# Leclercia adecarboxylata in a Patient With Newly Diagnosed Chronic Lymphocytic Leukemia

## TL;DR

This paper reports a case of Leclercia adecarboxylata infection in a man with leukemia, highlighting its misdiagnosis and low virulence.

## Contribution

The novelty lies in documenting a rare clinical case of L. adecarboxylata bacteremia in an immunocompromised patient.

## Key findings

- L. adecarboxylata was identified in a 53-year-old immunocompromised male with chronic lymphocytic leukemia.
- The infection was successfully managed with antibiotics and did not result in severe complications.
- The case emphasizes the importance of accurate identification to avoid misdiagnosis as Escherichia coli.

## Abstract

Leclercia adecarboxylata is a Gram-negative bacillus commonly seen in immunocompromised individuals and often misdiagnosed as Escherichia coli. L. adecarboxylata is an opportunistic pathogen found in aquatic environments. It is a nonfatal infection that has low virulence and endorses susceptibility to many common antibiotics. We report a case of a 53-year-old immunocompromised male who was managed for L. adecarboxylata bacteremia.
