|January 1, 1989
Summary
This study analyzed urine samples from patients with suspected urinary tract infections (UTIs). Escherichia coli was the primary cause of community-acquired UTIs, while Streptococcus faecalis and E. coli were key in hospital-acquired infections.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Diagnostics
Background:
- Urinary tract infections (UTIs) are common, with varying etiological agents in community-acquired versus hospital-acquired cases.
- Understanding causative pathogens and their antimicrobial sensitivity is crucial for effective treatment.
Purpose of the Study:
- To isolate and identify bacterial flora in urine samples from patients with suspected UTIs.
- To evaluate the antimicrobial sensitivity of identified microorganisms.
- To compare the etiological agents of community-acquired UTIs with those in hospitalized patients.
Main Methods:
- Analysis of 651 urine samples (460 external, 191 hospitalized patients).
- Bacterial flora isolation and microorganism identification.
- Antimicrobial sensitivity testing.
Main Results:
- Identified 89 bacterial strains from external patients and 215 from hospitalized patients.
- Escherichia coli was the dominant pathogen (68.59%) in community-acquired UTIs.
- Streptococcus faecalis (18.61%) and E. coli (13.96%) were the main causative agents in hospitalized patients.
Conclusions:
- Etiological profiles of UTIs differ significantly between community and hospital settings.
- E. coli is a major pathogen in both settings, but other bacteria like S. faecalis are more prevalent in hospitalized patients.
- Antimicrobial sensitivity data is essential for guiding UTI treatment strategies.
