Abstract
The contamination found in flexible gastrointestinal endoscopes was characterized at each step of reprocessing, by measuring: Adenosine Tri-Phosphate (ATP), colony forming units (CFUs), protein, and blood. Bacterial species isolated from culture positive scopes were identified.
Highlights
The contamination found in flexible gastrointestinal endoscopes was characterized at each step of reprocessing, by measuring: Adenosine Tri-Phosphate (ATP), colony forming units (CFUs), protein, and blood
The Log reductions in ATP contamination were found to be significant for each reprocessing step, whereas for CFUs the only significant reduction is after high level disinfection (HLD). 11% of the gastroscopes were culture positive after HLD
Levels of ATP, CFUs, protein and blood found in patientused endoscopes showed different reductions by type of endoscope and reprocessing step
Summary
The contamination found in flexible gastrointestinal endoscopes was characterized at each step of reprocessing, by measuring: Adenosine Tri-Phosphate (ATP), colony forming units (CFUs), protein, and blood.
