Proteus penneri urosepsis in a patient with diabetes mellitus

Area of Science:

• Clinical microbiology
• Infectious diseases
• Urology

Background:

• Proteus penneri is a Gram-negative bacterium known to cause various infections.
• Nosocomial infections are hospital-acquired infections that pose a significant threat to patient safety.

Observation:

• A case of Proteus penneri nosocomial urosepsis was identified in a patient with diabetes.
• The bacterium was subsequently found in bronchoalveolar lavage fluid and on a pulmonary artery catheter tip.

Findings:

• This is the first reported instance of Proteus penneri causing nosocomial urosepsis in a diabetic individual.
• The findings indicate the potential for Proteus penneri to cause severe, disseminated infections in vulnerable patient populations.

Implications:

• Highlights the importance of recognizing Proteus penneri as a potential pathogen in nosocomial infections, especially in diabetic patients.
• Suggests the need for vigilance in diagnosing and managing Proteus penneri infections to prevent complications.
• Underscores the significance of source control and appropriate antimicrobial therapy in treating complex nosocomial infections.
