Abstract
Bacillus cereus is a food contaminant and a known human pathogen that can cause emetic and diarrheal syndromes. In this study we evaluated the presence of toxigenic B. cereus by multiplex PCR directly in dietary complement for children and cassava starch samples collected on Medellin, Colombia. Of 75 dietary complement for children samples evaluated, 70.7% were contaminated with toxigenic B. cereus and four different toxigenic consortia were detected: I: nheA, hblC, cytK (9.8%), II: nheA, hblC (2%), III: hblC, cytK (41.2%), IV: hblC (47%). Of 75 cassava starch samples, 44% were contaminated with toxigenic B. cereus and four different toxigenic consortia were det...
