Nosocomial infections are a concern of growing interest in veterinary medicine. Clipper blades have been confirmed as fomites for numerous potential pathogens and, as such, may be associated with wound and surgical site infections. The goal of this study was to evaluate the disinfectant capabilities of several commonly used clipper blade cleaning products. Seventy sterile clipper blades were inoculated with strains of Pseudomonas aeruginosa , Escherichia coli , and Staphylococcus aureus . Blades were then subjected to one of seven treatment groups for disinfecting. Quantitative cultures of remaining bacteria were performed. All blades in the control group showed large amounts of bacterial recovery. Culture results showed no recovery in blades soaked in alcohol or chlorhexidine or those sprayed with an ethanol/o-phenylphenol product, while moderate recovery was seen with all other treatments. These results show that persistent contamination of clipper blades can occur with the use of several commonly used disinfectant products. Further research is necessary to evaluate fungicidal capabilities as well as the effect of disinfection on clipper blade maintenance.
医院感染是兽医医学中日益受到关注的问题。已证实推子刀片是多种潜在病原体的污染物，因此可能与伤口和手术部位感染有关。本研究的目的是评估几种常用推子刀片清洁产品的消毒能力。70个无菌推子刀片接种了铜绿假单胞菌、大肠杆菌和金黄色葡萄球菌菌株。然后将刀片置于七个消毒处理组之一进行处理。对剩余细菌进行定量培养。对照组的所有刀片均显示大量细菌复苏。培养结果表明，浸泡在酒精或洗必泰中的刀片或喷洒乙醇/邻苯基苯酚产品的刀片没有细菌复苏，而其他所有处理均出现中度复苏。这些结果表明，使用几种常用消毒产品可能会导致推子刀片持续污染。有必要进一步研究以评估其杀真菌能力以及消毒对推子刀片保养的影响。
