [PDF]

, 2013
<p>Background: In humans, Streptococcus agalactiae or group B streptococcus (GBS) is a frequent coloniser of the rectovaginal tract, a major cause of neonatal infectious disease and an emerging cause of disease in non-pregnant adults.

The development of a 16S rRNA gene based PCR for the identification of Streptococcus pneumoniae and comparison with four other species specific PCR assays [PDF]

, 2010
Background: Streptococcus pneumoniae is one of the most frequently encountered pathogens in humans but its differentiation from closely related but less pathogenic streptococci remains a challenge.

Streptococcus pyogenes and re-emergence of scarlet fever as a public health problem

Emerging Microbes and Infections, 2012
Explosive outbreaks of infectious diseases occasionally occur without immediately obvious epidemiological or microbiological explanations. Plague, cholera and Streptococcus pyogenes infection are some of the epidemic-prone bacterial infections.

Fibronectin-binding protein gene recombination and horizontal transfer between group A and G streptococci [PDF]

, 2004
We report evidence of interspecies gene transfer between the important virulence factor genes sfbI and gfbA. Because the identified group G streptococcus gfbA types possess DNA cassettes that can be identified in a number of group A streptococcus strains,
