Clostridium difficile. A review on an emerging infection

Area of Science:

• Microbiology
• Infectious Diseases
• Gastroenterology

Background:

• Clostridium difficile causes significant healthcare-associated infections, including antibiotic-associated diarrhea and pseudomembranous colitis.
• Virulence factors include toxins A (TcdA), B (TcdB), and increasingly detected binary toxin (CDT).
• Clostridium difficile infection (CDI) is a major cause of morbidity and mortality in hospitalized older adults.

Purpose of the Study:

• To provide general recommendations for testing samples from patients with suspected Clostridium difficile infection (CDI).
• To emphasize the importance of timely laboratory diagnosis for effective treatment and prevention of CDI transmission.

Main Methods:

• Review of current diagnostic approaches for Clostridium difficile infection (CDI).
• Discussion of clinical history, laboratory tests, and the significance of detecting toxigenic strains.
• Focus on sample testing protocols for suspected CDI.

Main Results:

• Diagnosis of CDI is often difficult, relying on clinical history and laboratory tests.
• Timely laboratory diagnosis is crucial for identifying toxigenic strains.
• Effective and immediate treatment and prevention of disease transmission depend on accurate diagnosis.

Conclusions:

• Accurate and timely diagnosis of Clostridium difficile infection (CDI) is essential for patient management.
• Laboratory testing plays a critical role in detecting toxigenic strains and guiding treatment.
• Recommendations for sample testing are provided to improve CDI diagnosis and control.
