Disseminated infection caused by Emmonsia pasteuriana in a renal transplant recipient

Area of Science:

• Medical Mycology
• Infectious Diseases
• Transplant Medicine

Background:

• Emmonsia pasteuriana is a thermally dimorphic fungus rarely implicated in human infections.
• Renal transplant recipients are immunocompromised, increasing susceptibility to opportunistic infections.

Observation:

• A 43-year-old male renal transplant patient presented with painful skin lesions on the head, nose, and thigh.
• The patient subsequently developed respiratory failure.
• Histopathology revealed chronic inflammation, granuloma formation, and yeast-like elements in skin biopsies.

Findings:

• Emmonsia pasteuriana was successfully cultured and identified via rDNA internal transcribed spacer sequencing from biopsy specimens.
• The patient demonstrated marked clinical improvement following intensive care and antifungal therapy.

Implications:

• This case highlights E. pasteuriana as a potential pathogen in immunocompromised individuals, particularly transplant recipients.
• Early diagnosis and appropriate antifungal treatment are crucial for managing Emmonsia infections.
• Further research into the epidemiology and clinical spectrum of E. pasteuriana in humans is warranted.
