Stethoscopes can take part in the transmission of health care-associated infections. We cultured 112 stethoscopes by direct imprint on blood agar to estimate the prevalence of potentially pathogenic microorganisms. Forty-eight (47%) produced 50 potentially pathogenic microorganisms; from these, 43 (86%) were Staphylococcus aureus, of which 18 (42%) were methicillin-resistant S. aureus. We concluded that stethoscopes should be considered as potential fomites and must be disinfected routinely before and after each patient contact.
听诊器可能参与了医源性感染的传播。我们通过直接在血琼脂上印模培养了 112 个听诊器，以估计潜在致病微生物的流行率。48 个（47%）产生了 50 种潜在致病微生物；其中，43 个（86%）为金黄色葡萄球菌，18 个（42%）为耐甲氧西林金黄色葡萄球菌。我们得出结论，听诊器应被视为潜在的传播媒介，并且在每次接触患者前后都必须常规进行消毒。
