Unrecognized threat in immunocompromised care: A case of Leclercia adecarboxylata bacteremia associated with long-term indwelling urinary catheter

Abstract

Leclercia adecarboxylata, a rare facultative gram-negative bacillus, is increasingly being recognized as an opportunistic pathogen, especially in immunocompromised hosts or those with indwelling devices. We report a case of L. adecarboxylata bacteremia in a 68-year-old diabetic male with a long-term Foley catheter. The patient presented with fever and confusion. Laboratory analysis revealed bacteremia and pyuria. Both blood and urine cultures isolated L. adecarboxylata, confirmed via MALDI-TOF MS. Treatment involved catheter removal and targeted ceftriaxone therapy based on susceptibility testing, resulting in clinical recovery. This case reinforces the organism’s pathogenic potential and highlights the importance of accurate identification and early intervention.
