Insights

Streptococcus constellatus, a type of viridans Streptococcus, is linked to abscesses in children, particularly those with perforated appendicitis. This finding is relevant for pediatric infectious disease research.

Area of Science:

  • Microbiology
  • Pediatric Infectious Diseases
  • Clinical Bacteriology

Background:

  • Streptococcus constellatus is a member of the viridans Streptococcus group, specifically within the Anginosus group.
  • Viridans streptococci are known commensals but can be opportunistic pathogens.

Purpose of the Study:

  • To investigate the association between Streptococcus constellatus and abscess formation in pediatric patients.
  • To determine the clinical context, such as appendicitis, in which S. constellatus infections occur in children.

Main Methods:

  • Retrospective analysis of pediatric cases involving Streptococcus constellatus.
  • Review of clinical data, including diagnoses, surgical findings, and microbiological results.

Main Results:

  • Streptococcus constellatus was identified in abscesses in 37 pediatric patients.
  • A significant proportion (80%) of these children had acute appendicitis with perforation.
  • Abscess formation was noted in 50% of the appendicitis cases.
  • All affected children were 3 years of age or older.

Conclusions:

  • Streptococcus constellatus is implicated as a causative agent in pediatric abscesses.
  • The bacterium is frequently associated with complicated appendicitis, specifically perforation and subsequent abscess formation.
  • Clinical vigilance for S. constellatus is warranted in pediatric cases of appendicitis, especially in children aged 3 years and above.

Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

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...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
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...
