Streptococcus oralis, a common oral bacterium, can cause severe infections like endocarditis and meningitis when it spreads to other body parts. This review updates knowledge on its pathogenic potential for better prevention and treatment.
Area of Science:
- Microbiology
- Infectious Diseases
- Oral Health
Background:
- Streptococcus oralis (S. oralis) is part of the normal oral flora (viridans group streptococci - VGS).
- Recent studies show S. oralis can translocate from the oral cavity to other body sites.
- This translocation can lead to severe opportunistic infections, including infective endocarditis (IE) and meningitis.
Purpose of the Study:
- To consolidate and update current knowledge on the pathogenic potential of S. oralis.
- To highlight the increasing risk of S. oralis-associated opportunistic infections.
- To provide a foundation for developing strategies for prevention and treatment.
Main Methods:
- This is a review article.
- Literature search and synthesis of existing research on S. oralis pathogenicity.
- Analysis of documented cases of S. oralis infections.
Main Results:
- S. oralis is an emerging opportunistic pathogen.
- Dental procedures and tooth brushing are identified as potential routes for S. oralis dissemination.
- Infective endocarditis and meningitis are significant clinical manifestations.
Conclusions:
- Understanding S. oralis pathogenicity is crucial for managing opportunistic infections.
- Further research is needed to elucidate specific virulence factors.
- Improved preventative measures and targeted treatments are required for S. oralis infections.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
