Hypothesis
What is the prevalence and antimicrobial susceptibility pattern of MRSA isolates in Trinidad and Tobago?
Conclusion
The prevalence of MRSA in Trinidad and Tobago is 12.8%, which is low compared to other countries, and vancomycin remains effective against these infections.
Supporting Evidence
- 12.8% of Staphylococcus aureus isolates were methicillin resistant.
- Most MRSA isolates were found in wound swabs and surgical facilities.
- All MRSA isolates were resistant to ceftriaxone, erythromycin, gentamicin, and penicillin.
- MRSA isolates were 100% sensitive to vancomycin, rifampin, and chloramphenicol.
Takeaway
This study found that 12.8% of Staphylococcus aureus samples from hospitals in Trinidad and Tobago were resistant to methicillin, but vancomycin still works against them.
Methodology
The study analyzed Staphylococcus aureus isolates from clinical specimens in three major hospitals over two years, using standard laboratory identification and susceptibility testing methods.
Limitations
The study did not identify specific risk factors associated with MRSA infections.
Participant Demographics
The study included isolates from both male and female patients, with no significant gender differences in MRSA prevalence.
