摘要
目的 :观察MEBO对生长繁殖 8h的细菌的作用。方法 :将细菌 (变形杆菌、大肠杆菌、绿脓杆菌、金黄色葡萄球菌 )接种在琼脂培养基上 ,置 37℃培养 8h ,取出于接种细菌的表面涂抹上MEBO继续置 37℃培养。分别于培养 3h、5h、7h、9～ 10h取出涂片观察。结果 :MEBO对生长繁殖 8h的细菌除葡萄球菌的形态基本同原菌外 ,其余三种细菌都于 3h就观察到长短不等的杆菌。于 9～ 10h都呈现小球杆菌。而在整个培养过程中未见到长丝状变异。结论
Objective: To observe the effect of MEBO on the bacteria which have grown and proliferated for 8 hours. Method: B. proteus. B. coli, B. pyocyaneus and Staphylococcus aureus were inoculated separately on agar medium dish and incubated for 8 hours at 37 oC. The surface layer of the culture medium was taken out and spread with MEBO and then continue to incubate at 37 oC and the results were observed at 3h, 5h and 9-10 h respectively. Results: Except S. aureus, the other 3 species of bacteria had morphological changes, in 3 h rods with different length were found and in 9-10 h small sphere appeared. No filamentous mutation was found. Conclusion: MEBO has significant antibacterial effect at the growing stage of the bacteria.
