Abstract:
During a period of 26 months, 80 strains of Streptococcus milleri were isolated from 80 patients with clinical evidence of infection. More than a third of the isolates were from lesions related to the gastro-intestinal tract and a quarter from abscesses of various other sites. The haemolytic activity and group antigenic profile of these isolates are discussed. In addition, the clinical significance of S. milleri isolated from various sites is evaluated.
Insights
This study analyzed 80 Streptococcus milleri strains from infected patients. Most isolates came from gastro-intestinal infections and abscesses, highlighting their clinical significance.
Area of Science:
- Microbiology
- Infectious Diseases
Background:
- Streptococcus milleri group (SMG) bacteria are common commensals.
- SMG can cause various infections, but their epidemiology and clinical significance require further elucidation.
Purpose of the Study:
- To characterize Streptococcus milleri isolates from infected patients.
- To evaluate the clinical significance of S. milleri in different infection sites.
Main Methods:
- Prospective isolation of 80 Streptococcus milleri strains from 80 patients over 26 months.
- Analysis of isolate sources, including gastro-intestinal tract lesions and abscesses.
- Assessment of haemolytic activity and group antigenic profiles.
Main Results:
- Over a third of isolates originated from gastro-intestinal tract lesions.
- A quarter of isolates were recovered from abscesses at various body sites.
- Haemolytic activity and antigenic profiles were characterized for the isolates.
Conclusions:
- Streptococcus milleri is a significant pathogen in gastro-intestinal infections and abscesses.
- Understanding the characteristics of S. milleri isolates is crucial for effective clinical management.
- Further research into the pathogenicity of S. milleri is warranted.
