[Contamination of bronchial fiberscopes by mycobacteria. Myth or reality?].
The authors report the results of a study into mycobacterial contamination of bronchial fibroscopes over a 6 year period during which 8,750 fibroscopies were performed. On 19 occasions, there were two positive results on the same day which could have led to contamination (0.07 p. 100). In 12 cases, there was heavy bacterial contamination on the first examination and at least 5 colonies on the second. Crossed transmission was not observed. The authors emphasize the role of the accessory parts and connections which are often neglected and which may lead to false positive results in the following patients; a sterilisation procedure is proposed which seems to be effective as no mycobacterial contamination has been observed since it was introduced.
