Clostridium difficile in general practice and community health

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Diagnostics

Background:

• Clostridium difficile (C. diff) is an opportunistic pathogen.
• Diarrheal illness is a common presentation in general practice and community health settings.
• Accurate identification of enteropathogens is crucial for effective patient management.

Purpose of the Study:

• To determine the isolation rate of Clostridium difficile in patients presenting with diarrhea.
• To assess the prevalence of C. diff and its cytotoxin in stool samples.
• To evaluate the role of C. diff as an enteropathogen in community-based healthcare.

Main Methods:

• Prospective investigation over 14 months.
• Stool sample analysis for C. diff isolation and cytotoxin detection.
• Comparison of C. diff detection rates across different patient groups and with other enteropathogens.

Main Results:

• C. diff or its cytotoxin was detected in 4.7% of 1882 patients.
• C. diff accounted for 30.3% of isolated enteropathogens, second only to Giardia lamblia.
• Isolation rates varied significantly (3.6% to 27.5%) between patient groups, with considerable variation in the correlation between stool culture and cytotoxin assay.

Conclusions:

• Clostridium difficile is a notable cause of diarrhea in patients attending general practice and community health centers.
• Laboratories should be vigilant for C. diff in diarrheal stool specimens.
• Adequate clinical history is essential for appropriate specimen processing and diagnosis of C. diff infection.
