Primary Institution: Universidad de Los Andes, Mérida, Venezuela
Hypothesis
Microorganisms with antibiotic resistance mechanisms can be present in patients in the community.
Conclusion
CTX-M-14 producing C. freundii is an emerging pathogen in community settings in Mérida, Venezuela.
Supporting Evidence
- This is the first report of CTX-M-14 in Venezuela.
- The isolate showed multidrug resistance but was susceptible to carbapenems.
- Conjugation experiments confirmed the transferability of resistance markers.
Takeaway
A woman in Venezuela had a urinary infection caused by a type of bacteria that is becoming resistant to many antibiotics. This is important because it shows that these resistant bacteria can spread in the community.
Methodology
The study involved isolating the bacteria from a urine sample, performing susceptibility tests, and confirming the presence of the blaCTX-M-14 gene through PCR and sequencing.
Limitations
The study is based on a single case report, which may not represent broader trends.
Participant Demographics
A 47-year-old woman with a history of recurrent urinary tract infections.
