Abstract

OBJECTIVE.  To determine whether disinfection protocols currently used for gastroscopes are effective against cultures of Tropheryma whipplei. DESIGN.  The bactericidal activity of 2% glutaraldehyde and two peracetic acids on the Twist‐Marseille strain of T. whipplei grown in cell monolayers was determined. PATIENTS.  Two patients who were diagnosed as having Whipple’s disease 3 years after they had had intestinal biopsies. RESULTS.  The disinfectants reduced bacteria by approximately 2 log10 to 3 log10 after 5 to 60 minutes of contact. CONCLUSION.  The bactericidal activity of a disinfectant is usually considered significant if it causes a 5 log10 or greater reduction in viable bacterial titers. Disinfecting gastroscopes with 2% glutaraldehyde or peracetic acids for 20 minutes may be insufficient to prevent transmission of T. whipplei on the instruments or stop false‐positive results on polymerase chain reaction.
