Leclercia adecarboxylata isolation: case reports and review

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Bacteriology

Background:

• Leclercia adecarboxylata is typically found in mixed bacterial cultures.
• While usually susceptible to antibiotics, resistant strains have been documented.
• In immunocompromised individuals, it may present as a pure culture infection.

Observation:

• This report details two distinct cases of L. adecarboxylata isolated in pure culture from immunocompetent patients.
• The first case involved isolation from a vaginal swab specimen.
• The second case involved isolation from a gluteal abscess.

Findings:

• Both L. adecarboxylata isolates from the presented cases were identified in pure cultures.
• The clinical presentations were diverse, originating from a gynecological source and a deep-seated abscess.
• Antimicrobial susceptibility testing revealed that both isolates remained sensitive to a broad range of commonly used antibiotics.

Implications:

• These cases highlight that L. adecarboxylata can cause infections in pure culture even in immunocompetent hosts.
• The findings suggest that while antibiotic resistance is a concern, L. adecarboxylata may remain susceptible to standard treatments in certain clinical scenarios.
• Further research into the pathogenic potential and optimal treatment strategies for L. adecarboxylata is warranted.
