To report a case of catheter-associated bloodstream infection caused by multidrug-resistant L. adecarboxylata in a colon tumor patient, highlighting its clinical significance.
Key Findings:
L. adecarboxylata was isolated from both peripheral blood and the central venous catheter, indicating a serious infection risk.
The patient was treated successfully with meropenem after initial cefoperazone-sulbactam failure, underscoring the importance of appropriate antibiotic selection.
Multidrug-resistant strains of L. adecarboxylata can occur, particularly in immunocompromised patients, necessitating vigilance in treatment.
Interpretation:
The case highlights the potential for multidrug-resistant L. adecarboxylata to cause serious infections in patients with risk factors such as malignancy and catheter use, suggesting a need for updated treatment guidelines.
Limitations:
This is a single case study, limiting generalizability and potential biases in case reporting.
Lack of extensive antimicrobial susceptibility data for L. adecarboxylata may hinder understanding of resistance patterns.
Conclusion:
Treatment of L. adecarboxylata infections should be guided by antimicrobial sensitivity tests, with an emphasis on ongoing surveillance of resistance patterns.
