Conclusion
This report highlights the emergence of a resistant strain of Salmonella Enteritidis in Trinidad and Tobago, indicating a need for better surveillance of antimicrobial resistance.
Supporting Evidence
- S. Enteritidis caused 79 (66%) of 119 culture-confirmed salmonella infections in Trinidad in 1997.
- The isolate was resistant to all penicillins and cephalosporins, including third-generation cephalosporins.
- This is the first report of extended-spectrum beta-lactamase-mediated resistance among S. Enteritidis in the Caribbean.
Takeaway
Doctors found a type of Salmonella that doesn't respond to many antibiotics in a patient in Trinidad and Tobago, which is unusual and needs more attention.
Methodology
Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method.
Limitations
The study is based on a single case report and may not represent the broader population.
Participant Demographics
The patient was a 54-year-old male with multiple myeloma.
