ABSTRACT

Stool samples from 104 adult patients with nosocomial antibiotic–associated diarrhea were analyzed for Clostridium difficile by cultivation, toxin A inmunoenzymatic detection, and toxin B cytotoxic detection. The isolates were additionally screened for the toxin genes by polymerase chain reaction. C. difficile was isolated from 26 samples, and the toxins were directly detected in another 5 samples. Toxin A and B genes were detected in all toxigenic bacterial isolates. The detection rate of 30% indicates that C. difficile is a major etiologic agent of nosocomial diarrhea in Costa Rica.

Received December 28, 2007. Accepted for publication May 14, 2008.

Acknowledgments: The authors thank Dr. Nury Mora for helping to obtain samples, Pablo Vargas, Yorleny Alvarado, and Alexander Ramírez for technical assistance, and Dr Caterina Guzmán-Verri for collaboration with PCR techniques. The performed experiments complied with the current laws of Costa Rica.

Financial support: This research was supported by the Vicerrectoría de Investigación, Universidad de Costa Rica.
