目的:比较使用后经医院常规消毒的布尿布和家庭热水清洗处理后的布尿布中的微生物含量和种类的差别。方法:使用后的布尿布经医院常规消毒和家庭热水清洗处理后分别检测了细菌总数、霉菌/酵母菌、大肠杆菌的含量以及铜绿假单胞菌和耐甲氧西林金黄色葡萄球菌。结果:家庭热水清洗处理后的布尿布中64份尿布均检测出细菌,细菌总数的平均值为1450348 cfu/g;对32份样品中霉菌/酵母菌进行了检测,其中30份尿布中检测为阳性,其平均值为726.6 cfu/g;7份尿布中检测出大肠杆菌,平均值为721.1 cfu/g;对铜绿假单胞菌的鉴定均为阴性;46份尿布耐甲氧西林的金黄色葡萄球菌(MRSA)鉴定为阳性;经医院常规消毒后的布尿布中55份尿布中均检测出细菌,细菌总数的平均值为30.9 cfu/g;18份尿布中检测出霉菌/酵母菌,平均值为1.1 cfu/g;64份尿布中均未检出大肠杆菌;对铜绿假单胞菌的鉴定均为阴性;9份尿布耐甲氧西林金黄色葡萄球菌鉴定为阳性。采用经医院常规消毒方法的多重带菌率明显低于家庭热水清洗方法。结论:使用后经过医院常规消毒的布尿布中微生物的浓度明显低于家庭热水清洗处理后的布尿布,且霉菌/酵母菌、耐甲氧西林金黄色葡萄球菌和大肠杆菌是布尿布中的主要微生物。
OBJECTIVE: To compare the differences in microbial content and species in cloth diapers after being disinfected with cloth diapers and household hot water after disinfection. Methods: The total amount of bacteria, mold / yeast, Escherichia coli and Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were detected after routine use of cloth diapers by the hospital routine disinfection and domestic hot water cleaning treatment. Results: The average number of bacteria and bacteria in 64 diapers after home-hot water cleaning treatment was 1450348 cfu / g. The molds / yeasts in 32 samples were tested, of which 30 diapers Was positive, with an average of 726.6 cfu / g; Escherichia coli was detected in 7 diapers with an average of 721.1 cfu / g; negative for P. aeruginosa; 46 for methicillin resistant Staphylococcus aureus (MRSA) were identified as positive. Bacteria were detected in all 55 diapers in clinically sanitized cloth clinics, with an average of 30.9 cfu / g bacteria in total; 18 molds / yeasts were detected in 18 diapers, With an average of 1.1 cfu / g; no E. coli was detected in 64 diapers; negative for Pseudomonas aeruginosa; and 9 were resistant to methicillin-resistant Staphylococcus aureus. Multiple disinfection rates using conventional disinfection methods in hospitals were significantly lower than those of household hot water cleaning methods. CONCLUSIONS: The concentration of microorganisms in cloth diapers routinely disinfected in hospitals was significantly lower than that of cloth diapers after hot water cleaning in houses, and mold / yeast, methicillin-resistant Staphylococcus aureus and Escherichia coli were in cloth diapers Main microorganism.
