Hypothesis
What is the genetic diversity of Salmonella enterica serovar Typhi in blood cultures and gallbladder specimens from patients in Makassar, Indonesia?
Conclusion
The study found a large diversity of Salmonella Typhi genotypes in blood cultures and identified a unique genotype in gallbladder specimens from cholelithiasis patients.
Supporting Evidence
- 297 Salmonella Typhi blood culture isolates were analyzed, revealing 76 distinct genotypes.
- Four unique S. Typhi isolates were found in gallbladder specimens from cholelithiasis patients.
- The majority of culture-positive patients had moderate disease conditions.
- Genotype EInd100 was not found in any blood culture isolates from typhoid patients.
Takeaway
Scientists studied bacteria that cause typhoid fever in Indonesia and found many different types, including one special type from patients with gallbladder issues.
Methodology
Multi-locus variable-number tandem repeat analysis was used to genotype Salmonella Typhi isolates from blood cultures and gallbladder specimens.
Limitations
The study did not assess the precise morphological location of infections in gallbladder patients and relied on culture methods that may miss some infections.
Participant Demographics
The study included 297 typhoid patients with a median age of 29 years, and four cholelithiasis patients aged 24 to 42 years.
