Genotyping Streptococcus Pneumoniae [PDF]

Future Microbiology, 2015
Streptococcus pneumoniae is a potentially deadly human pathogen associated with high morbidity, mortality and global economic burden. The universally used bacterial genotyping methods are multilocus sequence typing and pulsed field gel electrophoresis.

The pneumococcal response to oxidative stress includes a role for Rgg [PDF]

, 2009
Streptococcus pneumoniae resides in the oxygen-rich environment of the upper respiratory tract, and therefore the ability to survive in the presence of oxygen is an important aspect of its in vivo survival. To investigate how S.

Deletion of the Zinc Transporter Lipoprotein AdcAII Causes Hyperencapsulation of Streptococcus pneumoniae Associated with Distinct Alleles of the Type I Restriction-Modification System. [PDF]

, 2020
The capsule is the dominant Streptococcus pneumoniae virulence factor, yet how variation in capsule thickness is regulated is poorly understood. Here, we describe an unexpected relationship between mutation of adcAII, which encodes a zinc uptake ...

Streptococcus pneumoniae Capsular Polysaccharide

Microbiology spectrum, 2019
The polysaccharide capsule of Streptococcus pneumoniae is the dominant surface structure of the organism and plays a critical role in virulence, principally by interfering with host opsonophagocytic clearance mechanisms.

Streptococcus pneumoniae: Invasion and Inflammation

Microbiology spectrum, 2019
Streptococcus pneumoniae (the pneumoccus) is the leading cause of otitis media, community-acquired pneumonia, and bacterial meningitis. The success of the pneumococcus stems from its ability to persist in the population as a commensal and avoid killing ...

Streptococcus pneumoniae’s Virulence and Host Immunity: Aging, Diagnostics, and Prevention

Frontiers in Immunology, 2018
Streptococcus pneumoniae is an infectious pathogen responsible for millions of deaths worldwide. Diseases caused by this bacterium are classified as pneumococcal diseases. This pathogen colonizes the nasopharynx of its host asymptomatically, but overtime

Optimization of Loop-Mediated Isothermal Amplification Reaction for Detecting Streptococcus pneumoniae Serotypes in Clinical Nasopharynx Swab Samples [PDF]

E3S Web of Conferences
Current molecular PCR-based methods for identifying Streptococcus pneumoniae, the primary cause of pneumonia, meningitis, and other invasive diseases, are accurate but require expensive infrastructure and have a long run time, which restricts their use ...

Mechanisms of Naturally Acquired Immunity to Streptococcus pneumoniae

Frontiers in Immunology, 2019
In this review we give an update on the mechanisms of naturally acquired immunity against Streptococcus pneumoniae, one of the major human bacterial pathogens that is a common cause of pneumonia, septicaemia, and meningitis.

Competence in Streptococcus pneumoniae and Close Commensal Relatives: Mechanisms and Implications

Frontiers in Cellular and Infection Microbiology, 2019
The mitis group of streptococci comprises species that are common colonizers of the naso-oral-pharyngeal tract of humans. Streptococcus pneumoniae and Streptococcus mitis are close relatives and share ~60–80% of orthologous genes, but still present ...
