摘要
目的 比较4种不同培养基在检测口腔综合治疗台菌落总数结果的不同，以及口腔综合治疗台不同采样点菌落总数的区别。方法 5台A-dec口腔综合治疗台分别于消毒前在漱口水、三用喷枪、高速手机、洁牙机4个采样点进行采样，用4种不同的培养基进行细菌培养，重复3次，比较细菌菌落计数。结果 生活饮用水标准检验方法推荐培养基、医疗机构消毒技术规范推荐培养基、改良胰蛋白胨大豆琼脂培养基细菌培养结果无统计学差异，与R2A培养基培养结果有统计学差异；三用喷枪、高速手机、洁牙机采样点细菌培养计数无统计学差异，与漱口水采样点细菌培养计数结果有统计学差异。

Abstract
Objective To compare the results of four different media in detecting the total number of bacterial colonies on oral comprehensive treatment table, and the difference of the total number of bacterial colonies at different sampling points on oral comprehensive treatment table. Methods Before disinfection, 5 A-dec oral comprehensive treatment tables were sampled at 4 sampling points, including mouthwash, spray gun, high-speed mobile phone and dental cleaning machine, respectively. 4 different media were used for bacterial culture, repeated 3 times, and the bacterial colony count was compared. Results There was no statistical difference in the results of bacteria culture in the medium recommended by the standard test method of drinking water, the medium recommended by the technical specification of disinfection in medical institutions, and the improved peptone soybean AGAR medium, but there was statistical difference between the results and R2A medium. There was no statistical difference in the bacterial culture count of the sampling points of the spray gun, high-speed mobile phone and dental cleaning machine, but there was statistical difference in the bacterial culture count results of the sampling points of mouthwash.
Key words： Oral medium; Oral comprehensive treatment table waterway; Bacterial infection; Infection control
