过硫酸氢钾复合盐对禽类常见细菌病原微生物杀灭效果观察
|
摘要
目的观察过硫酸氢钾复合盐对禽类常见细菌病原微生物的杀灭效果,为禽类圈舍消毒提供依据。方法采取悬液定性和定量方法,评估过硫酸氢钾复合盐杀灭大肠杆菌、鸭疫里默杆菌、金黄色葡萄球菌和沙门菌效果,并比较10℃、20℃和30℃试验温度对消毒剂杀灭大肠杆菌和沙门菌试验效果的影响。结果以杀灭细菌对数值> 5. 00的评价标准判断,5 min内过硫酸氢钾复合盐杀灭大肠杆菌、鸭疫里默杆菌、金黄色葡萄球菌和沙门菌时的最低杀灭浓度(活性氧含量)分别为230 mg/L、14. 375 mg/L、57. 5 mg/L和115 mg/L,试验温度10℃上升至30℃,过硫酸氢钾复合盐对大肠杆菌和沙门菌的杀菌效果明显升高。结论过硫酸氢钾复合盐对禽类常见细菌病原微生物有较好的杀灭效果,升高温度有助于提高过硫酸氢钾复合盐的杀灭效果。
Objective To observe the inactivation efficacy of the oxone monopersulfate compound in poultry pathogenic microorganism,and to provide the basis for poultry enclosure disinfection. Methods Suspension qualitative and quantitative methods were used to evaluate the disinfection efficacy of oxone monopersulfate compound on Escherichia coli,Riemerella anatipestifer,Staphylococcus aureus and Salmonella,and the germicidal efficacy on Escherichia coli and Salmonella at three different temperatures 10 ℃,20 ℃,30 ℃ were compared. Results With the evaluation criterion of the bactericidal logarithm values > 5. 00,the minimum bacteri cidal concentrations of oxone monopersulfate compound( based on the activating oxide content) for Escherichia coli,Riemerella anatipestifer,Staphylococcus aureus and Salmonella were 230 mg/L,14. 375 mg/L,57. 5 mg/L and 115 mg/L in 5 minutes,respectively. And in the range of temperature test,the bactericidal effect of oxone monopersulfate compound on Escherichia coli and Salmonella was significantly increased when the test temperature raised from 10 ℃ to 30 ℃. Conclusion It's proved that oxone monopersulfate compound possessed excellent laboratory efficacy in killing poultry pathogenic microorganism,and increasing the temperature is helpful to improve its inactivation efficacy.
