There have been numerous reports in the literature describing the diversity of microbial flora isolated from woodwind and brass instruments, with potential infection risks for players, especially when such instuments are shared. Steam disinfection has become established as a trusted method of decontamination, however, there have been no reports on the employment of this technology to disinfect parts of musical instruments, hence it was the aim of this study to examine the fate of bacterial and yeast pathogens on artificially contaminated trumpet mouthpieces and to evaluate whether such disinfection is an effective method of disinfection for such instrument parts. Trumpet mouthpieces were artificially contaminated with 18 microbial strains (17 bacteria from four genera [Enterococcus, Escherchia, Staphylococcus & Streptococcus] and one yeast [Candida]) each at an inoculum density of approximately 1.5 x 107 colony forming units and subjected to a disinfection cycle. The experiment was repeated including 50% [v/v] sterile sputum as soil. No bacteria or yeast organisms were recovered post disinfection, including following recovery and non-selective cultural enrichment techniques.
