Conclusion
There was no clear trend in antibiotic resistance for Salmonella Virchow in Switzerland from 2004 to 2009, but the situation aligns with findings in other European countries.
Supporting Evidence
- The annual incidence of S. Virchow ranged from 0.45 to 0.40 cases per 100,000 from 2004 to 2009.
- 32% of strains were resistant to one to three antimicrobials, and 36% displayed resistance to more than three antibiotics.
- 62% of strains were resistant to nalidixic acid, indicating a high rate of decreased fluoroquinolone susceptibility.
Takeaway
This study looked at Salmonella infections in Switzerland and found that many strains were resistant to antibiotics, but the situation didn't change much over the years.
Methodology
The study characterized 153 Salmonella Virchow strains by assessing antibiotic resistance profiles and genotyping using pulsed-field gel electrophoresis.
Limitations
The study did not perform a case-control study and lacked detailed travel destination data for many patients.
Participant Demographics
The majority of strains were from patients aged 15 to 65 years, with 52% female and 48% male.
