Reviews of Infectious Diseases
|November 1, 1986
Summary
Cryptosporidium is a newly identified pathogen causing severe diarrhea in immunocompromised individuals and self-limited illness in others. Diagnosis is via stool acid-fast staining, but effective treatments remain elusive.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Parasitology
Background:
- Cryptosporidium is an emerging human pathogen.
- It causes severe enteritis and cholecystitis in immunocompromised individuals, especially those with acquired immunodeficiency syndrome (AIDS).
- It also causes self-limited diarrheal illness in immunocompetent hosts.
Purpose of the Study:
- To review the current understanding of Cryptosporidium as a human pathogen.
- To highlight diagnostic methods and the lack of effective therapies.
Main Methods:
- Review of existing literature on Cryptosporidium.
- Focus on clinical presentation, diagnosis, and treatment of cryptosporidiosis.
Main Results:
- Cryptosporidiosis is increasingly recognized worldwide, particularly in young children.
- Acid-fast staining of stool is an effective diagnostic tool.
- No consistently effective therapy for cryptosporidial infection is currently available.
Conclusions:
- Cryptosporidium is a significant cause of human diarrhea globally.
- Further research is needed to understand pathogenic mechanisms and host defense.
- Development of effective treatments for cryptosporidiosis is a critical unmet need.
