Insights

Streptococcus tigurinus, a novel bacterium, can cause severe infections. Its presence in the mouth, even with periodontal disease, suggests a potential link between oral health and systemic Streptococcus tigurinus infections.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Oral Health

Background:

  • Streptococcus tigurinus is a newly identified species within the viridans streptococci group.
  • It is closely related to other bacteria in the Streptococcus mitis group, including Streptococcus pneumoniae.
  • This bacterium has been detected in the human oral cavity, particularly in individuals with periodontal disease.

Purpose of the Study:

  • To review current scientific knowledge on Streptococcus tigurinus.
  • To explore its relationship with closely related streptococcal species.
  • To discuss the potential role of Streptococcus tigurinus in oral infections.

Main Methods:

  • Literature review of existing scientific studies on Streptococcus tigurinus.
  • Comparative analysis of Streptococcus tigurinus with related species in the Streptococcus mitis group.
  • Assessment of evidence linking Streptococcus tigurinus to oral and systemic infections.

Main Results:

  • Streptococcus tigurinus is associated with severe invasive infections like endocarditis, spondylodiscitis, and meningitis.
  • While found in the oral cavity, direct strong evidence linking it to common oral infections is currently lacking.
  • Its association with endocarditis highlights a potential connection between oral bacteria and systemic disease.

Conclusions:

  • Streptococcus tigurinus represents a significant pathogen capable of causing severe invasive diseases.
  • Further research is needed to fully understand the role of Streptococcus tigurinus in oral health and its contribution to systemic infections.
  • The presence of Streptococcus tigurinus in the oral cavity warrants attention due to its association with serious infections such as endocarditis.

The Oral Microbiota01:27

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Bacterial Phylum Spirochaetes01:30

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

Colonisation of Pathogens01:25

Colonisation of Pathogens

Pathogen colonization of host tissues is a critical step in the development of infectious diseases. Various pathogenic microorganisms, including bacteria, fungi, viruses, and protozoa, have evolved complex strategies to attach to, invade, and persist within host environments. These mechanisms enable pathogens to establish infections, evade immune responses, and resist antimicrobial treatments.Attachment to Host CellsIn bacteria, colonization typically begins with adherence to host epithelial...
